Reliability Considerations

The above procedure yields the upper limit for the power dissipation for continuous wave

(cw) and pulse applications which corresponds to the maximum allowed channel

temperature. For best reliability keep the channel temperature low. The following formula

allows to track the individual contributions which determine the channel temperature.

TCh =

Channel
