| 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 <4.28C/W. sPeciFicaTiOns FeaTures * 35W Power Rating @ 25C * Very Low Inductance Design * Single Screw Mounting * Low Thermal Resistance to Heat Sink @ RTH<4.28C/W * Resistance Element is Electrically Insulated from Metal Heat Sink Mounting Tab aPPlicaTiOns * Switching Power Supplies * Snubbers * High Frequency * Voltage Regulation * Low Energy Pulse Loading Electrical Resistance Range: 0.1 to 10K (higher values on request subject to derating) Resistance Tolerance: 5% standard 1% available on request Temperature Coefficient: 0.390-0.410" 0.047-0.055" (9.91-10.41mm) (1.20-1.40mm) Referenced to 25C, R taken at +105C 0.112-0.120" 10 and above: 50 ppmC (2.85-3.05mm) For under 10: 0.230-0.250" 0R6 - 9R9 ....... 100PPM (5.85-6.35mm) 0.571-0.591" 0R4 - 0R59 ..... 150PPM (14.50-15.00mm) 0R2 - 0R39 ..... 250PPM 0R1 - 0R19 ..... 500PPM 0R05 - 0R09 ... 1000PPM 0.046-0.054" 0.157" max. 0.159-0.190" Max.
