OEP J30A04C Microphone Transformers
J30A04C 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.
1 H single winding primary inductance at 1 kHz, 0.1 V
1.4 mH primary leakage inductance (with windings in series) at 1 kHz, 0.1 V
96 pF interwinding capacitance at 20 kHz with the windings in series
1.4 mH primary leakage inductance (with windings in series) at 1 kHz, 0.1 V
96 pF interwinding capacitance at 20 kHz with the windings in series
Product Application Information
J30A04C audio transformers can be used as microphone step up transformers for matching 150 Ω - 200 Ω to 2.4kΩ - 3.2kΩ.
