Metal film resistor is a resistor that sprays a metal film onto a ceramic substrate and then cuts it into a spiral. SMD metal film precision resistor (full English name: Metal Film Precision Resistor), that is, metal film resistor is also called wafer resistor in China due to its cylindrical shape without leads. The length, thickness and width of the metal helix determine the precise resistance value. Metal film resistors provide more accurate resistance values than other types of film resistors (carbon film resistors). Like carbon film resistors, metal film resistors are little affected by temperature changes and aging. They also make little noise inside. In terms of overall performance, metal film resistor is the best type, followed by carbon film resistor, followed by carbon composite resistor.
