## **Attachable heatsink** 

– narrow version with better thermal resistance – max. 14.5 mm wide – 3 different lengths for varied dissipation power 

- takes less space than any other attachable heatsink 

– simple assembly by pushing the heatsink onto the TO 220 housing 

– the cooling fingers form spring clamps **(1+2)** , which pushes the TO 220 and it's mounting flange onto the heatsink **(3)** – optimum heat transfer due the constant pressure on the entire contact surface of the TO 220 cases 

– effective heat emmision with horizontal and vertical mounting 

without soldering lug
