CHF190104KxBF Series 1 kW Stripline Termination

Typical Performance

Mounting High Power Devices

The mounting surface must be flat to less than 0.0254 mm (0.001 inch) and devoid of

scratches or burrs. The underside of the flange should be brushed with thermal

grease prior to being fastened to the heat sink with mounting screws. The thermal

grease will fill any air gaps and help to keep a good thermal contact.

Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place.

Ensure that the temperature on the surface of the flange does not exceed 110 ˚C when

running at 100 % of load. If the temperature increases then derate the power.
