Stackpole Releases CSS/CSSH Series For Applications With Harsh Environmental Conditions & High Temperatures

According to Stackpole Electronics Inc., many types of motor controls and industrial power supplies have environments that most SMD current sense resistors simply can’t handle. The company states that its CSS/CSSH series offers a unique metal plate technology to allow operation up to 275°C where most other SMD current sense resistors are limited to only 155 to 170°C. In addition, the CSS/CSSH series is the first current sensing chip series that is rated for full power operation up to 100°C instead of 70°C. This allows engineers to use smaller chip sizes for their application, or keep the same size part and reduce the overall heat generated by the power circuit.

The CSS/CSSH series is available in chip sizes 1206 - 0.5W, 2010 - 1W, 2512 - 2 and 3W, 2725 - 4W, and 2728 - 3 and 4W. TCR’s range from 15 to 50 ppm and tolerances down to 0.5% are available as standard product. This series is available in 7" reels with embossed tape and quantities of 1000 or 2000 pieces depending on size.

Pricing varies with size, tolerance, and resistance value and ranges from $0.175 each to $0.50 each in full reel quantities.
