Power Resistor Heat Sinks

Dec 14, 2011 11:26 AM


Designed for applications requiring high power densities and where forced air cooling is present, Ohmite has released a larger version of their MV/MA heatsink which provides even more heat dissipation. The longer, more efficient fin extrusions on the new version give nearly twice the thermal performance as their smaller MV/MA 102 product.
The MV/MA 302 heatsink is 2.2 inches across by 1.71 inches tall and uses the same installation mechanism which provides two internal spring clips for mounting up to four TO-247 or TO-264 devices. The convenient spring clips eliminate the need for mounting holes and screws, are resilient and provide the same amount of force after repeated use.

The MV/MA 302 heatsink can be supplied in custom lengths and customers can specify the number of spring clips they want. Designed originally for the Ohmite TEH70, TEH100 and TFH85 resistors customers using any active devices in TO-247 or TO-264 packages will benefit from this heatsink.
