14A Series

14A Series
Alumina Body Current Sense
F e at u r e s
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.  
•Ideal for current sensing applications
•1% Tolerance standard
•Fixed resistance measuring point
•Low inductance
•RoHS compliant
