Ohmite TCH35 Thick Film 35W Power Resistors
Ohmite TCH35 Thick Film 35W Power Resistors are TO220 packaged devices that provide 35W of steady-state power when properly used in heat sink applications. The TCH35 resistors from Ohmite have very low inductance and are built under proprietary processes that deliver more power handling capability than any other TO220 package resistors of similar size. This series offers a resistance range from 0.1Ω to 10KΩ, a 5% resistance tolerance as standard, a single-screw heat sink mounting, and a resistance element electrically insulated from the metal heat sink mounting tab.
