The TY-301P is a data/voice coupling audio transformer used for impedance matching, isolation, and line balancing. It features a primary impedance of 600 Ohms and a secondary impedance of 900 Ohms, with a typical insertion loss of 1.0 dB. The transformer operates over a power level range of -45 dBm to +7 dBm and maintains a frequency response of ±0.5 dB from 300 to 3500 Hz. Designed to meet FCC Part 68, it offers a dielectric strength of 1500VAC. These characteristics make it suitable for applications such as repeat coils, bridging, and hybrid circuits.
