LXP18 series power resistors

Detailed Product Description

LXP18 series power resistors

EBG offers the totally encapsulated and insulated TO-220 package for low ohmic value and non-inductive design for high frequency and pulsing applications.Ideal use is for power supplies. This series is rated at 18 Watts mounted to a heat sink.
The special features include:18 Watt power rating at 25°C case temperature
TO-220 package configuration,Single screw mounting simplifies attachment to the heat sink.
A totally molded housing for enviromental protection.Non-Inductive design,Resistor package totally insulated from heat sink.
