Vishay Introduces Automotive Grade Power Metal Strip Resistor WSHP2818

Thursday, August 23, 2018

Vishay introduces a new automotive grade Power Metal Strip® resistor, the WSHP2818, with a power rating of 10W and a 2818 form factor. The Vishay Dale WSHP2818 has a high power equivalent to a larger resistance in a smaller footprint, saves space in automotive, industrial, consumer, and computer products, reduces component count, and replaces lead resistance with surface mount Greatly speed up assembly.

The device released today features a unique structure that improves the thermal management design, allowing the 10W resistor to maintain the excellent electrical characteristics of the Power Metal Strip structure in the 2818 package size. This high power density resistor is AEC-Q200 qualified and can be used to replace larger high power components or multiple smaller power devices, which reduces the required board space and allows for smaller, lighter designs. Final product.

The WSHP2818 has a resistance from 1mΩ to 100mΩ with tolerances as low as ±0.5%. The all-welded construction is ideal for automotive engine control and anti-lock braking systems, brushless DC motor control, battery management for electric and hybrid vehicles, various types of galvanic, partial pressure and pulse applications, downhole testing and measurement Inverter control of equipment, air conditioning and heat pump, and VRM for DC/DC converters and servers.

The resistors are low-TCR (±20ppm/°C) solid metal nickel-chromium or manganese-copper alloy resistor cores with inductance values ​​less than 5nH, thermal EMFs less than 3μV/°C, and operating temperatures ranging from -65°C to +170°C. The device is RoHS and Vishay green and halogen free.
