Vishay’s New WSLS2512 Surface-Mount Power Metal Strip® Resistor Offers Increased Stability With Low Resistance Change of 0.5 % in Low Resistance Values of 0.01 Ω to 0.1 Ω
MALVERN, PENNSYLVANIA — January 19, 2007 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new surface-mount Power Metal Strip® resistor that offers improved resistance stability during operation with a maximum resistance change of 0.5 % through a 2000-hour workload. By comparison, the typical current sensing resistor has a resistance stability of ≥1 % through a 1000-hour workload.
The Vishay Dale WSLS2512 devices feature specially selected materials which allow for current sensing in high-temperature (+125 °C), tightened-stability applications that require precision current monitoring of sensitive circuits, such as automotive electronic controls including engine, transmission, and pollution controls.
Manufactured using proprietary techniques that result in extremely low resistance values of 0.01 Ω to 0.1 Ω, the WSLS2512 features all-welded construction with a solid metal nickel-chrome alloy resistive element. The resistor offers low inductance values of 0.5 nH to 2.0 nH, a tight tolerance down to ±0.5 %, and low TCR values down to ±30 ppm/°C.
Samples of the new resistor will be available in February 2007. Production quantities will be available in Q3 2007, with a lead time of eight weeks for larger orders.
