14A Series Alumina Body Current Sense F e At u r e S 14AFR Current Sense resistors feature a high tem- perature ceramic body which affords the user higher Ideal for current sensing applications power densities than similar products which utilize 1% Tolerance standard silicone based epoxy molding compounds. The inter- Fixed resistance measuring point nal construction involves a straight, low inductance, 3-piece welded metal element at 1% tolerance. This Low inductance series is stocked in 9 popular resistance values for RoHS compliant easy accessibility.
