Tips: How do metal film resistors work?
When an electric current flows through a metal film resistor, it encounters resistance. The metal film's resistance property is determined by its length, width, thickness, and the resistivity of the metal used. As the current passes through the resistive path, it experiences a voltage drop proportional to the resistance value of the resistor, according to Ohm's Law (V = IR). The metal film's resistance value remains relatively stable across a wide range of operating conditions.
Metal film resistors are known for their accuracy, stability, and low noise characteristics. The thin metal film allows for precise resistance values and better temperature coefficients compared to other resistor types. These properties make them suitable for applications where precise resistance values, low noise generation, and temperature stability are essential, such as in analog circuits, audio equipment, and precision measurement devices.
