OEP A187A12C Audio Input Transformers
A187A12C audio input transformers from OEP provide galvanic isolation and are constructed with multiple electrostatic and magnetic shields. They feature a low distortion core and reduce the audio hum and buzz between the ground at the send and receive terminations of the signal.
Proof voltage of 250 Vrms from windings to screen and from primary to secondary
140 pF interwinding capacitance at 20 Hz (primary to screens and secondary to screens)
1.2 mH primary leakage inductance at 1 kHz
2.82 H nominal inductance for each winding
Product Application Information
Suitable applications include ground loop elimination, high common mode rejection and dual electrostatic shields. Another use for these audio transformers is unbalanced line level to balanced microphone outputs.
Note
Do not pass DC through the windings.
