CL21A106KAYNNNE 概述
An MLCC, or multilayer ceramic capacitor, is a passive component built by stacking alternating thin ceramic dielectric layers and internal metal electrodes. Its primary role is to store and release electrical energy locally while suppressing high-frequency noise and supplying transient current near active circuits. In the component taxonomy, the CL21A106KAYNNNE belongs to the MLCC family, then ceramic capacitors, then capacitors, then passive components, and finally electronic components. The X5R dielectric is a Class II ceramic formulation that balances high volumetric capacitance density with acceptable temperature stability for commercial-grade designs.
Key features of the CL21A106KAYNNNE include 10 µF nominal capacitance at 25 °C and 0 V DC bias, 25 VDC rated working voltage, ±10% tolerance over the X5R temperature window, and a standard 0805 footprint measuring 2.0 mm × 1.25 mm. The 25 V rating provides useful margin on common 3.3 V, 5 V, and 12 V supply rails, although engineers must verify that DC bias does not produce unacceptable capacitance loss, the well-known Class II MLCC phenomenon called DC-bias derating.
Architecturally, the X5R dielectric uses a barium-titanate-based ceramic with EIA Class II behavior, allowing far higher capacitance density per unit volume than Class I dielectrics (NP0/C0G). The trade-off is a capacitance value that varies non-linearly with applied DC bias, AC voltage, temperature, and aging. Compared with X7R, X5R can deliver higher capacitance density in the same case, although its temperature and voltage coefficients are typically wider; compared with Y5V/Z5U, X5R offers substantially better stability across the operating envelope.
Typical applications include microcontroller and DSP power bypass, regulator output smoothing, IoT sensor nodes, mobile-device power paths, industrial control boards, and consumer-electronics filter networks. The part is particularly useful when a design needs more local energy storage than a 0402 or 0603 bypass capacitor can provide while still using a widely supported and easily sourced land pattern.
When laying out this capacitor, place it as close as possible to the power pin or signal node it serves. Use short, low-inductance traces and pair it with a smaller high-frequency bypass capacitor when wideband decoupling is required. Always verify effective capacitance under the expected DC bias, temperature, tolerance, aging, and PCB flexure conditions before finalizing the BOM.
This page synthesizes manufacturer datasheet data, current distributor pricing, drop-in same-package alternatives, and practical design notes on DC-bias derating and cross-brand substitution for engineers designing with the CL21A106KAYNNNE.

典型应用
CL21A106KAYNNNE 适用于 7 应用s: Microcontroller Power-Rail Decoupling, DC-DC Converter Output Smoothing, IoT Sensor Node Power Filter, USB Power-Path Bulk Filter, Industrial Control Board Power Filtering, Audio Codec Reference Supply Filter, Automotive Infotainment Auxiliary Power Filter.
Microcontroller Power-Rail Decoupling
The CL21A106KAYNNNE's 10 µF X5R bulk storage makes it a strong choice for placing adjacent to a microcontroller's VDD pin. Effective capacitance stays roughly 60-80% of nameplate at the typical 3.3 V core rail, which is enough to handle the microamp-to-millamp load-step surges during sleep-wake transitions of low-power MCUs. Because the part is 2.0 mm × 1.25 mm, it fits below a standard SOIC footprint and pairs naturally with a 100 nF 0402 for high-frequency decoupling.
推荐
DC-DC Converter Output Smoothing
Placed at the output of a buck or LDO regulator, the CL21A106KAYNNNE supplies transient current during load steps and smooths the switching ripple to within the regulator's bandwidth. The 25 V rating comfortably covers outputs up to roughly 12 V, with margins for ringing. Engineers should select X5R over X7R here when they prioritize volumetric capacitance density over temperature drift, and should verify effective capacitance under the worst-case load step.
推荐
IoT Sensor Node Power Filter
Battery-powered IoT sensors benefit from the CL21A106KAYNNNE's combination of small footprint and 10 µF storage, which helps stabilize the supply of a low-power radio or sensor front-end during transmit bursts. The X5R characteristic maintains acceptable capacitance across the −20 °C to +60 °C operating envelope typical of consumer IoT, and the lead-free termination supports standard 260 °C reflow profiles used on wireless modules. Designers should account for 40-50% DC-bias loss at the lowest expected battery voltage.
推荐
USB Power-Path Bulk Filter
Inside a USB-powered product, the CL21A106KAYNNNE serves as a bulk filter on the VBUS rail, absorbing the surge currents from hot-plug events and protecting downstream regulators from supply droop. The 25 V rating is well above the 5 V nominal VBUS, providing margin for cable-inductance transients that can spike above 10 V during plug events. Pair it with a TVS diode for ESD protection and a ferrite bead for radiated emissions compliance.
推荐
Industrial Control Board Power Filtering
On an industrial PLC or motor-control board, the CL21A106KAYNNNE can be used as a general-purpose filter on 24 V and 12 V rails (derated to 80% per common industrial standards). Its 25 V rating covers 12 V rails directly, and 24 V rails with proper transient suppression upstream. The 0805 case is widely accepted on industrial SMT lines, and Samsung EM's manufacturing scale ensures long-term availability for multi-year production runs.
推荐
Audio Codec Reference Supply Filter
Although the CL21A106KAYNNNE is an X5R (not C0G/NP0), it can be used to filter bulk energy on analog supply pins of audio codecs where high current reserve matters more than absolute noise floor. Place it on the AVDD pin of an audio DAC, then add a 10 µF C0G/NP0 (or a smaller LDO) immediately after for low-noise regulation. The combination provides instantaneous energy plus a clean reference voltage for the audio front-end.
推荐
Automotive Infotainment Auxiliary Power Filter
Inside automotive infotainment head units and instrument clusters, the CL21A106KAYNNNE can serve as bulk filtering for 5 V and 12 V rails derived from the vehicle's 13.8 V bus. For AEC-Q100-qualified automotive projects, prefer the TDK CGA4J3X5R1E106K125AB or another automotive-grade X5R 0805; for non-safety-related consumer infotainment zones, the standard CL21A106KAYNNNE typically delivers adequate reliability at the rated temperature range.

- 25 V rating provides comfortable derating margin on 12 V rails （对比 CL10B106MQ8NRNC (6.3 V))

设计说明
Class II X5R MLCCs lose effective capacitance under DC bias; at the 25 V rating on a 12 V rail the CL21A106KAYNNNE typically retains about 70-80% of nameplate, but at higher proportions of rated voltage the loss can reach 40-50%. Always check the manufacturer's DC-bias characterization graph rather than trusting the 10 µF number on the BOM line. If effective in-circuit capacitance matters, consider a 50 V rated part or a larger 1206 case.
Place the CL21A106KAYNNNE within 2-3 mm of the supply pin it is decoupling, with the shortest possible traces to the bypass node and ground return. Use the IPC-7351 land pattern for nominal 0805 (pad size approximately 1.4 mm × 1.0 mm with 0.5 mm x-axis and 0.3 mm y-axis extension) to ensure robust solder fillets. Pair the 10 µF bulk with a 100 nF 0402 high-frequency bypass cap on the same supply pin for wideband decoupling.
MLCCs in 0805 cases are sensitive to thermal gradients and mechanical flexure, which can lead to cracking during solder reflow or PCB depanelization. Follow the manufacturer's reflow profile (peak 260 °C, 30 s above 250 °C per JEDEC J-STD-020) and avoid placing the part near high-flexure zones such as screw holes or board edges. If mechanical stress is a concern, specify a soft-termination variant or use a smaller case size.
Avoid using Class II X5R MLCCs in timing-critical or analog-precision signal-path circuits (e.g., RC filters, sample-and-hold) where the dielectric's voltage and temperature drift would introduce unacceptable error. For those applications, choose Class I NP0/C0G dielectrics (e.g., a 100 nF C0G 0402). The CL21A106KAYNNNE is intended for bulk energy storage and decoupling, not for precision filtering or timing references.
