The CC0402JRNPO9BN180 is a multilayer ceramic capacitor (MLCC) manufactured by Yageo. It is an SMD/SMT (surface mount device/surface mount technology) component and has 18pF capacitance with a 50V voltage rating and 5% tolerance. The NPO (Negative Positively Offset) dielectric is made of ceramic and provides excellent temperature stability, high volumetric efficiency, and low ESR (Equivalent Series Resistance). It is ideal for high frequency, switching, memory decoupling, filtering, RFI/EMI, and timing applications.
