Metal-oxide film resistors are fixed form, axial resistors. They are made of ceramic rod that is coated with a thin film of metal oxides, such as tin oxide. Metal oxide film resistors must not be confused with metal oxide varistors, made of zinc oxide or silicon carbide.
Construction
The metal oxide film is mostly produced with chemical deposition methods. Almost always a ceramic carrier is used as substrate.
