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 IRCs 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. Electrical Data Resistance 1 Power Rating Voltage Thermal Nominal Typ.
