New Vishay Intertechnology 6 W WSLF2512 Power Metal Strip« Resistor Saves Space While Increasing Accuracy and Efficiency
Device Combines High Power Density With Low Resistance and TCR
MALVERN, Pa. — November 9, 2016 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new surface-mount Power Metal Strip« current sense resistor that combines a high power rating up to 6 W, TCR down to ▒ 70 ppm/░, and extremely low resistance values down to 0.0003 Ω in the 2512 case size.
Providing a power density of 192 W/in^2, the Vishay Dale WSLF2512 allows designers to save board space in high-power circuits by utilizing the smallest resistor possible. The device’s low TCR provides stable and accurate current measurement across a wide temperature range, while its low resistance values minimize power losses and improve end product efficiency.
The WSLF2512’s advanced construction incorporates a solid metal nickel-chrome, manganese-copper, or manganese-copper-tin alloy resistive element with low TCR (< 20 ppm/░C). This results in a higher-power resistor in a smaller size that maintains the superior electrical characteristics of the Power Metal Strip construction. A proprietary processing technique produces resistance values ranging from 0.0003 Ω to 0.003 Ω, with tolerances of ▒ 1.0 % and ▒ 5.0 %. The device provides low thermal EMF (< 3 ÁV/░C), very low inductance (< 2 nH), and a temperature range from -65 ░C to +170 ░C.
The resistor released today is ideal for all types of current sensing, voltage division, and pulse applications in power management for automotive electronic controls such as engine, transmission, anti-lock brakes, audio, and climate controls; inverter controls for down-hole test and measurement equipment and HVAC systems; and VRMs for servers. The device is RoHS-compliant, halogen-free, and Vishay Green.
Samples of the WSLF2512 are available now. Production quantities will be available in November 2016, with a lead time of six to eight weeks for larger orders.
