Metal film resistors are resistors that use special metals or alloys as resistance materials. They use high-temperature vacuum coating technology to heat the alloy in a vacuum, evaporate the alloy, and form a resistance film layer on a ceramic or glass substrate. The resistance can be controlled by notching grooves and changing the thickness of the metal film. Compared with carbon film resistors, metal film resistors have small size, low noise, and better temperature coefficient and voltage coefficient, but the cost is higher. Common metal film resistors are pin-type and chip-type. Among them, chip-type metal film resistors are more common with wafer resistors. Wafer resistors combine the advantages of pin-type and chip-type resistors and are small in size, allowing for small sizes. higher power.
