R2 Series

For TO-220, TO-247, and TO-264

F E AT U R E S

Ohmite’s R2 Series (patent pending) heatsink pro-

vides a large surface area along with our C Series

clipping mechanism to attach to a TO-220, TO-247,

or TO-264 package. The self-aligning features of the

clip assure secure attachment and enhanced thermal

performance. Because no screws are required for

device mounting, additional fins can be added to the

rear side of the heatsink for increased total surface

area in a more compact space.

• Reduced

Assembly Cost:

C Series camming clips

make fasteners and fixtures obsolete, along with

stray metal filings from tapped holes.

• Maximum

Repeatability:

clamping force of the clip

is not degraded by repeated loading and unloading.

• Maximum

Heat Transfer per Unit Space:

maximum

surface area per unit volume and consistent mount-

ing force reduces thermal resistance

• Maximum

Resistance to Shock and Vibration:

light

weight, resilient clips lock the component in place

and are highly resistant to shock and vibration

• Maximum

Reliability:

helps prevent short circuits

by eliminating metal particles from thread tapping

• RoHS

compliant
