Vishay Automotive Grade WFM Current Sense Resistors

Vishay Intertechnology introduces new Automotive Grade WFM Power Metal Plate™ current sense resistors featuring 2 W and 3 W power ratings in 2010- and 2512-sized packages. 

  • Allow designers to use a single high power resistor instead of running multiple resistors in parallel, which can cause current measurement errors
  • Improved power density promotes space savings on the circuit board that will in turn enable smaller and lighter products for the end consumer
  • Feature a construction that incorporates an improved thermal management design utilizing a copper heat spreader, enabling high power density and lifetime stability
  • A proprietary processing technique enables a wide range of low resistance values 
  • Feature a solid metal manganese-copper and nickel-chromium alloy resistive element with low TCR (< 20 ppm/°C) 

 

Features

  • High 2 W and 3 W power ratings
  • Available in 2010 and 2512 package sizes
  •  Resistance values from 5 mO to 500 mO, with tolerances down to ± 1.0 %
  • ow inductance values of 0.5 nH to 5 nH
  • Low thermal EMF down to < 3 µV/°C
  • Operating temperature range of -65 °C to +170 °C
  • Excellent frequency response to 50 MHz
  • RoHS-compliant, halogen-free, and Vishay Green

 

Applications

  • Automotive electronic controls, brushless DC motor controls, and battery management for electric and hybrid vehicles
  • High power inverter / converter controls and large motor drives for industrial applications
  • Power supplies for downhole instrumentation
  • Inverter control for consumer appliances and HVAC systems
  • Power management, conversion, and safety in servers and other computing applications
