Through Hole Audio Transformer 1 + 1kΩ

Do not pass DC through the windings. OEP A187A10C Audio Input Transformers. A187A10C audio input transformers from OEP have multiple electrostatic and magnetic shields and provide galvanic isolation. The A187A10C transformer is a high ratio step down transformer featuring Faraday shielding that reduces hum and stray magnetic interference. +21.5dbu maximum input level at 20 Hz with >1% distortion 250 Vrms proof voltage from winding to winding and screens to winding 155 mH primary leakage inductance at 1 kHz 42 pF interwinding capacitance at 1 kHz for primary to secondary 1 63 pF interwinding capacitance at 1 kHz for primary to secondary 2 39 pF interwinding capacitance at 1 kHz for primary to shield. Product Application Information. These audio input transformers are suitable for long cable runs without HF loss. They can be used for coupling instrument pickups to low impedance microphone inputs and unbalanced line level to balanced microphone outputs.
