14AFR Current Sense resis-
tors feature a high tem-
perature 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 induc-
tance, 3-piece welded metal
element at 1% tolerance. This
series is stocked in 9 popular
resistance values for easy
accessibility.
