IRCTT TFP-MHP140LF-1K00-J

MHP TO-247 Series
Power Resistor
MHP TO-247 Series
• TO-247 housing
• Low inductance (<50nH)
• 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.

Application Notes:
250
1. Insulating material is unnecessary between the heat sink
and the tab, as the resistor film is isolated by the internal
alumina substrate.
200
2. When mounting with a fastener, thermal grease is
recommended.
150
3. Thermal design should satisfy the following equation: Case
Temperature (Tc) + [Thermal Resistance (ROJC) x Power
applied (Watts)] ≤ 155°C over the full operating temperature
of the application.
