The CC0805JRNPO9BN180 is a Multi-Layer Ceramic Capacitor (MLCC) manufactured by Yageo. It is an SMD/SMT component with a package size of 0805, a capacitance of 18pF, a maximum voltage of 50V, and a tolerance of 5%. It is a NPO (Negative Positive Over) capacitor, meaning it varies very little from its nominal capacitance value through a wide range of temperatures, frequencies, and environmental conditions. The part is lead-free, RoHS compliant, and halogen-free.
