OEP A187A15C Microphone Transformers


A187A15C microphone transformers from OEP are ideal for impedance matching and signal splitting. They are encapsulated in a shielding mumetal can and constructed with multiple electrostatic screens. These audio transformers match 150 Ω to 150kΩ. A187A15C audio transformers are suitable for use with high impedance FET and tube amplifiers.

5.3 H primary inductance at 100 Hz, 0.1 v
280 μH typical primary leakage voltage at 1 khz, 0.1 v
130 pF interwinding capacitance at 10 kHz, 0.1V (winding to winding)
254 pF interwinding capacitance at 10 kHz, 0.1V (primary to screen)
