The resistors are made up of a resistive layer on a ceramic substrate and coated with conductive terminals at each end. The resistive layer can be made of various materials such as ruthenium oxide, nickel-chromium, or copper oxide. The substrate is usually made of aluminum oxide or silicon dioxide, which provides the base for the resistor. The surface of the resistor is then covered with a protective layer such as epoxy that separates it from the environment.
, Xieyuan Electronics offers thick film resistors with an extensive range of resistance values and tolerances to meet diverse project requirements.
