TY-300P

Overview

The TY-300P is an audio transformer from the Triad Magnetics TY series, designed for data and voice coupling applications. It features a 1:2 turns ratio with 600 Ohm primary and secondary impedances. The component supports a frequency range of 300 Hz to 3500 Hz and provides isolation up to 1500 VAC. Constructed with pin terminals for through-hole mounting, it utilizes multiple trialloy cases interleaved with heavy copper shading rings to achieve significant shielding effectiveness.

Feature Summary

• Provides electrical isolation between circuits while maintaining signal integrity for voice and data transmission.
• Features high shielding effectiveness achieved through interleaved trialloy cases and heavy copper shading rings.
• Designed for impedance matching and line balancing in telecommunications environments.

Applications

• Impedance matching in audio and telecommunication systems
• Isolation of data and voice signals on leased private lines
• Line balancing for balanced-to-unbalanced signal conversion

Procurement Notes

Verify that the specific unit matches the TY-300P designation to ensure correct 1:2 turns ratio and 600 Ohm impedance specifications. Confirm the pin terminal configuration aligns with the intended PCB layout requirements. Ensure compliance with relevant safety standards for isolation voltage ratings prior to integration into final equipment designs.

Selection Notes

Select this component when a 1:2 step-up ratio is required for voice or data coupling applications. Consider its physical dimensions and through-hole mounting style against available board space. Evaluate the shielding characteristics if electromagnetic interference mitigation is critical for the signal path integrity in the target application environment.

Part Context

The TY-300P belongs to the TY series of audio transformers manufactured by Triad Magnetics. This series is specifically engineered for telecommunications and audio signal processing tasks requiring reliable isolation and impedance transformation. The component serves as a standard solution for coupling devices in legacy and modern communication infrastructure where balanced signal handling is necessary.

Replacement Considerations

Cross-reference with other Triad Magnetics TY series models such as TY-402P for similar impedance requirements but different current ratings. Verify that substitute components maintain the 1:2 turns ratio and 600 Ohm impedance characteristics to ensure circuit compatibility without redesigning the surrounding passive network elements.
