The CSS series is an ultra-low resistance (< 2 m?), surface-mount metal strip resistor rated for 45 A of current at 1 W, while exhibiting low inductance and low TCRs. The resistor is offered in a two terminal design and a four terminal Kelvin design, with a resistance offering of 0.0005 to 0.002 ?. The resistors are used in applications requiring precision current-sensing and power management circuits in computers, power supplies, and motor control circuitry where current-sense devices are used. Rated for a full 1 W @ 70ºC, the resistors feature resistance values as low as 0.0005 to 0.003 ?, in tolerances of 1, 3, and 5 percent, with TCRs as low as ±20 ppm/ºC. The units are rated for operation from -40°C to +125ºC. IRC Inc.
