Metal film resistor metal film resistor symbol RJ as a mark Metal film resistors are one of the film resistors (Film Resistors). It uses high-temperature vacuum coating technology to closely attach nickel-chromium or similar alloys to the surface of the porcelain rod to form a film. After cutting and adjusting the resistance value to achieve the final required precision resistance value, it is then cut with appropriate joints and coated on the surface Sealed and protected by epoxy resin. Because it is a lead type resistor, it is convenient for manual installation and maintenance, and is used in most household appliances, communications, and instruments.
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. The manufacturing process of metal film resistors is relatively flexible. Not only can its material composition and film thickness be adjusted, but also the resistance value can be adjusted through grooves. Therefore, a resistor with good performance and a wide resistance range can be made. 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.
