Metal film resistors are electronic components that provide resistance in a circuit. They are made by depositing a thin layer of metal onto a ceramic substrate, which allows for precise resistance values and stable performance. These resistors are known for their low noise and high accuracy, making them ideal for applications in audio equipment and precision measurement devices. One of the key advantages of metal film resistors is their temperature stability. They maintain their resistance value over a wide range of temperatures, which is crucial for reliable operation in various environments. Additionally, they have a low temperature coefficient, meaning their resistance changes very little with temperature fluctuations.
