• Low out-gassing (load element total mass loss < 1.0%, collected volatile condensable materials <0.10%)

Natural Convection
Terminations incorporating heat sinks orientation sensitive due to the direction of air flow over the heat sink.
Flann model number includes a ‘V’ or ‘H’ code to differentiate which is the recommended orientation. It should
be noted that the waveguide broad wall should be vertical in the ‘H’ configuration.

Forced Air
Where stated, the standard natural convection design can be used at 1.5 times its rated power with forced air
cooling; 3 m/s velocity over all heatsink surfaces.

Natural Convection Ratings

• Natural Convection specified power rating @ +20°C ambient – no direct sunlight.
• Ambient power rating adjustment is -/+5% W per +/-10°C
• Vertical design rating is with flange mounted below heatsink – or derate 25%
• Vertical design mounted horizontally derate 35%
• Horizontal design mounted vertically derate 30%
• Horizontal design mounted horizontally but axis through 90° derate 15%
• Natural Convection is increased by 50% if used with Forced Air cooling at 3 m/s.

All terminations have been designed to give high durability and reliability using ceramic elements
encapsulated in aluminium body.
