New Current Sense Resistor from Stackpole Electronics, Inc. Capable Of Handling High Current To 63 Amps

RALEIGH, NC (December 3, 2004) - Stackpole Electronics, Inc. has introduced a new current sense chip resistor capable of withstanding currents to 63 amps in a 2512 size package.

Designated the CSRL2, it is rated to 2 Watts @ 70°C and has resistance values as low as .0005 ohm, in tolerances to 1%. The CSRL2 exhibits extremely low inductance of less than 0.2nH, and has TCRs of less than +/- 100ppm/°C. The CSRL2 is rated for operation from temperatures of -55°C to 150°C.

Regarding the launch of the CSRL2, Rob Hudspeth, Director of Sales & Marketing for Stackpole commented, "We are able to withstand higher operating currents because of improvements in our materials process," he explained. "The CSRL2 provides designers of portable electronic equipment a new alternative in reliable, ultra-low resistance and very high current resistor options."

Hudspeth added, "due to a combination of higher-speed processing requirements, ever increasing space limitations, and more efficient battery management for portable electronics, engineers must be more creative in using higher current, multiple-phase circuitry. The CSRL2 is ideal for these requirements."

In addition to portable electronics devices, CSRL2 is finding application in current-sensing and feedback circuits in disk drives, power supplies, automotive systems and instrumentation.

The CSRL2 is typically priced at approximately $0.25 in quantities of 5,000, with delivery times from stock to 6 weeks.
