Metal Oxide

Overview

Metal Oxide Resistors

Metal Oxide Resistors belong to the family of fixed form axial resistors similar to Metal film resistors and Carbon film resistors. Instead of a metal film , these resistors use a metal oxide resistance material that is coated on top of a ceramic substrate. Read More

They are specifically suited for high endurance applications because they are better at surge and overload handling, higher voltage and power rating and are also more stable at higher temperatures. However, these resistors are not very good in low resistance and tolerance applications. Metal Oxide Resistors also have a higher temperature coefficient of resistance than metal and carbon film resistors.

Tin oxide mixed with antimony oxide is the most popular material used in these resistors. The resistance value depends on the amount of oxide material, the thickness of the metal oxide coated and also the dimensions (length and width) of the metal-oxide film cut. The oxide films are cut accurately using laser beams.

Manufacture of metal oxide resistors are more complicated than either carbon or metal film resistors.

Metal oxide resistors find application in:

  • Telecommunication
  • Medical Equipment
