Metal oxide film resistor definition
The metal oxide film resistor is a type of fixed resistor, which uses metal oxide film as the resistive element to limit the flow of electric current to certain level.
What is metal oxide?
Metal oxide is a metallic compound, which is formed because of the chemical bonding between the oxygen atom and other elements. Metallic compound consists of two or more different types of atoms such as (tin with oxygen). In metal oxide film resistors, the film is constructed by using the tin oxide.
What is tin oxide?
Tin oxide is a type of metallic compound, which is formed because of the chemical bonding between the oxygen atom and tin.
Metal oxide film resistor construction
The construction of metal oxide film resistor is almost similar to the metal film resistors. The main difference between the metal oxide film resistor and the metal film resistor is material used for constructing the film.
In metal film resistor, the film is constructed by using the metals such as nickel chromium whereas in metal oxide film resistors, the film is constructed by using the metal oxide such as tin oxide.
The metal oxide film resistor is made by coating the ceramic core with metal oxide such as tin oxide. The antimony oxide is added to the tin oxide to increase its resistivity. The resistivity of the metal oxide film is mainly depends on the amount of antimony oxide added to the tin oxide.
The film made of tin oxide and antimony oxide acts as the resistive element to the electric current. Hence, metal oxide film restricts the electric current to certain level. The ceramic core acts the insulating material to the electricity. Hence, the ceramic core does not allow heat through it. Thus, these resistors can withstand at high temperatures.
The metal end caps are fitted at both ends of the resistive element. The leads made of copper are joined at two ends of these metallic end caps. The metal oxide film resistors are able to withstand at higher temperatures than metal film and carbon film resistors.
In metal oxide film resistor, the desired resistance is achieved by cutting the metal oxide film in a helical manner along its length. Once the desired resistance value is achieved, the cutting of metal oxide film is stopped. Lasers are generally used to cut the metal oxide film in a helical manner.
Resistance of metal oxide film resistor is depends on the amount of antimony oxide added, the thickness of metal oxide film layer, and the width of helical metal oxide film cut
The resistance of the metal oxide film resistor is depends on the amount of antimony oxide added to the tin oxide, the thickness of the metal oxide film layer, and the width of helical metal oxide film cut.
