TY-305P

Overview

The TY-305P is a through-hole audio transformer from Triad Magnetics designed for data and voice coupling applications. It features a 600 Ohm primary to 600 Ohm secondary impedance ratio with a single channel configuration. The unit supports an operating temperature range of -20°C to +85°C and provides up to 95dB shielding via multiple trialloy case interleaves and heavy copper shading rings. Key electrical specifications include a typical return loss of 10dB, a power level range of -45dB to 7dB, and a maximum DC current rating of 75 mA.

Feature Summary

• Provides high-level electromagnetic interference protection through specialized shielding construction.
• Facilitates signal isolation and impedance matching between balanced lines.
• Supports longitudinal balance requirements for telecommunications circuits.

Applications

• Data and voice coupling in communication systems
