Notes:
(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 3.3°C/W and a maximum resistor temperature of 155°C.
(4) Surface mount package also available, please call factory.
(5) Current rating: 25A maximum.

TO-220 housing
Low inductance and capacitance for
high frequency circuits
Available in 20W, 35W, or 50W
High stability film resistance elements
RoHS compliant
Approved to DSCC drawings 07017 and 07018
IRC’s MHP series resistors satisfy demanding applications for accurate
and stable power resistors housed in the convenient TO-220 case. The
resistance element is isolated from the mounting tab by an alumina ceramic layer, providing very low ther-
mal resistance and ensuring high insulation resistance between terminals and tab. The non-inductive design
makes these products especially useful in high frequency and high speed pulse applications.
