A187A16C/1 microphone transformers from OEP have been designed for matching low output moving coil pickups to balanced valve pre-amplifiers. These audio transformers are ideal for impedance matching and signal splitting. A low distortion core enables low harmonic distortion while multi-layered winding enables improved coupling and reduces leakage inductance.
500uV maximum input voltage 640 mH nominal primary inductance tolerance at 1 kHz, 0.1 V 430 μH typical primary leakage inductance at 1 kHz, 0.1 V 35 pF interwinding capacitance at 20 kHz, 0.1 V (screens earthed) 10 Hz to 30 kHz ±0.5dB frequency response
