OX/OY Series

F ꢀ at u ꢁ ꢀ S  
The OX/OY Series of fixed  
ceramic resistors are ideal for  
circuitry associated with surges,  
high peak power or high energy.  
They offer enhanced perfor-  
mance in high voltage power  
supplies, R-C snubber circuits,  
and inrush limiters. The OX/  
OY resistors can often replace  
carbon composition resistors  
which can be difficult to source.
