Current-Sensing Resistor Values Go Down To 0.25 mOhm

The CSS/CSSH current-sensing resistors offer values down to 0.25 milliohms in a standard surface-mounted chip package. This resistor series is rated for full-power operation at up to 100°C, and has an operating temperature range of up to 275°C. Available package sizes include 1206, 2010, 2512, 2725, and 2728. Temperature coefficient of resistance (TCR) values range from 15 ppm to 50 ppm with tolerances as low as 0.5%. This series is capable of 3 W in a 2512 size chip, and offers a 4-W power rating for the 2725 and 2728 chip sizes. Target applications include laptops, portable test equipment, bar code scanners, medical monitoring and diagnostic equipment, communications equipment, metering equipment, and motion controls and instrumentation. The CSS / CSSH Series is available in standard 7-in. tape-and-reel packaging. Pricing varies widely with size, resistance value, and tolerance, and ranges from $0.175 to $0.50 each in full-reel quantities. STACKPOLE ELECTRONICS INC., Raleigh, NC. (888) 734-7347.
