(2) termination has two terminals, one is plate tab terminal and other is backing plate that is to be solder mounted on to heat sink. rftl series ? high power surface mount termination for dc up to 3ghz applications ? small size and wide frequency range ? long life and temperature stability resulting from thin ?lm technology sheet 1 of 2
