MHP TO-247 Series Power Resistor MHP TO-247 Series * 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.
