Description
The MH005-Series Power Modules are dc-dc converters that operate over an input voltage range of 4.5 Vdc to
14 Vdc and provide precisely regulated dc outputs. The outputs are isolated from the inputs, allowing versatile
polarity configurations and grounding connections. The modules have maximum power ratings of 5 W with a
typical full-load efficiency of 73%.
The modules are PC board mountable and encapsulated in nonconductive cases. The modules are rated to full
load at 100 °C case temperature with no external filtering or heat sinking.

Thermal Considerations
The MH005-Series Power Modules are designed to operate in a variety of thermal environments. As with any
electronic component, sufficient cooling must be provided to help ensure reliable operation. Heat-dissipating com-
ponents inside the module are thermally coupled to the case to enable heat removal by conduction, convection,
and radiation to the surrounding environment.
The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figures 19
and 20 was used to collect data for Figures 21 and 22.
The graphs in Figures 21 and 22 provide general guidelines for use. Actual performance can vary depending on
the particular application environment. The maximum case temperature of 100 °C must not be exceeded.
