CL05B102KB5NNNC Descripción general
A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating layers of nickel inner electrodes and a ceramic dielectric. The X7R dielectric classification (per EIA-198) means -55°C to +125°C operating range with ±15% capacitance variation across that band. Compared to C0G/NP0 (Class I) parts, X7R offers substantially higher volumetric efficiency (more capacitance per mm3) at the cost of higher temperature coefficient and lower Q. MLCCs sit below supercapacitors, aluminum electrolytics, and film capacitors in the passive-component hierarchy and are the workhorse decoupling and bypass device in modern digital electronics.
Key specifications include 1000 pF nominal capacitance, ±10% tolerance (K code), 50 V DC rated working voltage, X7R temperature characteristic, and a 0402 case size (1.00 x 0.50 x 0.50 mm). The termination finish is nickel-barrier with matte-tin plating for excellent solderability and resistance to leaching during reflow. The device is qualified to Samsung's standard reliability test program including temperature cycling, bias humidity, and thermal shock, and is supplied in compliance with RoHS, REACH, and halogen-free directives.
Electrically, the X7R dielectric delivers moderate-to-high volumetric efficiency and reasonably stable performance in audio coupling, decoupling, and filter networks. At 1 nF the part sits in a useful mid-range capacitance window: large enough for general IC decoupling on sub-100 MHz digital rails, small enough for analog filter sections and high-frequency bypass duty. Equivalent series resistance (ESR) is low and self-resonant frequency is well above 100 MHz, supporting broadband noise suppression.
Typical applications include high-frequency decoupling of microcontrollers (PIC32MZ, STM32, Kinetis), DC blocking in audio line-level signal paths, RC time-constant networks in oscillators and timers, EMI/RFI bypass on analog sensor lines, and general-purpose bypass capacitors on low-voltage (3.3 V / 5 V) power rails. Designers routinely select 1 nF 0402 X7R capacitors for tight PCB layouts where 0201 pad geometry is impractical and where C0G stability is not required.
When designing with the CL05B102KB5NNNC, observe the 50-V working voltage derating guideline of roughly 50% in high-reliability applications (target 25 V or below for long-term reliability). Place the device within 2-3 mm of the IC supply pin and use wide, short traces to minimize parasitic inductance. For noise-sensitive analog circuits, prefer C0G/NP0 alternatives; for high-density digital decoupling, parallel multiple 100 nF and 1 nF X7R parts for broadband supply noise suppression.

Aplicaciones típicas
CL05B102KB5NNNC es adecuado para 6 aplicacións: Microcontroller Power Rail Decoupling, Audio Line Coupling and DC Blocking, RC Time Constant and Oscillator Networks, Analog Sensor Signal Filtering, USB and High-Speed Data Line Bypass, EMI Suppression and RFI Snubbing.
Microcontroller Power Rail Decoupling
The CL05B102KB5NNNC's 1 nF capacitance in a compact 0402 footprint makes it an ideal local decoupling capacitor on microcontroller power rails such as PIC32MZ2048EFM144 series, STM32, and Kinetis MCU supplies. At 1 nF the self-resonant frequency is well above 100 MHz, allowing the part to effectively suppress mid-frequency noise between the dominant 100 nF bulk capacitor and the smaller 10 pF high-frequency bypass. Place within 2-3 mm of the IC VDD pin, route wide and short traces to minimize parasitic inductance, and parallel with a 100 nF X7R for broadband digital decoupling. Unlike C0G alternatives, X7R offers sufficient volumetric efficiency at this small footprint for cost-sensitive consumer and IoT designs.
Recomendado
Audio Line Coupling and DC Blocking
In audio line-level signal paths, the CL05B102KB5NNNC serves as a DC blocking capacitor where the 1 nF value combined with typical 10 kΩ-100 kΩ source and load impedances produces a high-pass cutoff well below the audible 20 Hz band. The X7R dielectric's ±15% variation across -55 °C to +125 °C is acceptable for line-level coupling where ultimate precision is not required, but for audiophile-grade signal paths the same capacitance is more commonly built with C0G/NP0 0402 parts. The 0402 footprint allows tight placement near op-amp input pins, minimizing loop area and reducing susceptibility to EMI pickup.
Recomendado
RC Time Constant and Oscillator Networks
The CL05B102KB5NNNC is well suited for RC timing networks in 555-timer circuits, relaxation oscillators, and PLL loop filters where the 1 nF capacitance combined with 10 kΩ-100 kΩ resistors produces time constants in the 10 µs to 100 µs range. The ±10% tolerance (K code) gives roughly ±10% frequency variation in monostable or astable configurations, which is acceptable for non-precision timing applications. For crystal oscillator load capacitors, however, designers should select C0G/NP0 parts instead, since X7R's temperature dependence would shift the load capacitance and destabilize the oscillator.
Recomendado
Analog Sensor Signal Filtering
Sensor signal chains from thermocouples, RTD bridges, photodiodes, and analog accelerometers often need a 1 nF low-pass filter on the analog signal line to suppress RF interference above the sensor's bandwidth. The CL05B102KB5NNNC in a 0402 package can be placed directly at the ADC input pin of a 24-bit sigma-delta converter, forming a single-pole RC filter with the input amplifier's impedance. The X7R dielectric is sufficient for anti-aliasing filters, and the 50 V rating provides ample margin for sensor bias networks operating at 5 V or less.
Recomendado
USB and High-Speed Data Line Bypass
USB 2.0 data lines, HDMI link signals, and LVDS pairs require small-value bypass capacitors to ground for common-mode noise suppression without disturbing the high-speed differential signal. The CL05B102KB5NNNC's 0402 footprint and 1 nF value make it suitable for inline shunt capacitors on D+/D- or signal-pair shielding networks, where the X7R dielectric's modest loss at 100 MHz-1 GHz is acceptable for common-mode but not differential filtering. Designers should place the part within 5 mm of the connector pin to maintain effectiveness at higher frequencies.
Recomendado
EMI Suppression and RFI Snubbing
Across switching power supply feedback loops, relay driver outputs, and motor control PWM signals, the CL05B102KB5NNNC provides local RFI suppression by shunting high-frequency noise to ground. The 0402 package allows placement directly at the offending node, while the 1 nF value forms a low-impedance path above 10 MHz when paired with typical 50 Ω-1 kΩ circuit impedances. The X7R dielectric handles the high dV/dt switching transients without significant piezoelectric ringing, and the 50 V rating covers most sub-48 V industrial and automotive subsystems.

Notas de diseño
Place the CL05B102KB5NNNC within 2-3 mm of the IC supply pin it is decoupling, and use wide, short traces (preferably 0.20 mm or wider) connecting both terminals directly to the IC and ground. Minimize via count - one via per terminal is the practical maximum. For multi-layer boards, place the capacitor on the top layer with a solid ground plane on layer 2 directly beneath to minimize loop inductance and improve high-frequency noise suppression above 100 MHz.
Do not apply AC or DC voltage exceeding the 50 V rated working voltage, including transient spikes from switching converters or relay coils. In high-reliability designs, derate to 25 V (50% of rating) for continuous operation to extend lifetime. Be aware that X7R capacitance drops with applied DC bias voltage (typically 10-15% at rated voltage for 1 nF parts); use a higher nominal capacitance if the circuit requires precise value under bias.
Follow the recommended land pattern in the Samsung CL05B102KB5NNNC datasheet: two 0.50 mm x 0.60 mm pads with 0.40 mm gap, giving 1.00 mm total land length. Use NSMD (Non-Solder Mask Defined) pads for best solder joint reliability, and avoid placing the part in regions of high mechanical stress such as board edges, mounting screw heads, or connector strain-relief areas where flexure can crack the ceramic body.
