The TL Series add heat sink-  
able options to the thick film  
resistor family. The resistor  
element is packaged with plas-  
tic insulators, and quick-con-  
nect terminals in a symmetrical  
aluminum profile for easy heat  
sink mounting. Special tapped  
configurations are offered to  
reduce on board component  
count.

Material  
Efficient thermal packag-  
ing provides improved heat  
conduction to the heat sink.  
Self-insulating package design  
increases voltage withstanding  
characteristics when compared  
to traditional aluminum hous-  
ings. The in line mounting pro-  
file makes the TL Series easily  
adaptable to most heat sink  
systems. Thermal compound  
is always recommended when  
heat sinking.

THIS PRODUCT IS DESIGNED FOR  
USE WITH PROPER HEATSINKING.  
Maximum base plate temperature of the resistor must be  
monitored and kept within specified limits to establish the  
power rating. Best technique is to attach a thermocouple  
to the side of the base plate of the resistor. Temperature of  
plastic housing or heat sink cannot be used to establish rating  
of the resistor.
