C0402C103K3RAC7867 – KEMET

Overview

The KEMET C0402C103K3RAC7867 is a 0.01 µF multilayer ceramic capacitor (MLCC) designed for general-purpose decoupling and filtering applications. Its X7R dielectric offers a stable capacitance across its operating temperature range of -55°C to +125°C, making it suitable for demanding environments. A critical design consideration for X7R dielectrics, however, is the DC bias effect, where capacitance can significantly decrease under applied voltage, necessitating careful voltage derating in circuit design to maintain nominal performance. This 0402-sized component provides a robust solution for space-constrained boards.
