Electrical Data

IRC’s MHP series resistors satisfy demanding applications for accurate

and stable power resistors housed in the convenient TO-247 case. The

resistance element is isolated from the mounting tab by an alumina ceramic layer, providing very low thermal

resistance and ensuring high insulation resistance between terminals and metal back plate. The non-inductive

design makes these products especially useful in high frequency and high speed pulse applications.
