Détails du produit
OEP A187A11C Microphone Transformers
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
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
