Vishay Intertechnology has unveiled a new Automotive Grade Power Metal Strip resistor that delivers a high 10 W power rating in the compact 2818 case size, allowing it to save space and reduce component counts in automotive, industrial, consumer, and computer applications, while offering a surface-mount alternative to leaded resistors.
The WSHP2818’s all-welded construction is ideal for all types of current sensing, voltage division, and pulse applications in automotive engine controls and anti-lock braking systems, brushless DC motor controls, and battery management for electric and hybrid vehicles; down-hole test and measurement equipment; inverter controls for air conditioners and heat pumps; and DC/DC converters and VRMs for servers.
The AEC-Q200 qualified resistor features an improved thermal management design. Its high power density allows it to replace larger high power components or multiple lower power devices, reducing board space requirements and enabling the design of smaller and lighter end products.
The resistor features extremely low resistance values from 1 mΩ to 100 mΩ, with tolerances down to ± 0.5 %.
The device has a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (± 20 ppm/°C), low inductance values of < 5 nH, low thermal EMF down to < 3 µV/°C, and an operating temperature range of -65 °C to +170 °C. The device is RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the WSHP2818 are available now, with a lead time of six to eight weeks for larger orders.
