3.3R 0hm 1W 150V Metal Film Resistor is one of the film resistors. It uses high-temperature vacuum coating technology to closely adhere nickel-chromium or similar alloys to the surface of the porcelain rod to form a film, and then cuts and adjusts the resistance value to achieve the final required precision resistance value, and then adds appropriate joints to cut and coat the surface. Sealed with epoxy resin. It has high precision, stable performance, and a simple and lightweight structure. Play a non-negligible role in hash board maintenance.
