TL54FR500E Datasheet, PDF (1/2 Pages) Ohmite Mfg. Co. – Modular Heat Sinkable Thick Film Power

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.
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.
FEATURES
• Very low inductance
• Low profile design
• In-Line Mounting Profile
• ¹/4” Quick connect terminals
• Consult factory for common,
isolated, or special multiple tap
options.
APPLICATIONS
• Semiconductor Balancing
• Frequency Converters
• Snubber
• In-Rush Current Limiter
• Bleeder Resistor
• Power Switching
• Voltage Dividers
