Ohmite TL Modular Heat Sinkable Power Resistors
Ohmite TL Modular Heat Sinkable Thick Film Power Resistors are packaged with plastic insulators and quick-connect terminals in a symmetrical aluminum profile for easy heat sink mounting. The TL resistors from Ohmite offer special tapped configurations to reduce onboard component count. The efficient thermal packaging of the TL Series provides improved heat conduction to the heat sink and the resistor's self-insulating package design increases voltage withstanding characteristics when compared to traditional aluminum housings. Other TL Series features include a resistance range 0.3Ω to 4MΩ, a power range of 27W to 275W, and very low inductance. The TL resistors also offer a low profile design and an in-line mounting profile that permits easy adaptation into most heat sink systems.Features
