Audio Transformer

The Audio Type Transformers EID-107, EID-108 and EID-109 series. Miniature epoxy potted P.C. Board mount audio transformer.

107 Series (150 mw)

108 Series (500 mw)

109 Series (2 watt)

Key Features:

Audio input, line matching and output transformers.
Epoxy potted in an attractive molded case, Pin type P.C. board mount (min. 0.187" length).
In some models where no center tap is required (on secondary), pin No. 5 is omitted.
Power level ratings are maximum at lowest frequency rating (noted by series above charts) power can be increased slightly at higher frequencies (except EID-107X).
Will withstand soldering for EID-10 sec. @ 260 degrees C, ambient temp. 85 degrees C max.
