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.
