Metal film resistors

Metal Film resistor is Film resistor (Film Resistors) of a kind.It is the high temperature vacuum coating technology will be closely attached to the porcelain nickel chromium alloy or similar bar surface skin membrane, after debugging cutting resistance, in order to achieve the final requirements precision resistance, then add appropriate joint cutting, and on its surface coated with epoxy resin sealing protection.As it is a lead resistance, it is convenient for manual installation and maintenance, and is used in most household appliances, communications, instruments and instruments.
