MHP20S TO-126 Series

Power Resistor

MHP20S Series

IRC’s TO-126 power film resistors satisfy demanding applications for

accurate and stable power resistors housed in the convenient TO-126 case.

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

conductivity and excellent insulation resistance between terminals and tab. The low inductance design makes

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