TY-302P-B

Overview

The Triad Magnetics TY-302P-B is a through-hole audio transformer designed for data and voice coupling applications. It features a 600-ohm primary impedance and a secondary impedance of 600/600 ohms, providing a 1:1.47 turns ratio. The component operates within a frequency range of 300 Hz to 3.5 kHz and supports up to 4 W of power handling. It offers high isolation with a 1.5 kV rating and utilizes multiple trialloy case interleaves with heavy copper to achieve significant shielding effectiveness.
