Vishay Intertechnology, Inc. announced a new high-temperature 1-W surface-mount Power Metal Strip resistor that is the industry's first current sensing resistor in the 2512 case size to operate in a temperature range of 65 C to +275 C. The WSLT2512 resistor features a very low 10-mΩ to 500-mΩ resistance value range, a tight tolerance down to 0.5 %, and low TCR values down to 75 ppm/C.

The temperature range of the WSLT2512 allows it to replace larger current sensing resistors with a similar +275 C maximum operating temperature. Its robust specifications allow the WSLT2512 to be used for current sensing and pulse applications in harsh, high-temperature environments without sacrificing power rating or electrical performance. The range of systems into which the WSLT2512 will be designed includes automotive engine controls, safety controls, multi-media electronics, climate controls, and anti-lock brakes; and industrial oil/gas well drilling, including down hole test/measurement equipment.

Manufactured using proprietary techniques that result in extremely low resistance values, the WSLT2512 features all-welded construction with a solid metal nickel-chrome alloy resistive element. The resistor offers low inductance values, an excellent frequency response to 50 MHz, and low thermal EMF of less than 3 V/C.

Samples and production quantities of the new resistor are available now, with a lead time of four to six weeks for larger orders.
