Vishay

Vishay WSLP Very High-Power SMD Current-Sensing Resistor

The small size of the WSLP Series resistors - part of Vishay's Power Metal Strip range - enables them to replace larger current-sensing resistors thus saving on circuit board space.

  • Wide range of package sizes (0603 to 5931)
  • Wide resistance range (0.0003 Ω to 1 Ω) with tight tolerances
  • Excellent overload capability (equivalent to wirewound)
  • Parts are Automotive Grade qualified
  • High power in small case sizes

Product Description

The small size of the WSLP Series resistors - part of Vishay's Power Metal Strip range - enables them to replace larger current-sensing resistors thus saving on the circuit board that in turn will create smaller and lighter products for the consumer.
They are manufactured using proprietary techniques that result in extremely high power and low resistance values with a very small footprint.

WSLP Series resistors feature an all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element. This construction ensures the resistors have very low inductance values an excellent frequency response and low thermal EMF.
The WSLP Series is ideal for all types of current sensing and pulse applications including switching and linear power supplies instruments power amplifiers and shunts.

Typical applications

Automotive: Electronic controls (engine controls climate controls anti-lock brakes etc); Brushless DC motor controls (electronic power steering electric vehicles water pump / oil pump / air conditioning etc Electric and hybrid controls (battery management); Computer: DC/DC converter VRMs for servers Li-Ion battery management / safety; Industrial: Oil and gas well drilling (down-hole test / measurement equipment) Air conditioning / heat pump (inverter control) Brushless DC motor controls; Consumer: Air conditioning / heat pump (inverter control) White goods (inverter control).

Thermal characteristics

High temperature performance (up to 275 °C) low temperature coefficients (down to ± 30 ppm/°C).

Build quality

All-welded construction and solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 ppm/°C).
