Note:
1. Electrically isolated metal tab.
2. Recommend the use of thermal grease between metal tab and heat sink.
3. Thermal design should account for a thermal resistance between resistor and tab of 0.9°C/W and a maximum resistor temperature of 155°C.
4. Resistances greater than 220 are available, please call factory.
5. Current rating: 25A maximum.

TO-247 housing
Low inductance and capacitance for
high frequency circuits
Available in 100W or 140W
High stability film resistance elements
RoHS compliant terminations
Insulated metal back plate
Approved to DSCC drawing 07019
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.
