Metal film resistors have a thin metal layer as resistive element on a non-conducting body. They are amongst the most common types of axial resistors. Other film type resistors are carbon film and thick and thin film resistors. In most literature referrals to metal film, usually it is a cylindrical axial resistor. However, thin film chip resistors use the same manufacturing principle for the metal layer. The appearance of metal film resistors is similar to carbon film resistors, but their properties for stability, accuracy and reliability are considerably better.
Metal film resistors are axial resistors with a thin metal film as resistive element. The thin film is deposited on usually a ceramic body.
Typical applications:
Metal film resistors are precise and functional resistors, suitable for applications on precise electronic circuits, have good characteristics for tolerance, stability and TCR. Furthermore, the resistors feature low noise properties and a high linearity because of a low voltage coefficient. Therefore, in circuits where tight tolerance, low temperature coefficient and low noise properties are important, often metal film resistors are used. Examples of applications are active filters or bridge circuits.
Reliability of metal film resistors:
For a good reliability, metal film resistors are normally operated between 20 and 80 percent of their specified power rating. Reliability is generally increased by derating 50%. However, in very specific situations, at lower than 20% of the power rating in a humid environment the reliability decreases. Compared to wirewound or carbon composition resistors, these resistors are easier damaged by voltage surges and power overloads.
