Metal oxide film resistors exceed the performance of metal film and carbon film for the following properties.

What is a metal oxide resistor. Metal oxide varistor mov basics of varistor a varistorvoltage dependent resistor vdr is a component which has a voltage current characteristics that is very much similar to that of a diode. Metal oxide varistors consist of approximately 90 zinc oxide as a ceramic base material plus other filler materials for the formation of junctions between the zinc oxide grains. This is then oxidised to give the metal oxide film.

A metal film resistor in which an oxide of a metal such as tin is deposited as a film onto an insulating substrate. Metal oxide film resistors must not be confused with metal oxide varistors made of zinc oxide or silicon carbide. The metal oxide resistor is typically manufactured by taking a ceramic rod which is heated then heated in a tin chloride vapour to deposit a thin layer of the metal.

Metal oxide film resistors are fixed form axial resistors. Other metal oxides may use a different process. They are made of ceramic rod that is coated with a thin film of metal oxides such as tin oxide.

Metal oxide film. This makes the conductive path longer and narrower considerably increasing he resistance. One the metal oxide layer is established the value is established by cutting a helix in the oxide using a laser.

The metal oxide varistor or mov for short is a voltage dependant resistor in which the resistance material is a metallic oxide primarily zinc oxide zno pressed into a ceramic like material.
