· 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.
