14A Series
Alumina Body Current Sense
F e At u r e S
• Ideal for current sensing applications
• 1% Tolerance standard
• Fixed resistance measuring point
• Low inductance
• RoHS compliant
14AFR Current Sense resistors 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 inter-
nal 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.
