TDH Series Ohmite’s TDH resistor is an economical solution to intermediate power application design requirements. TDH’s reliable thick film on alumina substrate construction can be easily heat sinked for higher power performance. TDH resistors are ideal for pulseloading, pre-charge, bleeder, and snubber applications. 10.1mm 45° 0.5mm F e at u r e s 4.5mm 7.87mm 1.1mm ±0.5 0.5mm Land Pattern 8.6mm 1.4mm 1.5mm ±0.5 4.8mm 0.9mm 0.5mm 8.51mm 2.63mm 1.5mm ±0.5 3.81mm 1.65mm 2.54mm 5.08mm DPAK style power package for surface Soldering note: During surface mount soldering the mounting applications; 35W power soldering temperature profile must not cause the rating at 25°C case temperature. metal tab of this device to exceed 220°C (260°C for the TDH35H)! • 35 Watt power rating at 25°C • SMD - DPAK package configuration • Heat resistance to cooling plate: Rth <4.28°C/W • A molded case for environmental protection. • Resistor element is electrically insulated from the metal sink tab.
