What is a Metal film resistor?

A metal film resistor is a fixed resistor that uses metal as the resistor. Because it is a type of fixed resistor, it is sometimes called a metal film fixed resistor. Two types of fixed resistors are commonly and widely used: carbon resistors and metal film resistors. Carbon resistors use carbon as the resistive element, while metal film resistors use metal as the resistive element. They have higher resistance value accuracy than carbon resistors, but are more expensive.
