OEP PCB Audio Transformer 11kΩ

OEP A187A15C Microphone Transformers

A187A15C microphone transformers from OEP are ideal for impedance matching and signal splitting. They are encapsulated in a shielding mumetal can and constructed with multiple electrostatic screens. These audio transformers match 150 Ω to 150kΩ. A187A15C audio transformers are suitable for use with high impedance FET and tube amplifiers.
