MINIATURE EPOXY POTTED AUDIO TRANSFORMER
6
Audio input, line matching and output transformers
Epoxy potted in an attractive molded case, Pin type, P.C. board
mount, (min. 0.187” length)
Rugged epoxy potted construction produces a completely
sealed unit withstanding severe environmental conditions.
1
In some models where no center tap is present (on the secondary), pin 5 is omitted.
Secondary may be used as primary and primary as secondary.
Will withstand soldering for 10 sec. @ 260 degrees C, ambient temp. 85 degrees C max.
