MHP TO-220 Series
Power Resistor
MHP Series
• TO-220 housing
• Low inductance (<50nH)
• 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.
