Vishay Dale WSLF2512 Surface-Mount Device Combines High Power Density with Low Resistance and TCR
June 14, 2017 - New Yorker Electronics will be distributing the new Vishay Dale WSLF2512 Surface-Mount Power Metal Strip® Current Sense Resistor that combines a high power rating up to 6W, TCR down to ±70 ppm/°C, and extremely low resistance values down to 0.0003Ω in the 2512 case size.
Providing a power density of 192W/in^2, the WSLF2512 is a 2017 Vishay Super 12 Featured Product. It 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 (-65°C to +170°C), 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 0.0003Ω to 0.003Ω, with tolerances of ±1.0% and ±5.0%. The device provides low thermal EMF (<3µV/°C) and a very low inductance (<2nH).
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.
New Yorker Electronics is a franchise distributor for Vishay Dale and carries the full line of 2017 Vishay Super 12 Featured Products as well as its complete line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
