Product Introduction:CC0603KRX7R9BB202 Product Introduction

The CC0603KRX7R9BB202 is a Yageo multilayer ceramic capacitor utilizing X7R dielectric material, offering 2.2 nF capacitance at 50V rating with ±10% tolerance in a standard 0603 (1608 metric) surface-mount package. X7R dielectric provides a Class II temperature-stable characteristic with capacitance variation limited to ±15% over the -55°C to +125°C operating range. The capacitor features low ESR and high insulation resistance (10 GΩ minimum), making it effective for decoupling, bypass, and filtering applications across consumer, industrial, and communication electronics.

Working Principle:CC0603KRX7R9BB202 Working Principle

The CC0603KRX7R9BB202 operates as a passive energy storage element based on the principle of parallel-plate capacitance. Multiple interleaved inner electrodes within the ceramic dielectric create a high capacitance per unit volume. X7R dielectric (Class II barium titanate-based) provides moderate temperature stability while achieving higher volumetric efficiency than C0G/NP0 types. In decoupling applications, the capacitor stores charge locally near IC power pins, providing instantaneous current during transients while its low ESR and ESL suppress high-frequency noise on power rails.
