A187A11C microphone transformers from OEP are ideal for signal splitting and impedance matching. These audio transformers provide two isolated balance outputs when loaded with 1 kΩ. Constructed with multiple electrostatic screens, these dual output microphone transformers have excellent common mode rejection. They are encapsulated in a mumetal screening can.
Proof voltage of 250 Vrms from windings to screen and from primary to secondaries 2.85 H nominal inductance at 1 kHz, 0.1 V Interwinding capacitance of 180 pF at 1 kHz for primary to screens Interwinding capacitance of 71 pF for secondary 1 to screens Interwinding capacitance of 113 pF for secondary 2 to screens
Note
Do not pass DC through the windings
