C0402C224M9PACTU Обзор
A multilayer ceramic capacitor (MLCC) is a passive surface-mount component consisting of alternating layers of ceramic dielectric and metal electrodes fired into a monolithic block. The X5R dielectric is a Class II (mid-K) formulation that offers higher capacitance per volume than Class I (C0G/NP0) dielectrics, at the cost of greater capacitance change with temperature, DC bias, and aging. X5R parts are typically specified for -55C to +85C with +/-15% maximum capacitance variation across that range. This places X5R firmly in the decoupling, bypass, and general-purpose filtering role rather than precision timing or filter applications.
Key features include 0.22 uF nominal capacitance in a 0402 footprint, 6.3 V DC rated voltage, +/-20% tolerance, X5R temperature characteristic (EIA code 2), and a lead-free (Sn) matte tin termination that is RoHS compliant. The part uses KEMET's commercial-grade SMD Comm X5R series and is qualified to 85C continuous operation. KEMET's Flex Termination option (the FT suffix found on similar parts) is NOT present on this -TU variant, which uses a standard tin termination suitable for reflow soldering on standard ENIG or tin-pad surfaces.
The C0402C224M9PACTU is most commonly used to decouple low-voltage digital ICs such as microcontrollers, FPGAs, ASICs, and DSPs that operate from 1.8 V, 2.5 V, 3.3 V, or 5 V rails. With 0.22 uF of bulk storage in a 0402 footprint, it complements 0.1 uF and 1 nF capacitors that handle higher-frequency noise, while its small size preserves routing channels in dense BGA and QFN layouts. X5R parts exhibit significant DC-bias derating; at 5 V applied the actual capacitance may be 30-50% lower than the nominal 0.22 uF, which should be considered when sizing hold-up time or filter cutoffs.
Typical applications include microcontroller bypass on 3.3 V rails, decoupling for low-power wireless SoCs, bulk filtering on USB data lines, and general-purpose coupling capacitors in audio and signal-chain PCBs. The 0402 size supports hand-rework and visual inspection in prototypes while still being compatible with high-volume pick-and-place assembly.
When designing with this part, account for X5R DC-bias derating: at the rated 6.3 V the real capacitance can drop substantially versus the 0.22 uF nominal, so verify effective capacitance with KEMET's K-SIM tool or the manufacturer SPICE model. Place the capacitor as close to the IC power pin as possible, and pair it with a smaller 0.01 uF or 0.1 uF cap to cover high-frequency noise that X5R cannot effectively suppress above its self-resonance.

Типичное применение
C0402C224M9PACTU подходит для 6 применениеs: Microcontroller 3.3V Decoupling, USB 2.0 Data Line Coupling, Low-Power Wireless SoC Bulk Decoupling, Sensor Power-Rail Filtering, FPGA / CPLD Bank Supply Decoupling, Audio Codec Analog Supply Bypass.
Microcontroller 3.3V Decoupling
The C0402C224M9PACTU's 0.22 uF bulk capacitance in a 0402 footprint makes it a standard bulk-decoupling cap on 3.3V rails for ARM Cortex-M microcontrollers. Its 6.3V rating provides a 1.9x safety margin over the 3.3V supply, and the 1.0 x 0.5 mm 0402 case fits between IC power pins and ground vias on dense STM32, ATSAM, and PIC32 layouts. Typical placement: 1-2 mm from the MCU VDD pin, paired with a 0.1 uF cap for high-frequency noise. X5R DC-bias loss is acceptable for supply-noise suppression because the controller tolerates +/-50% effective capacitance on the bulk capacitor.

USB 2.0 Data Line Coupling
The C0402C224M9PACTU's 0.22 uF capacitance in a 0402 package is commonly used for AC coupling on USB D+/D- data lines in USB 2.0 devices, where it blocks DC bias while passing high-speed data up to 480 Mbps. Its 6.3V rating easily handles the 3.3V common-mode voltage on the data lines, and the 0402 case enables placement adjacent to the USB connector pins or the transceiver IC. The X5R dielectric has acceptable phase performance for USB 2.0; for USB 3.0/3.1 signaling above 5 GHz a tighter C0G part is recommended instead.

Low-Power Wireless SoC Bulk Decoupling
In BLE, Wi-Fi, and sub-GHz wireless designs based on SoCs such as Nordic nRF52, ESP32, and TI CC2640, the C0402C224M9PACTU serves as a bulk-decoupling cap on the 1.8V or 3.3V core supply rails. The 0402 footprint and 0.5 mm thickness fit underneath or beside the wireless module, and the 6.3V rating covers the typical 1.8V-3.6V Li-ion battery range with margin. Designers pair it with a 0.1 uF cap closer to the RF PA supply pin, using the 0.22 uF bulk cap to suppress low-frequency load transients during transmit bursts up to 100 mA.
Рекомендуется
Sensor Power-Rail Filtering
The C0402C224M9PACTU is commonly deployed as a power-rail filter cap for MEMS sensors (accelerometers, gyros, pressure sensors) and analog sensor front-ends operating from 1.8V-3.3V rails. The 0.22 uF capacitance provides low-impedance supply paths that reduce sensor noise coupling from digital logic, and the 0402 case allows placement directly under the sensor QFN/DFN package. For high-precision analog sensor chains, X7R variants are sometimes preferred, but X5R is acceptable for consumer-grade MEMS sensor supplies where absolute noise is dominated by the sensor itself.

FPGA / CPLD Bank Supply Decoupling
Modern FPGA and CPLD designs using low-core-voltage parts such as Lattice ECP5, Xilinx Spartan-7, and Altera MAX 10 benefit from multiple 0.22 uF 0402 caps placed adjacent to each bank-supply pin. The C0402C224M9PACTU fits this role on 1.2V, 1.8V, 2.5V, and 3.3V bank rails with its 6.3V rating, and the small 0402 footprint preserves routing channels between BGA fanout vias. Designers typically place one 0.22 uF cap per bank, supplemented by smaller 0.1 uF and 0.01 uF caps for high-frequency decoupling on each supply pin.
Рекомендуется
Audio Codec Analog Supply Bypass
In audio codec and headphone amplifier designs, the C0402C224M9PACTU provides bulk bypass on the analog 3.3V AVDD rail. The 0.22 uF capacitance reduces ripple from upstream switching regulators that can couple into the audio output, and the 0402 footprint supports dense layouts where multiple analog supply pins surround a QFN audio codec. X5R's +/-15% temperature variation is acceptable for audio supplies because the human ear is far less sensitive to mid-frequency supply noise than to audio-band signal artifacts. For premium audio paths, designers add a 10 uF tantalum or polymer cap in parallel.

Заметки по проектированию
X5R dielectric exhibits significant DC-bias derating: at 3.3V applied, the effective capacitance of C0402C224M9PACTU can drop to roughly 0.10-0.15 uF rather than the nominal 0.22 uF. Verify with KEMET's K-SIM SPICE tool or the manufacturer DC-bias chart before finalizing filter designs that depend on absolute capacitance. For sub-1.8V applications this derating is minimal; for 5V designs consider stepping up to a 10V-rated X5R or moving to X7R dielectric.
Place the C0402C224M9PACTU within 1-2 mm of the IC power pin, with the ground pad tied to a low-impedance ground via within 1 mm. Recommended land pattern follows IPC-7351 nominal 0402: 0.5 mm x 0.5 mm pads with 0.6 mm pitch. Use a microvia-in-pad construction if placing the cap directly under a QFN/DFN package. Avoid running signal traces between the cap and the IC pin, which adds parasitic inductance and degrades decoupling effectiveness above 50 MHz.
The self-resonant frequency (SRF) of the C0402C224M9PACTU is approximately 20-30 MHz, above which the cap behaves inductively. For high-speed digital decoupling (DDR, USB 3.0, RF), pair the 0.22 uF bulk cap with smaller 0.1 uF and 0.01 uF capacitors in a staircase pattern so the combined impedance stays low from DC through 1 GHz. The 0.22 uF cap effectively suppresses load transients in the 1-100 MHz band; smaller values cover the upper harmonics.
