WSLP1206 Very High-Power 1 W Surface-Mount Power Metal Strip® Resistor

One of industry's first surface-mount power metal strip resistors in 1206 package

Vishay/Dale's WSLP1206 Very High-Power 1-W Surface-Mount Power Metal Strip® Resistor Vishay's WSLP1206, a surface-mount Power Metal Strip resistor, is one of the industry's first 1 W current sensing resistors in the very small 1206 package size. The WSLP1206 resistor features a very low 1 mΩ to 50 mΩ resistance value range and high-temperature performance up to 170/°C.

The small size of the WSLP1206 resistor allows it to replace larger current sensing resistors, saving space on the circuit board that in turn will create smaller and lighter products for the consumer. It is intended for current sensing and pulse applications in DC-to-DC converters for computers, VRMs for laptops, and Li-Ion battery safety and management, as well as electronic automotive systems, including engine controls, multi-media electronics, climate controls, and anti-lock brakes.

Manufactured using proprietary techniques that result in extremely high power and low resistance values, the WSLP1206 features all-welded construction with a solid metal nickel-chrome or manganese-copper alloy resistive element. The resistor offers very low inductance values from 0.5 nH to 5 nH, an excellent frequency response to 50 MHz, and low thermal EMF of less than 3 µV/°C.

Features
  • Very high power to foot print size ratio (1 W in 1206 package)
  • Ideal for all types of current sensing and pulse applications including switching and linear power supplies, instruments, power amplifiers, and shunts
  • Proprietary processing technique produces extremely low resistance values (down to 0.001 Ω)
  • All welded construction
  • Solid metal Nickel-Chrome or Manganese-Copper alloy resistive element with low TCR (<20 ppm/°C)
  • Very low inductance 0.5 nH to 5 nH
  • Excellent frequency response to 50 MHz
  • Low thermal EMF (<3 µV/°C)
Applications
  • Li-Ion battery management
  • DC/DC converters in switching power supplies
  • VRMs in notebooks PCs
  • Disc drive motor controls
  • Automotive controls for body and powertrain
