Metal Foil Resistors

These resistors are constructed with a metal foil resistive element mounted on a ceramic substrate for excellent heat conductivity. The metal foil resistive element of these current sense resistors results in very low inductance, low noise and excellent reliability. Available with very low resistance values (down to five milliohms) and ideal for current sensing in consumer and telecommunication electronics and industrial automation applications.
