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 size. Standard terminal forms are provided for manual or automatic insertion. 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.

THIS PRODUCT IS DESIGNED FOR USE WITH PROPER HEATSINKING.
Maximum base plate temperature of the resistor must be monitored and kept within specified limits to establish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor.
