The MET-31-T is a high-reliability, miniature encapsulated audio coupling transformer. It is designed to operate at a power level of 50 mW with matching primary and secondary center-tapped impedances of 600Ω. Key electrical characteristics include a 1.0:1.0 turns ratio, a frequency response of ±2.0 dB from 300 Hz to 100 kHz, and a maximum DC unbalance of 3.0 mA in the primary. The durable epoxy-molded construction with plug-in terminals ensures precision and reliability in demanding audio circuit designs.
