Introduction:Metal film resistors are resistors in which special metals or alloys are used as resistance materials, and the resistance film layer is basically formed on ceramic or glass by vacuum evaporation or sputtering. This type of resistor is generally made by vacuum evaporation process, that is, heating the alloy in a vacuum, the alloy is evaporated, and a conductive metal film is formed on the surface of the porcelain rod. Grooving and changing the thickness of the metal film can control the resistance. Its heat resistance, noise potential, temperature coefficient, voltage coefficient and other electrical properties are better than carbon film resistors. Compared with carbon film resistors, this type of resistor is small in size, low in noise, and stable, but at a higher cost. It is often widely used as a precision and high-stability resistor, and it is also commonly used in various radio electronic equipment.
Features:Metal film resistance temperature coefficient is small, high precision, low noise, good high frequency performanceAmbient temperature:-55°C~+125°C The body color is sky blue,Used for current limiting or voltage division of circuits,Temperature drift 35-50PPM Tonal balance Pure copper feet Play steady
