Overview

The Kemet C0402C225M9PAC7867 is a surface-mount multilayer ceramic capacitor (MLCC) in the compact 0402 (1005 metric) package. As a general-purpose ceramic capacitor, it is typically used for high-density decoupling, bypassing, and signal coupling in digital and analog circuits. Devices in this Kemet series are designed for stable performance over a wide frequency range, low ESR, and suitability for automated assembly in consumer, industrial, computing, and communications equipment. Exact capacitance, voltage rating, dielectric type, and tolerance should be confirmed from the device datasheet for final design-in decisions.

Applications

• Local decoupling and bulk bypassing on microcontrollers, FPGAs, and DSP power rails
• High-density filtering in smartphones, tablets, and other portable consumer electronics
• Signal coupling and AC blocking in RF, IF, and high-speed communication circuits
• Noise suppression and transient filtering in industrial control and automation PCBs
• Power supply output smoothing in DC-DC converters and point-of-load regulators
• General-purpose timing, filtering, and biasing networks in measuring and test instruments

Alternatives & Replacement

Depending on stock availability, lifecycle status, and detailed electrical requirements (capacitance, voltage rating, dielectric class, tolerance, temperature characteristics), designers may need to consider compatible alternative MLCCs from other series or manufacturers.

Engineering note: When selecting a replacement, always verify the mechanical size (0402 footprint compatibility), pad layout, capacitance value, voltage rating, dielectric type (e.g., C0G, X7R, etc.), tolerance, temperature range, and DC bias behavior. Even if the case code matches, differences in derating, reliability, or electrical performance may require schematic or PCB layout changes and full validation in the target application.
