TFP-SMHP35LF-0R05-J Datasheet, PDF (1/3 Pages) IRC - a TT electronics Company. – SMHP35 Series Power Resistor

SMHP35 Series
Power Resistor
SMHP35 Series
• 270°C reflow compatible
• TO-263 housing
• Low inductance and capacitance for high frequency circuits
• 35W power rating
• High stability film resistance elements
• RoHS compliant
IRC’s SMHP series resistors satisfy demanding applications for accurate
and stable power resistors housed in the convenient TO-263 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.
