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:
1.
Insulating material is unnecessary between the heat sink
and the tab, as the resistor film is isolated by the internal
alumina substrate.
2. When mounting with a fastener, thermal grease is
recommended.
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.
4. Resistor film temperature is not to exceed 155°C during
operation.
5. This product is RoHS compliant by exemption according to
RoHS directive 2002/95/EC exemptions 5 & 7, as they apply
to lead in glass and internal solder connections.
