P Series Heatsinks Forged Pin Fin heatsink for TO-220, TO-247 and TO-264 devices Ohmite introduces the P series forged pin-fin heatsink (Pat. Pending). The P series heat sinks offer an all- in-one solution combining a compact design with a universal cam clip system for TO-220, TO-247, TO-264 package devices. This powerful forged pin heatsink is designed to be thru-hole soldered to the PCB board. The forged pin design allows forced convection cooling in multiple directions. The pin fin design allows for a larger surface area creating minimum thermal flow impedance. The P series is the ideal type of heat sink for high power and small size (1U or 2U) electronic packaging with natural and forced convection cooling.
