CR Series
Heatsink with universal cam-clip
Ohmite introduces the CR-series, configurable and
patented (Pat. Pending) high performance, heatsinks
with universal cam-clip for TO-247, TO-264, and
other packages. This proprietary heat sink provides
tool and fixture free assembly operation with its Pat
Pending cam clip system. The CR series heatsinks
are comparable to some AAVID popular MAX-clip
heat sinks in footprint and thermal performance. It is
the ideal type of heat sink for high power density and
small size electronic packaging with forced convec
tion cooling.
F E AT U R E S
• Minimum assembly cost and labor: Spring Clips
make the mounting holes, fasteners, tools and fix-
tures obsolete in assembly operations & reduce
costs.
• Maximum Repeatability: Constant spring force
over repeated assembly/disassembly
• Maximum Reliability: Resilient spring action locks
electronic component in place. Fewer parts in
assembly and no fasteners and washers required.
Prevent short circuit by eliminating metal particles
generated from hardware or thread tapping
Design Flexibility: Maximum flexibility for dynamic
device locations and power up grading. “Configure-
to-Fit” gives designers total freedom to configure
heat sink needed to fit their dynamic design envi-
ronments.
