The Function and Applications of Metal Glazed Film Resistors

Metal glazed film resistors are electronic components that are used to control the flow of electric current in a circuit. They are made of a resistive material that is coated with a thin layer of metal oxide, which gives them their distinctive glazed appearance. In this article, we will discuss the function and applications of metal glazed film resistors.

Function of Metal Glazed Film Resistors

The primary function of metal glazed film resistors is to provide a precise amount of resistance to the flow of electric current in a circuit. They are used to limit current flow, divide voltages, and stabilize circuit operation. Metal glazed film resistors achieve this by converting electric energy into heat energy, dissipating it into the surrounding environment.

Metal glazed film resistors have a low temperature coefficient, which means that their resistance value does not change significantly with temperature fluctuations. This makes them ideal for use in applications where precise resistance values are required, such as in audio and video equipment, instrumentation, and telecommunication systems.
