Product details
OEP J30A09C Microphone Transformers
J30A09C microphone transformers from OEP are ideal for impedance matching and signal splitting. These audio transformers are fitted with an electrostatic screen and stray flux copper band. They are encapsulated in a mumetal screening can that ensures low distortion and reduces electrical noise by up to 30 dB. With drive up to +22 dBU these microphone transformers can split input into 3 signals (600 Ω).
4 H nominal inductance at 1 kHz, 0.1 V
675 μH leakage inductance (secondaries) at 1 kHz, 0.1 V
140 pF interwinding capacitance (primary to secondaries) at 20 kHz
