Ohmite TEH70 Series 70 Watt TO-247 Package Thick Film Power Resistors

HVF resistors are high voltage SMD chip resistors with voltage ratings up to 3,000 V operating.

WFH Series is a low profile, thermally efficient wirewound resistor design. With power ratings from 90-330 watts this resistor is designed to be heat sinked.

Ohmite Manufacturing's family of High Energy Wirewound Resistors employ special winding techniques to maximize the effective joule rating of each resistor. Most wirewound resistors are wound with the objective of meeting the stated power (wattage) rating and keeping cost low through the use of automatic winding equipment. Ohmite High Energy Wirewounds are hand-wound in order to maintain the tightest possible pitch (space between windings) and thereby maximize the mass of the resistive element. Since no wire substitutions are allowed, and no abrasive adjusting is permitted in this family, Ohmite can publish a fixed joule rating and fusing current for each part number in the series.

Ohmite's TBH25 TO220 style resistors are designed for a variety of uses that require intermediate heatsinkable power at an economical price. Engineered for industrial applications, these resistors deliver reliable performance to the traditional high quality Ohmite standard.

Ohmite's TCH35 TO220 package resistor provides 35 watts of steady state power when properly used in today's well defined heat sink applications. These very low inductance resistors are built under proprietary processes that deliver more power handling capability than other TO-220 package resistors of similar size. Standard lead 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.

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 pulse-loading, pre-charge, bleeder, and snubber applications.
