TL Series

Modular Heat Sinkable

Thick Film Power

The TL Series add heat sinkable options to the

thick film resistor family. The resistor element

is packaged with plastic insulators, and quick-

connect terminals in a symmetrical aluminum

profile for easy heat sink mounting. Special

tapped configurations are offered to reduce on

board component count.

Efficient thermal packaging provides improved

heat conduction to the heat sink. Self-insulating

package design increases voltage withstanding

characteristics when compared to traditional

aluminum housings. The in line mounting profile

makes the TL Series easily adaptable to most

heat sink systems. Thermal compound is always

recommended when heat sinking.

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.
