CC0402GRNPO9BN180 is a Yageo Multilayer Ceramic Capacitor (MLCC) SMD/SMT 18pF 50V NPO 2% manufactured by Yageo. It is a small, surface-mounted component used for bypass and coupling applications in which the capacitance is needed but low voltage is not necessary. The capacitor is constructed with multiple layers of ceramic dielectric material, as well as two plates for the plates. The size is 0402, and its tolerance should be within 2 percent. The capacitance rating is 18pF, and the voltage rating is 50V. It is lead free, RoHS compliant, and suitable for BGA, LGA, and 0.5mm pitch applications.
