OEP A187A14C Microphone Transformers
A187A14C microphone transformers from OEP are ideal for signal splitting and impedance matching. They are encapsulated in a mumetal can and constructed with multiple electrostatic screens. These audio transformers provide dual primary impedance for matching 150 Ω to 15 kΩ.
750 mH primary inductance at 1 kHz, 0.1v
44 pF interwinding capacitance at 20 kHz (primary 1 to screens)
64 pF interwinding capacitance at 20 kHz (primary 2 to screens)
109 pF interwinding capacitance at 20khz (secondary to screens)
12 pF interwinding capacitance at 20 kHz (primaries to secondary when primaries are in series)
Note
Do not pass DC through windings
