Ohmite’s TCH35 TO220 package resistor provides 35W of steady state power when properly used in today’s well defined heat sink applications. These very low induction resistors are built under proprietary processes that deliver more power handling capability than other TO220 package resistors of similar construction. A single screw mounting tab connects to the heat sink and should be accompanied by the use of a thermal compound. The TCH35 Series offers a low thermal resistance to the heat sink of <4.28°C/W. Ohmite offers a wide range of compatible heatsinks for the TCH35 resistor series.
