UWT1V101MCL1GS 개요
An aluminum electrolytic capacitor is a polarized wet-electrolyte storage element in which an etched aluminum anode and a cathode foil separated by a paper spacer are wound into a cylindrical can and impregnated with an electrolyte. It belongs to the broader electrolytic capacitor family and the still-broader capacitor hierarchy (capacitor > electrolytic capacitor > aluminum electrolytic capacitor > SMD aluminum electrolytic capacitor). Within power management circuits the UWT sits between the switching regulator output node and downstream loads as a bulk-decoupling and energy-storage element, where its high volumetric efficiency per microfarad and cost-per-volt-second outweigh its higher ESR compared with ceramic or polymer alternatives.
Key features include 100uF nominal capacitance at +/-20% tolerance, 35V rated DC working voltage, 0.084A (84mA) maximum ripple current rating at 120Hz, and a vertical SMD form factor with surface-mount compatible leads that are auto-insertion ready. The Ni-barrier termination supports lead-free reflow profiles to J-STD-020, while the external can is sleeved for marking and identification. The radial can-SMD geometry offers higher ripple-current handling and capacitance density than comparable tantalum or polymer chip capacitors in the same footprint.
Technically, the UWT1V101MCL1GS uses a high-purity etched aluminum foil anode with a controlled-oxide dielectric layer to achieve the stated capacitance in the 6.3mm x 7.7mm can, while the liquid electrolyte provides the cathode connection and self-healing behavior that distinguishes aluminum electrolytics from solid polymer types. Designers select the UWT family when they need a robust, low-cost bulk capacitor that survives automotive thermal-cycling profiles and complies with the RoHS substance restrictions that prohibit lead, cadmium, and certain phthalates.
Typical applications include 5V/12V/24V automotive ECU power-rail bulk filtering, DC-DC converter output smoothing after a switching regulator, LED driver input and output capacitance, and industrial control board general-purpose filtering where AEC-Q200 qualification is required. The combination of small case size, wide temperature rating, and reflow compatibility allows direct placement on dense, mixed-technology PCBs in place of older through-hole parts.
When designing with this part, always observe polarity - the cathode stripe and shorter lead indicate negative - and ensure that the peak ripple current stays below 84mA at 120Hz for reliable operation within the 1000-hour 105C lifetime rating. For longer-life or higher ripple applications, consider the Nichicon UWD series (2,000 hours) or UVR series (5,000 hours) in the same case size. Verify that the working voltage derates with temperature per the datasheet, and always use a ceramic bypass in parallel for high-frequency decoupling above the electrolytic's self-resonance point.

일반적인 애플리케이션
UWT1V101MCL1GS 적합 용도: 7 애플리케이션s: Automotive ECU Power-Rail Bulk Filtering, DC-DC Converter Output Smoothing, LED Driver Input and Output Filtering, Industrial PLC and Factory-Automation Supplies, Consumer and Appliance Power-Board Bulk Decoupling, USB and 5V VBUS Bulk Capacitance, Surveillance and Security Camera Boards.
Automotive ECU Power-Rail Bulk Filtering
Use the Nichicon UWT1V101MCL1GS on automotive ECU power inputs to provide bulk 100uF storage capacitance on 12V and 24V supply rails. The part's 35V rating gives comfortable margin against 24V load-dump spikes seen in 24V truck systems, while its AEC-Q200 qualification guarantees the part survives -55C to +105C thermal-cycling and vibration profiles of under-hood and body-electronics modules. Decoupling occurs at frequencies below the self-resonance of the wet-electrolytic construction, with smaller 100nF ceramic X7R capacitors placed in parallel for high-frequency switching noise suppression.

DC-DC Converter Output Smoothing
Place the UWT1V101MCL1GS at the output of a 24V-to-5V buck converter to absorb the inductor ripple and supply transient loads for downstream digital and analog ICs. The 84 mA ripple current rating at 120 Hz and 35V voltage tolerance let it handle the full switching-cycle current swing of a 1-2 A step-down regulator at moderate switching frequencies. Compared with a ceramic-only output stage, adding the UWT cuts the loop C_out requirement and provides sustained holdup time during input voltage drops of the order of milliseconds.
추천
LED Driver Input and Output Filtering
Bulk-decouple the input of a high-brightness LED driver with the UWT1V101MCL1GS to filter PWM controller supply ripple and smooth out sudden current steps driven by PWM dimming transitions. Its 105C continuous temperature rating is suitable for LED-driver environments where fixture heat and forward-current dissipation elevate ambient temperature inside the luminaire. For best results combine the UWT bulk capacitor with a low-ESR ceramic bypass to suppress the PWM-edge high-frequency ringing that exceeds the electrolytic's self-resonance.
추천
Industrial PLC and Factory-Automation Supplies
Filter 24V factory-bus power entering PLC analog-input, analog-output, and relay-driver modules using the Nichicon UWT1V101MCL1GS. The 1000-hour 105C rated lifetime matches typical industrial control room thermal environments, while RoHS compliance keeps the part inside EU machinery directives. Apply on both sides of isolated DC-DC converter modules to lower common-mode noise and give the regulated rail enough stored charge to ride through momentary brownouts on the industrial 24V bus.
추천
Consumer and Appliance Power-Board Bulk Decoupling
Decouple the secondary side of a small switch-mode power supply in white-goods, set-top boxes, and home appliances using the UWT1V101MCL1GS. With 100uF capacitance, the part provides enough energy storage to reduce output voltage ripple below the level that confuses downstream microcontrollers or audio DACs. Its reflow-compatible SMD package and lead-free Ni-barrier terminations support modern Pb-free SMT assembly lines used by contract electronics manufacturers in this market segment.
추천
USB and 5V VBUS Bulk Capacitance
Use the UWT1V101MCL1GS on the 5V VBUS rail of USB Type-A and Type-C downstream ports to supply the bulk decoupling capacitance required to meet USB hot-plug surge and inrush-current tests. Its 35V rating means the part also survives accidental application of 12V-24V automotive or industrial supply transients, which is helpful in dual-environment charging hubs. Place a 10uF ceramic in parallel to handle the high-frequency load-step response of modern USB-PD controllers.
추천
Surveillance and Security Camera Boards
Place the Nichicon UWT1V101MCL1GS on PoE-extracted, 12V-powered or 5V-powered camera boards to filter the local PoE-rectified DC feed before downstream switching regulators. With its 100uF bulk storage and 35V voltage tolerance, the part tolerates wide PoE supply variations typical of longer cable runs and supports the IR-LED driver and image-sensor analog supplies simultaneously. The AEC-Q200 rating adds extra reliability margin for outdoor camera enclosures that can swing widely in temperature.

설계 노트
The UWT1V101MCL1GS is a polarized aluminum electrolytic - inserting the part in reverse polarity damages the dielectric, generating heat and electrolyte gas that can rupture the vent. Always orient the stripe-marked cathode to the negative side of the rail and pre-bend or pre-form the leads if a through-hole bypass is needed. A series protection fuse or reverse-polarity MOSFET on the input power path is recommended when fault tolerance is required.
Land pattern must match the manufacturer recommended 6.3mm can with two solder pads offset along the polarization axis; reference Nichicon's UWT-series reflow-soldering specifications for the exact pad dimensions. The capacitor should be placed close to the IC supply pin with a parallel 100nF-10uF ceramic bypass for high-frequency decoupling. Estimated: a 9.5mm x 3.5mm land area is typical for this 6.3x7.7mm can based on Nichicon SMD V-chip capacitor land-pattern guidelines.
Verify steady-state DC voltage stays at least 20% below the 35V rating to ensure acceptable leakage current and lifetime per the Nichicon UWT datasheet. Keep core temperature below 105C by limiting ripple current to the 84 mA rating at 120 Hz and applying the appropriate frequency derating above 10 kHz. For boards operating at the upper temperature limit, select the longer-life Nichicon UWD (2000 hours) or UVR (5000 hours) series at the same case size for design margin.
Estimated: at 84 mA ripple current and 105C ambient, the part's self-heating and equivalent-series resistance dissipate on the order of 10-20 mW in a 6.3x7.7mm can, which is small relative to ambient thermal mass but rises rapidly in enclosed fixtures. Provide at least 5 mm of clearance around the can for convection airflow, or use thermal vias through a copper thermal pad to spread heat into inner copper layers of the PCB. AEC-Q200 qualification requires the part to survive 1000 thermal cycles between -55C and +105C, which is satisfied by the UWT rating.
