Carbon Film Resistors RT function and uses inexpensive stand cement resistance, widely used in various electronic products. Good stability characteristics, was not a negative temperature coefficient, by the voltage and frequency is small, the pulse load stability. The main parameters RJ metal film resistor can be used to require high accuracy, good temperature stability of the circuit, or circuit requires strict teaching situations, such as the op amp input terminal matching resistance. Temperature coefficient, voltage coefficient, thermal performance and noise performance are not carbon film resistors, small size, high accuracy; but the pulse load stability is poor, the price is more expensive than carbon film resistors. It can be used to require high precision cement resistance, temperature stable circuit Guangzhou cement resistance, or circuit requires strict occasions teach cement resistance standards, such as the op amp input terminal matching resistance and high temperature applications. Low price, performance metal film resistors basically the same, a higher price, heat resistance, extreme temperature up to 240 ℃. Metal film resistors metal film resistors under vacuum conditions, depositing a layer of the ceramic substrate made of an alloy powder. By changing the length of the metal film thickness or get a different resistance. Metal film resistors are metal film resistors (CN) metal oxide film resistors (RS) and metal glaze film resistors (RK). Since the metal film resistors power, low noise, low temperature coefficient, high accuracy, good high-frequency characteristics, a wide range of resistance, etc., it is widely used in advanced audio, computers, test equipment, automation control and other high-end devices.
