Alumina Body Current Sense 

Res 14a product image

 

Features

  • Ideal for current sensing applications
  • 1% Tolerance standard
  • Fixed resistance measuring point
  • Low inductance
  • RoHS compliant

 

14AFR Current Sense resistors feature a high temperature ceramic body which affords the user higher power densities than similar products which utilize silicone based epoxy molding compounds. The internal construction involves a straight, low inductance, 3-piece welded metal element at 1% tolerance. This series is stocked in 9 popular resistance values for easy accessibility.
