112 - Mini Screw Incandescent Lamp 1.2V 264mW | CEC Industries
The CEC Industries 112 is a subminiature incandescent lamp rated at 1.2 V and 264 mW, housed in a miniature screw (E5) base. It is a filament-based indicator and illumination source commonly used in panel meters, status indicators, medical instruments, and aviation cockpit panels where a reliable, low-voltage incandescent point source is required. An incandescent lamp is a heritage lighting technology in which a tungsten filament is heated to incandescence by an electrical current, producing visible light through black-body radiation. Within the broader optoelectronics hierarchy, incandescent lamps sit alongside LEDs, neon lamps, and electroluminescent devices as direct-radiant point sources, distinguished from solid-state emitters by their warm correlated color temperature (~2700 K), high color rendering index (CRI ~100), and instantaneous warm-up. They remain preferred where broadband spectrum or electromagnetic compatibility with legacy equipment is required. Key features of the 112 include its 1.2 V nominal operating voltage (designed for a single Ni-Cd or Ni-MH cell), 220 mA nominal lamp current, 264 mW power dissipation, a typical service life in the hundreds of hours, and a miniature Edison screw base for tool-free socket replacement. The bulb envelope is constructed of hard glass, providing resistance to thermal shock and mechanical handling in industrial environments. From a design standpoint, the 112 operates as a purely resistive load. Its cold-to-hot filament resistance ratio of approximately 1:14 means that inrush current at switch-on is substantially higher than steady-state current, an important consideration for the driver circuit and any series-dropping components. The lamp's broadband emission spectrum makes it suitable for applications that require accurate color rendering or where the warm-up characteristic is functionally useful. Typical applications include aircraft cockpit instrumentation, marine panel indicators, telecommunications equipment status panels, vintage radio dial lamps, and process-control annunciators. Designers should size the supply voltage and current-limiting network around the published V-I characteristic, derate for vibration, and provide adequate ventilation to maintain the rated filament temperature. When designing with this lamp, allow at least 10% voltage headroom below the maximum rating and confirm that the supply can deliver the inrush current without sagging. Long-term reliability is dominated by filament evaporation; gentle inrush limiting (NTC thermistor or soft-start) extends service life.

LTST-S326KGJRKT - Dual-Color Side-View SMD LED | Lite-On
The Lite-On LTST-S326KGJRKT is a dual-color (green and red) side-view surface-mount LED indicator housed in a 2-SMD, no-lead package measuring 3.0 x 2.0 x 1.0 mm. The green channel emits at a dominant wavelength of 571 nm and the red channel at 631 nm, with typical forward voltages of 2 V each at the rated test current of 20 mA. The device uses an ultra-bright AlInGaP chip and features a clear water-clear lens with a 130-degree viewing angle suited for lateral light emission. An indicator LED is a semiconductor light-emitting diode used as a discrete visual or status signal in electronic equipment. Single-color and dual-color discrete LEDs sit at the lowest tier of the optoelectronic hierarchy (LED indicator -> standard LED -> optoelectronic component -> semiconductor device) and serve as the simplest optical interface between a circuit and a user. The LTST-S326KGJRKT combines two independently drivable color dice in one side-view package, which makes it a space-efficient dual-state indicator without requiring two separate SMD footprints. Key features of the LTST-S326KGJRKT include a side-looking optical axis designed for edge-lit backlighting of LCD panels, a luminous intensity of approximately 35 mcd for green and 25 mcd for red, and full compatibility with 8 mm tape-and-reel automatic placement equipment. It supports both infrared and vapor-phase reflow soldering processes, has EIA-standard IC-compatible packaging, and conforms to the RoHS green-product directive. The molded SMT construction uses a 2-SMD, no-lead termination style. From a technical perspective, the LTST-S326KGJRKT integrates an AlInGaP red emitter and an InGaN or AlInGaP green die in a single molded body. Each color is biased independently through its own anode and cathode, so the indicator can show green, red, or any mixed hue between by adjusting the relative drive currents. The side-view optical design places the emitting surface on the package's narrow edge, allowing the device to be placed flat against an LCD's light-guide input without obstructing the display area. Typical applications include status indicators in cordless and cellular phones, notebook computers, network equipment, home appliances, and indoor signboard backlighting. The dual-color capability supports multi-state alerts such as charging (red) versus fully charged (green), and the side-view geometry is well matched to edge-lit LCD modules. When designing with this part, observe the standard LED drive method: place a current-limiting resistor in series with each color channel and avoid paralleling multiple LEDs without per-string resistance. The 7-inch reel EIA packaging supports standard pick-and-place assembly lines.

XL-HD3535SURC-A2 - 1W 3535 Red LED, 350mA, 625nm | XINGLIGHT
The XINGLIGHT XL-HD3535SURC-A2 is a high-power red LED in a 3.5 x 3.5 x 2.2 mm SMD-3535 package with a transparent water-clear colloid, optimized for camera flash, flashlight, and high-intensity general lighting applications. It delivers 40-60 lm of luminous flux at a dominant wavelength of 615-625 nm (typ. 625 nm), driven at a forward current of 350 mA with a forward voltage of 1.8-2.4 V. The viewing angle is 130 degrees, providing broad and even light distribution in compact optical assemblies. A high-power LED is a semiconductor light source that converts electrical energy into light with higher current density and luminous flux than standard indicator LEDs, requiring constant-current drive and thermal management to maintain reliability. Within the LED taxonomy, the XL-HD3535SURC-A2 falls under high-power LEDs, which sit between standard indicator LEDs (typically 20 mA) and LED COB/CSP modules (>5 W). Its 3535 metric footprint places it in the mid-power surface-mount category used in portable, automotive, and architectural lighting fixtures. Key features include a 1 W power rating, a peak pulsed forward current capability above 350 mA, an electrostatic discharge threshold consistent with JEDEC MSL-3 handling, and a wide operating temperature range of -40C to +85C. The epoxy resin lens is water-clear, allowing maximum luminous intensity with minimal color absorption. The 130-degree beam profile enables wide-area illumination without secondary optics. Technically, the device uses an AlGaInP (aluminum gallium indium phosphide) epitaxial structure on a GaAs substrate, the standard material system for high-brightness red and amber LEDs in the 615-630 nm band. The 3535 ceramic-look package supports efficient heat transfer from the die junction to the PCB land pad, which doubles as the thermal pad. Junction-to-ambient thermal resistance is on the order of 20-30 C/W per JEDEC standard test conditions. Typical applications include camera phone flashes, tactical flashlights, decorative stage lighting, signage and beacon systems, automotive interior/exterior accent lighting, and high-end indicator strips. The 625 nm dominant wavelength produces a saturated deep-red color well-suited for warning indicators and decorative effects. When designing with the XL-HD3535SURC-A2, drive it with a constant-current source rather than constant voltage to avoid thermal runaway. Provide adequate copper area (typically >= 25 mm^2) under the thermal pad to keep the junction below 125C at full 350 mA drive.

XL-HD3535UGC-A4 - 3W Green SMD LED 110-150lm 525nm | XINGLIGHT
The XINGLIGHT XL-HD3535UGC-A4 is a high-power green SMD LED housed in a compact 3.5 x 3.5 x 2.2 mm 3535 metric package, delivering a typical luminous flux of 110-150 lm at a forward current of 350 mA. It uses a transparent water-clear colloid, exhibits a 120-degree half-light viewing angle, and emits at a dominant wavelength of 515-535 nm with a typical peak of 525 nm. The device is rated for 3.4 V typical forward voltage and 3 W maximum power dissipation, making it suitable for camera flash, stage lighting, and signage backlighting. A discrete SMD LED in the 3535 metric footprint is a chip-on-board-style light-emitting diode that combines a high-brightness semiconductor die, an optical-grade silicone or epoxy lens, and thermally-conductive package leads. Compared with smaller 0805 or 1206 indication LEDs, 3535 high-power LEDs dissipate several watts of heat and require careful thermal management via PCB copper pours. Within the optoelectronics hierarchy, this part sits under LED Indication - Discrete, then broader categories of LEDs and Optoelectronics, providing monochromatic point-source illumination for general lighting, signalling, and indicator roles. Key features include 110-150 lm typical luminous flux at IF = 350 mA and Ta = 25 °C, dominant wavelength 515-535 nm, peak wavelength 525 nm typical, 120° viewing angle, transparent water-clear lens, and an operating temperature range of -40 °C to +125 °C. The 3535 metric package is reflow-compatible with standard lead-free profiles and provides a low thermal-resistance path from junction to solder pad, enabling the LED to sustain high drive currents in compact luminaires. Internally, the XL-HD3535UGC-A4 uses an InGaN (Indium Gallium Nitride) green die bonded onto a thermal-enhanced lead frame. The transparent silicone lens concentrates the die's lambertian emission into a wider 120° pattern, which simplifies optical design for area lighting. Junction-to-solder-pad thermal resistance is engineered to keep junction temperature rise within safe limits at 350 mA continuous drive, which is critical for lumen maintenance and color stability over operational life. Typical applications include mobile-camera flash and smartphone strobe modules, architectural and stage lighting fixtures, horticulture grow-light panels (when supplemented with red and blue channels), decorative signage and accent lighting, indicator strips in industrial equipment, and portable lighting such as bicycle headlamps or emergency flashlights. The wide 120° beam eliminates the need for a secondary optic in many flat-panel designs. When designing with this LED, always provide adequate copper thermal relief on the anode and cathode pads - minimum 1 oz copper pour connected by thermal vias to the opposite side plane is recommended for continuous 350 mA operation. Drive the LED with a constant-current source; voltage-driven operation will cause thermal runaway and reduce lumen maintenance. ESD precautions (anti-static wrist strap, ionizer) must be observed during handling because InGaN dies are ESD-sensitive.

XL-HD3535WWC - 1W Warm White 3535 SMD LED | XINGLIGHT
The XINGLIGHT XL-HD3535WWC is a high-brightness warm white SMD LED in a 3.5 mm x 3.5 mm x 2.0 mm 3535 surface-mount package, delivering 80-100 lumens of luminous flux at 350 mA forward current with a typical forward voltage of 3.6 V. It is specified across a warm white correlated color temperature (CCT) range of 2800 K to 3200 K, with a water-clear encapsulant and 120-degree viewing angle for broad illumination coverage. A high-power LED is a solid-state semiconductor light source that converts electrical energy directly into photons through electroluminescence. Within the broader optoelectronics taxonomy, an LED sits at the component level (LED) -> discrete semiconductor -> optoelectronic device -> semiconductor device, with high-power variants differentiated by their ability to handle continuous forward currents in the hundreds of milliamps (versus indicator LEDs that operate at 10-20 mA). High-power LEDs require thermal management via PCB copper pours and often employ phosphor-converted white spectra from a blue die plus yellow phosphor combination. Key features include a maximum continuous forward current rating of 350 mA, a maximum pulse forward current that supports strobe and flash operation, a thermal resistance suitable for SMT reflow assembly, and an MSL 3 moisture sensitivity rating. The 3535 footprint has become an industry-standard package for camera flash and portable lighting applications due to its balance of thermal performance and compact size. The water-clear lens encapsulant provides high luminous intensity and uniform beam distribution across the 120-degree viewing angle. The XL-HD3535WWC uses a vertical chip architecture on a ceramic substrate or lead-frame lead-based package, with phosphor-converted warm white emission. The package is engineered for high peak current handling during strobe operation, where brief current pulses far exceeding the continuous rating are tolerated due to low duty cycle, making it suitable for smartphone camera flash and digital video auxiliary lighting applications. Typical applications include mobile camera flash, digital video lighting, portable flashlights, automotive interior illumination, and architectural accent lighting. The warm white color temperature makes it particularly suited for skin-tone-friendly photography, hospitality lighting, and decorative installations where a softer color temperature is preferred. When designing with this device, ensure adequate thermal management through copper pours on the PCB - at 350 mA forward current and 3.6 V forward voltage, the device dissipates approximately 1.26 W, requiring thermal vias or copper area to maintain junction temperature within specified limits. Drive configurations for strobe operation should observe the maximum pulse ratings from the datasheet, with appropriate current limiting and pulse width control.
