TY-400P-B

Overview

The Triad Magnetics TY-400P-B is an audio and signal transformer designed for data and voice coupling applications. It features a single channel with radial termination and operates within a frequency range of 300 Hz to 3.5 kHz. The unit has a primary impedance of 600 Ohms and a secondary impedance of 600 Ohms, supporting a maximum DC current of 90 mA. It provides 1.5 kV insulation voltage and functions in temperatures from -20°C to +85°C. Dimensions are 1.25 inches in length, 0.815 inches in width, and 0.53 inches in height.

Feature Summary

• Designed for data and voice coupling on leased private lines or dial-up systems
• Provides electrical isolation with 1.5 kV insulation voltage rating
• Supports standard 600 Ohm line impedance matching for both primary and secondary windings

Applications

• Data transmission line coupling
• Voice communication system interfacing
• Leased private line equipment integration

Procurement Notes

Verify the specific suffix 'B' against manufacturer documentation to confirm packaging variations or minor mechanical differences compared to the base model. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when 600 Ohm impedance matching is required for audio or data signals. Confirm that the operating temperature range of -20°C to +85°C meets environmental specifications. Verify physical space constraints against the specified dimensions for proper board layout integration.

Part Context

This part belongs to the TY series of audio transformers manufactured by Triad Magnetics. These components are specialized for telecommunications and industrial control environments requiring reliable signal transfer between circuits with matched impedances.

Replacement Considerations

The TY-402P is a documented alternative within the same series offering similar impedance characteristics but with a different frequency range of 300 Hz to 3.5 kHz and FCC68 compliance.
