Ceramic chip resistors with metal foil
TT Electronics’ MFC series of metal foil chip resistors are designed for current sensing duties in power electronics applications and can also be used in industrial and medical applications. The parts are ideal for power supplies, dc/dc convertors, small motor drives, actuator drives and lighting drives. The MFC resistors’ metal foil resistance material is bonded onto a 96% alumina substrate and features a protective coating that is resistant to all normal industrial cleaning solvents suitable for printed circuits. Metal foil on ceramic technology has better surge tolerance than thick-film, offering improved reliability in the presence of current surges. It also features lower self-heating than thick-film or metal strip construction thus obviating hot spots, improving both product and host equipment reliability. The resistors’ operating temperature is -55 to 155°C, and their low TCR of +/-50ppm/°C maintains accuracy over a wide range of operating currents and ambient temperatures.
