MALVERN, Pa., Feb. 16, 2016 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE:VSH) today announced a new surface-mount Power Metal Strip® current sense resistor in the compact 1206 case size that combines an extended power rating to 0.5 W with a Kelvin 4-terminal connection that reduces TCR down to 35 ppm and enables tight tolerances down to 0.1 % for increased measurement accuracy. To minimize excess power dissipation, the Vishay Dale WSK1206...18 High Power offers low resistance values down to 0.01 Ω.
Offering twice the power of standard resistors in the 1206 footprint, the device released today allows designers to save board space and reduce costs by utilizing fewer and smaller components. With its 4-terminal construction, the resistor reduces system errors while eliminating the need for system calibration during manufacturing or in the field to further reduce costs and improve end product performance.
The advanced construction of the WSK1206...18 High Power incorporates a solid metal nickel-chrome or manganese-copper resistive element with low TCR (< 20 ppm/°C). This results in a pulse-tolerant, tight-tolerance resistor in the 1206 package size that maintains the superior electrical characteristics of the Power Metal Strip construction.
The WSK1206...18 High Power is ideal for all types of current sensing, voltage division, and pulse applications in power management for cell phones; DC/DC converters for servers, VRMs for laptops, and Li-ion battery safety and management; industrial instrumentation; and automotive electronic control such as engine, transmission, anti-lock brakes, audio, and climate controls.
Like all Power Metal Strip resistors, the device features an all-welded construction that contributes to its superior electrical performance. A proprietary processing technique produces extremely low resistance values ranging from 0.01 Ω to 0.05 Ω, with tight tolerances of 0.1 %, 0.5 %, and 1.0 %. The WSK1206...18 High Power provides low thermal EMF (< 3 μV/°C) and a temperature range from -65 °C to +170 °C. The device is RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the new resistor are available now, with a lead time of six to eight weeks for larger orders.
