M3G-SERIES

(28V Input, Single/Dual Output)

Ensure that flatness of the plate where M3G converter to be mounted is no greater than 0.003” per linear inch.

It is recommended that a thermally conductive gasket is used to promote the thermal transfer and to fill any

voids existing between the two surfaces. IR recommends Sil-Pad 2000 with the thickness of 0.010". The

shape of the gasket should match the footprint of the converter including the mounting flanges. The gasket

is available from IR. The M3G-series converter requires either M3 or 4-40 size screws for attachment

purposes.

The procedure for mounting the converter is as follows:

1.

Check the mounting surfaces and remove foreign material, burrs if any or anything that may

interfere with the attachment of the converter.

2.

Place the gasket on the surface reserved for the converter and line it up with the mounting holes.

3.

Place the converter on the gasket and line both up with mounting holes.

4.

Install screws using appropriate washers and tighten by hand (~ 4 in·oz) in the sequence shown below.

Application Notes:

A) Attachment of the Converter.

5. Tighten the screws with an appropriate torque driver. Torque the screws up to 6 in·lb in the sequence

shown above.

The following procedure is recommended for mounting the converter for optimum cooling and to circumvent

any potential damage to the converter.
