890SD Resistor Selection 
These small, metal-clad resistors should be mounted on a 
heatsink (back panel) and covered to prevent injury from 
burning. 
There are four resistor values available. 
Each one can support "10 x Power Rating" for 5 seconds. 
Refer to the following "Calculation". 
IMPORTANT  The continuous rating quoted is not to be exceeded 
under repetitive loading.
