Vishay Intertechnology has announced a new high-temperature 1W surface-mount Power Metal Strip resistor that is said to be the industry's first current sensing resistor in the 2010 case size to operate over a temperature range of –65°C to +275°C. The WSLT2010...18 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 high-temperature capability and high power ratings (double the standard WSL rating) of the WSLT2010...18 allow it 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 WSLT2010...18 will be designed includes automotive engine and transmission controls, audio 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 WSLT2010...18 features all-welded construction with a solid metal nickel-chrome alloy resistive element with low TCR of < 20 PPM/°C. The resistor offers low inductance values, an excellent frequency response to 50 MHz, and low thermal EMF of less than 3 µV/°C.
