RALEIGH, NC (Feb. 5, 2009) – Stackpole Electronics, Inc. today announced the release of their new CSS / CSSH series of ultra-stable metal element current sense chip resistors. This series utilizes unique manufacturing processes and a special resistive alloy to provide tight tolerances, low TCR’s and high power ratings. Another outstanding feature of the CSS / CSSH is the capability to handle full rated power up to 100C and the ability to operate at temperatures up to 275C. These improvements allow design engineers more accurate control of their power systems, and the ability to downsize their designs or lower board temperatures.

The CSS / CSSH series is available in sizes from 1206 up to 2728 and power ratings from 0.5 up to 4 watts. This series offers a 3 watt 2512 size chip and offers a 4 watt device in a 2725 or 2728 package depending on resistance value. The all metal construction eliminates the issue of part or solder joint cracking which might normally be a concern for larger chip sizes. This series is capable of resistance tolerances down to 0.5% and TCR’s down to 15 ppm. This ensures precise power management over a wide range of ambient temperatures.

The CSS / CSSH series is available in standard 7 inch reels and is RoHS compliant. Common values in the 4 Watt size are available at Digi-key: http://media.digikey.com/pdf/Data%20Sheets/Stackpole%20Electronics%20PDFs/CSS,CSSH%20Series.pdf. Pricing varies with size and tolerance, but generally ranges from $0.40 each to $0.70 in full reel quantities. Contact Stackpole for volume pricing.
