The CAP CER 120PF 50V C0G/NP0 1812 is a type of ceramic capacitor. It has a capacitance value of 120 picofarads and operates at a voltage rating of 50 volts. The C0G, or NP0, designation indicates that it belongs to the Ceramic Class I category, characterized by a stable capacitance and minimal temperature dependence over a wide range of temperatures. This specific capacitor is part of the 1812 package size (also known as metric 4532), which provides compact dimensions suitable for applications where space is limited.
