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: 2.0W @ 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 50 Khz. +/- 1.5db

-Freq. range @ +27 dbm is 300 Hz. to 50 Khz. +/- 1.5db

-Freq. measurements with no D.C. saturation.
