OEP J30A03C Microphone Transformers
J30A03C 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. J30A03C audio transformers offer galvanic isolation and three section winding allows for improved decoupling.
Features
The windings can be connected in parallel for 150 Ω matching in series for 600 Ω
Common mode rejection ratio >60 dB at 10 kHz
658 μH minimum inductance when primaries are in series at 1 kHz, 0.1 V
800 mH minimum inductance per winding at 1 kHz, 0.1 V
186 pF interwinding capacitance (windings in series) at 10 kHz
Product Application Information
Suitable applications include DAC outputs, phono inputs and ground loop isolation. These audio transformers are ideal for use with microphone or line inputs with an increased input signal of +6 dBV.
