Overview
The Triad Magnetics TY-301P is a through-hole audio transformer designed for data and voice coupling applications. It features a primary impedance of 600 Ohms and a secondary impedance of 900 Ohms, providing an impedance ratio of 1:1.27. The component operates within a frequency range of 300 Hz to 3.5 kHz. It offers longitudinal balance performance of 45 dB at frequencies between 1000 Hz and 4000 Hz, and 60 dB at frequencies between 200 Hz and 1000 Hz. The unit utilizes wire leads for termination and is intended for chassis or panel mounting configurations in professional audio systems.
Feature Summary
- Provides balanced signal coupling with specified longitudinal balance characteristics
- Features dual winding configuration optimized for audio frequency ranges
- Supports direct wire lead termination for flexible installation
Applications
- Professional audio signal transmission
- Voice communication system coupling
- Data line balancing circuits
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as TY-301P-B may exist with distinct electrical parameters. Confirm that the required longitudinal balance metrics align with the standard TY-301P specifications provided in official datasheets. Ensure compatibility with existing circuit board layouts or chassis mounting requirements before finalizing procurement decisions.
Selection Notes
Select this component when a 600 Ohm to 900 Ohm impedance transformation is required for audio applications. Consider the operating frequency range of 300 Hz to 3.5 kHz to ensure suitability for the target signal bandwidth. Evaluate the physical dimensions and through-hole mounting style against available space constraints in the design.
Part Context
This component belongs to the Triad Magnetics audio transformer series, which includes various models like the TY-300P and TY-307P. These parts are generally utilized in professional audio environments requiring reliable signal isolation and impedance matching. The manufacturer provides comprehensive technical documentation for each variant to support engineering integration.
Replacement Considerations
The TY-301P-B is a documented variant within the same product family. Verify if the B-suffix denotes identical electrical characteristics or specific modifications before substituting. Cross-reference pinouts and mechanical dimensions to ensure interchangeability without redesigning the host assembly.
