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. 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. F E A T U R E S
