OEP J30A14C Microphone Transformers J30A14C microphone transformers from OEP are ideal for signal splitting and impedance matching. These audio transformers are fitted with an electrostatic screen and stray flux copper band. They are encapsulated in a mumetal screening can that reduces electrical noise by up to 30 dB and ensures low distortion. These audio transformers provide galvanic isolation. Maximum input signal of +18 dBU
1 H nominal primary inductance at 1 kHz, 0.1 V
150 pF interwinding capacitance at 20 kHz, 0.1 V (primaries to screen)
45 pF interwinding capacitance at 20 kHz, 0.1 V (secondaries to screen)
75 pF interwinding capacitance at 20 kHz, 0.1 V (primaries to secondaries)
