Vishay's Surface-Mount 2010 Power Metal Strip Resistor
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 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.
