They are commonly found in amplifier circuits, power supplies, instrumentation, and other electronic systems where precise and stable resistance values are required.

Tips: Can metal film resistors be used in both AC and DC circuits?

Metal film resistors can indeed be used in both AC (alternating current) and DC (direct current) circuits. The primary function of a resistor is to impede the flow of current and create a voltage drop. Whether the current is AC or DC, the resistor's role remains the same.

Metal film resistors are a common type of resistor that is suitable for a wide range of applications. They are known for their stability, accuracy, and low noise characteristics. These resistors are typically made by depositing a thin film of metal alloy onto a ceramic substrate. The metal film provides the resistance value and determines the resistor's properties.

In both AC and DC circuits, metal film resistors can handle the flow of current and dissipate power as heat. However, it's important to consider the specific requirements of the circuit when selecting a resistor. Factors such as power rating, tolerance, and temperature coefficient should be taken into account to ensure proper functioning and reliability in the given application.
