The capacitors are a type of component that stores electrical energy in the form of an electric field. The CAP CER 10PF 50V R2H AXIAL is a specific type of capacitor with certain characteristics. It has a capacitance value of 10 pF, which means it can store a relatively small amount of charge. Additionally, it operates within a voltage range of 50 volts and features an axial lead configuration. This particular component falls under the category of ceramic capacitors, denoted by the prefix "CER" in its designation.
