Ohmite 100W TO-247 Thick Film Power Resistor

Ohmite TEH100 Series 100W TO-247 Thick Film Power Resistors offer low ohmic value and non-inductive design for high frequency and pulse loading applications, especially power supplies. 100W power rated at 25ºC case temperature, the TEH100 series features non-inductive performance and low thermal resistance. The resistors were designed for non-induction, RoHS compliance, and the resistor package is totally insulated from the heat sink. The Ohmite TEH100 Series 100W TO-247 Thick Film Power Resistors have a molded housing for environmental protection and single screw mounting simplifies attachment to the heat sink.

W Heatsinks for TO-247

The unique design (patent pending) of the Ohmite W Series heat sinks combines a tin-plated, solderable, integral spring clip with an extruded aluminum heat sink body for an all-in-one solution to the through-hole mounting of TO-220 or TO-247 packages. These self-aligning heat sinks feature solderable feet and an integrated clip with 13.2 (lbf) of force on the center of the device to enhance thermal performance.
