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.

**The epoxy that is used to cast these parts has a workable temperature range of –40°C to +105°C
Under a normal rate of change, this does not include thermal shock.
Variations in the transformer materials and environmental conditions may reduce the workable temperature range.
