Metal glass glaze film resistor, 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, then add appropriate joints and cut it. The surface is coated with epoxy resin for sealing protection. Because it is a lead type resistor, it is convenient for manual installation and maintenance. It has high precision, stable performance, simple and lightweight structure, good waterproof performance, and is suitable for automatic plug-ins. Metal glass glaze film resistors play an indispensable role in the electronic industry and military and aerospace fields under high-precision requirements, and are also commonly used in various radio electronic equipment.
