TY-403P-B

Overview

The Triad Magnetics TY-403P-B is a single-channel audio and signal transformer designed for through-hole mounting. It features a primary impedance of 600 Ohms and a secondary impedance of 600 Ohms, with a turns ratio of 1:2.21. The device operates within a frequency range of 300 Hz to 3.5 kHz and supports an insulation voltage of 1.5 kV. Maximum DC current rating is 90 mA. Physical dimensions are 41.91 mm in length, 34.93 mm in width, and a maximum height of 17.27 mm. Operating temperature ranges from -20°C to +85°C.

Feature Summary

• Provides electrical isolation and impedance matching between balanced lines
• Supports data and voice coupling applications
• Utilizes radial pin terminal termination for PCB integration

Applications

• Data/voice coupling circuits
• Impedance matching networks
• Line balancing systems
• Hybrid coil implementations

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm exact physical or electrical tolerances, as suffixes often denote packaging or minor mechanical variations. Ensure the required 1:2.21 turns ratio aligns with system design specifications. Confirm that the 600 Ohm impedance match is suitable for the target audio or data line interface requirements before finalizing procurement.

Selection Notes

Select this component when a 600 Ohm to 600 Ohm transformation with a 1:2.21 ratio is required for audio or data signals. The through-hole package is suitable for standard PCB assembly processes. Consider the 300 Hz to 3.5 kHz bandwidth limitation for high-fidelity audio applications. Verify that the 1.5 kV isolation voltage meets safety standards for the intended circuit environment.

Part Context

The TY-403P-B belongs to the Triad Magnetics TY series, which specializes in audio and signal transformers. This series is engineered for robust performance in communication and industrial control environments. The component serves as a critical interface element for balancing signals and isolating circuits while maintaining signal integrity across the specified frequency band.

Replacement Considerations

The TY-403P is a closely related variant within the same series. Verify if the base model TY-403P meets all mechanical and electrical requirements, including the specific 1:2.21 ratio and 600 Ohm impedances, before considering substitution.
