    Metal film resistor applications

    Tips: What is a metal film resistor?

    A metal film resistor is a type of electrical resistor commonly used in electronic circuits. It is constructed by depositing a thin film of metal, typically nickel-chromium or tin oxide, onto a ceramic substrate. The metal film provides the resistive element of the resistor.

    The metal film resistor offers several advantages over other types of resistors. It has excellent stability, providing consistent resistance values over time and temperature changes. The thin film also results in low noise and low inductance, making it suitable for applications where precision and accuracy are important.
