JTI – HEAT SINKS FOR POWER LEDs
882 SERIES – RADIAL FIN HEAT SINK FOR “STAR” LED PACKAGES
Wakefield's new 882 series heat sinks can be used with LEDs in the
star package from Lumileds, Osram, and others. The radial design
and fin area is ideally suited for natural convection applications such
as ceiling lighting. A fan can also be used for increased performance
in a forced convection application. Three sets of mounting holes allow
maximum flexibility.

The six .090 holes accommodate the LED module with # 4-40
screws,
The six .153 holes can accommodate a multi-LED circuit
board, mount to a panel with # 10-32 screws, or act as a
conduit for wires
The four .201 holes can be used to mount the heat sink to a panel
with # 1/4-20 screws
