Stackpole adds 3.5-W current-sense chip resistor

Stackpole Electronics has expanded its CSRT family with the introduction of the high-power CSRT2512-UP current-sense chip resistor for applications that require high sensing precision and high power where the temperature coefficient of resistance (TCR) is more important than low resistance values. The CSRT2512-UP offers 3.5 W in a package size that typically only allows for one or two watts, said the company.

Key specs of the CSRT2512-UP current-sense chip resistor include a 50-ppm TCR in resistance values from 50 milliohm up to 33 ohms and absolute resistance tolerances as low as 0.5%. The metal film element is said to offer excellent environmental stability as well as very low resistance shift over a range of industry-standard performance tests such as load life, biased humidity, and short time overload.

The electrical and environmental stability of the CSRT make it well suited for a range of consumer electronics, computer and telecom equipment, measurement systems, battery power management, motor controls, and high-end power supplies.

Pricing for the CSRT2512-UP ranges from $0.20 to $0.25 each in full package quantities, depending on resistance value and tolerance.

Earlier this year, Stackpole introduced its CSRT thin-film current-sense resistor in an 0201 package with TCRs as low as 50 ppm.
