## **VM Series Variable Mount Heatsink Series** Ohmite introduces this new versatile heatsink design. This new design can accommodate several different industry packages. This design also lets the customer choose a mounting style using screws or clips for secure mounting to the heatsink. These one of a kind heatsinks are offered in a vertical (free convection cooling) or horizontal format (forced convection cooling) to fit customer applications. **==> picture [165 x 25] intentionally omitted <==** **----- Start of picture text -----**<br> Horizonral<br>Vertical<br>Mounting Style<br>Mounting Style<br>**----- End of picture text -----**<br> ## ~~**S e r i e S S P e c i F i c at i O N S**~~ **Heatsink Surface Area Weight Length L or Surface Part Number Mount (in[2] / mm[2] ) (oz / g) Height H (mm) Finish** VM1-038-1AE vertical VM2-038-1AE horizontal 39.6 / 25,546 1.48 / 42 38.6 anodized VM3-038-1AE* universal *Discontinued ## ~~**c h a r a c t e r i S t i c S**~~ **Heat Sink** Aluminum Alloy 6063-T5 or Equivalent with either degreased or black anodized finish **Solder Foot** Cold-rolled Steel, Per ASTM A-366 with pure tin over copper strike.
