108N
MINIATURE EPOXY POTTED AUDIO TRANSFORMER
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.
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.
Power level: 500mw @ 300 Hz. to 50 Khz.
-Freq. range @ +0 dbm is 300 Hz. to 50 Khz. +/- 1.5db
-Freq. range @ +10 dbm is 300 Hz. to 100 Khz. +/- 1.5db
-Freq. range @ +20 dbm is 300 Hz. to 100 Khz. +/- 1.5db
-Freq. measurements with no D.C. saturation.
