OX/OY Series
Ceramic Composition 
10% Tolerance 
FeatureS
The OX/OY Series of fixed 
ceramic resistors are ideal for 
	Replaces	 1	 and	 2	 watt	
circuitry associated with surges, 
carbon composition 
high peak power or high energy. 
resistors
They offer enhanced perfor-
	Meets	 high	 energy	
mance in high voltage power 
density demands
supplies, R-C snubber circuits, 
	High	 peak	 power	
and inrush limiters. The OX/
OY resistors can often replace 
	10%	 Tolerance
carbon composition  resistors 
which can be difficult to source.
