CL21B104KCCWPNC Обзор
A multilayer ceramic capacitor (MLCC) is a passive surface-mount component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic body and finished with solderable terminations. MLCCs sit in the broader passive component taxonomy as fixed-value capacitors, then specialize by dielectric class (C0G/NP0 for stability, X7R for general purpose, Y5V for high-K bulk capacitance, X5R for portable applications). X7R is the most popular industrial-grade dielectric because it offers a balanced trade-off between volumetric efficiency, temperature stability, and cost.
Key features include a 100 VDC rated voltage, ±10% capacitance tolerance (K code), X7R dielectric per EIA-198 classification, and lead-free reflow-solderable terminations compatible with JEDEC J-STD-020 lead-free reflow profiles up to 260 °C peak. The CL21B104KCCWPNC ships on 7-inch paper tape and reel per EIA 481 and qualifies to MSL-1 (unlimited floor life), simplifying logistics for high-volume SMT lines.
Internally the device uses a Class-II X7R dielectric whose permittivity drops predictably with temperature and applied DC bias, in contrast to Class-I C0G/NP0 dielectrics that are nearly unaffected by these stresses. The chip also exhibits a typical piezoelectric response that can be audible under certain AC ripple conditions; designers should bias this part appropriately or choose C0G if microphonics matter in the application.
Typical applications include decoupling of microcontroller and DSP power pins, general-purpose bypassing around op-amps and ADC references, RC filter networks, snubbers for switching converter edges, and timing/oscillator support stages. The 100 V rating also makes it useful in industrial 24 V / 48 V bus and small-signal coupling paths where higher voltage margin is desirable.
When designing with this device, derate working voltage by at least 50% for reliability-sensitive designs, account for DC-bias capacitance loss (typically 10–30% at full rated voltage on small 0805 X7R chips), and place the part within the MLCC keep-out zone under flexure-sensitive pads per IPC-9592 guidelines.

Типичное применение
CL21B104KCCWPNC подходит для 6 применениеs: Microcontroller Power Decoupling, Industrial 24V Sensor Signal Filtering, Switching Converter Snubber Networks, Op-Amp Power Supply Bypass, RC Timing and Oscillator Support, Automotive ECU Bypass and Coupling.
Microcontroller Power Decoupling
The CL21B104KCCWPNC's 0.1 µF capacitance and X7R dielectric make it a textbook bypass cap placed within 1 mm of each MCU VDD/VCC pin. With a 100 V rating, the device tolerates the high inductive transients present on industrial 24 V input rails after pre-regulation. The 0805 footprint accommodates 1 A of decoupling current with negligible impedance at 1–100 MHz, and the Ni-Sn termination supports standard 260 °C reflow profiles used on automotive and industrial lines. Designers commonly pair it with a 10 µF bulk cap for multi-decade noise suppression.

Industrial 24V Sensor Signal Filtering
Industrial 4–20 mA loops, PLC analog inputs, and 24 V proximity sensors commonly require R-C low-pass filters operating at rail potentials up to 30 V. The CL21B104KCCWPNC's 100 V rating provides 3:1 derating margin on these 24 V systems, while its 0.1 µF value pairs with 10 kΩ to 100 kΩ sense resistors to form sub-millisecond response filters. X7R's ±15% capacitance variation over -55 °C to +125 °C ensures predictable filter cutoff across outdoor or under-hood thermal swings.
Рекомендуется
Switching Converter Snubber Networks
Buck, boost, and flyback converters generate voltage spikes across rectifier and switch nodes that benefit from small ceramic snubbers. The CL21B104KCCWPNC serves as a parallel snubber across low-side rectifiers in 12 V–48 V converters, where its 100 V rating survives ringing overshoots that would punch through 25 V or 50 V X7R alternatives. Its 0805 footprint dissipates the snubber loss without thermal stress, and the low ESL supports effective damping of 10–50 MHz ringing.
Рекомендуется
Op-Amp Power Supply Bypass
Precision op-amps and ADCs require low-impedance local bypass to suppress PSRR rolloff above 1 MHz. The CL21B104KCCWPNC's 0.1 µF capacitance in 0805 gives a self-resonant frequency near 10 MHz, ideal for bypassing the high-frequency noise riding on the analog supply. The 100 V rating suits high-voltage op-amps used in instrumentation amplifiers and ultrasound front-ends. Place the cap directly between the op-amp supply pin and ground, with the ground via placed close to the cap's ground termination.
Рекомендуется
RC Timing and Oscillator Support
In 555 timer, RC relaxation oscillator, and PLL loop-filter circuits, the CL21B104KCCWPNC's 0.1 µF value combines with precision resistors to set timing periods from microseconds to milliseconds. X7R's predictable temperature coefficient (±15%) makes it acceptable for non-critical timing, while its 100 V rating handles the elevated rails of certain industrial timing circuits. For precision oscillators requiring better than 5% frequency stability, designers should consider C0G/NP0 alternatives instead.
Рекомендуется
Automotive ECU Bypass and Coupling
The CL21B104KCCWPNC's automotive-grade construction, AEC-Q200 test-acceptability via Samsung's MLCC catalog, and 100 V rating suit it to ECU bypass and high-side coupling in 12 V/48 V architectures. It survives engine-bay temperature swings to +125 °C and load-dump transients that exceed 24 V momentarily. Designers typically place multiple 0.1 µF 0805 X7R chips in parallel to spread ESL and ESR across the ECU power tree, using this Samsung part as the high-voltage-rated member of the parallel bank.

Заметки по проектированию
DC-bias capacitance loss is the most common surprise with the CL21B104KCCWPNC. Small-case X7R 0805 chips can lose 10–30% of nominal capacitance at full 100 V rated bias due to dielectric saturation. When designing RC filters, oscillators, or charge-pump timing circuits, derate to 50 V working voltage (50% of rated) to stay in the flat region of the C-vs-V curve. Use the manufacturer's SPICE models or DC-bias characterization charts for precise budgeting.
Place the CL21B104KCCWPNC within 1–2 mm of the IC pin it bypasses, with traces short and wide to minimize series inductance. Use two vias per termination when possible (one signal via, one ground via placed adjacent to the cap's ground pad) to reduce ground bounce. Avoid placing the cap on flexure-sensitive areas such as board edges or under connectors - X7R ceramics can crack under excessive PCB flexure.
For high-frequency decoupling above 10 MHz, the CL21B104KCCWPNC exhibits self-resonance near 10 MHz due to ESL. Stack the cap directly over a short ground via to minimize loop inductance. Pair this part with a smaller 1 nF–10 nF 0402 cap in parallel if you need additional impedance reduction above the self-resonant frequency. Always verify with VNA or impedance analyzer measurements on the actual PCB.
