Through Hole Audio Transformer 1 kΩ, 4 kΩ 100mW

This range of 100 mW 300 Hz audio transformers from OEP feature electrostatic screening and are suitable for PCB mounting. They are ideal for use in low-power outputs and can be used for both microphone inputs and line inputs.

A mumetal screening can is available for these audio transformers. See 210-6469

Do not pass DC through the windings.
