TY-142P

Overview

The TY-142P is a single-channel audio transformer manufactured by Triad Magnetics, designed for printed circuit board mounting. It features radial termination and operates within a frequency range of 200 Hz to 15 kHz. The device has a primary impedance of 600 ohms and a secondary impedance of 600 ohms. It supports a maximum DC current of 15 mA and handles up to 100 mW power. The insulation voltage is rated at 1.5 kV. Operating temperatures range from 0°C to +105°C. Physical dimensions are 20.6 mm in length, 17.8 mm in width, and 18.8 mm in height.

Feature Summary

• Designed for PCB mounting with fixed center spacing provided by plug-in terminals
• Provides electrical isolation and signal coupling between circuits
• Supports line matching applications with balanced 600-ohm impedances

Applications

• Telephone system coupling
• Line matching in audio equipment
• Interstage signal coupling
• Driver and output stage isolation

Procurement Notes

Verify the specific datasheet version to confirm the maximum DC current rating, as some sources cite 15 mA while others reference 90 mA or 4 mA for similar models. Ensure the operating temperature range aligns with the application environment, noting the specified limit of +105°C. Confirm that the physical footprint matches the PCB layout requirements given the radial pin configuration.

Selection Notes

Select this component when a 600-ohm to 600-ohm audio transformer is required for direct PCB integration. It is suitable for applications needing isolation between stages without requiring through-hole wave soldering. Consider the 200 Hz to 15 kHz bandwidth limitation against the signal frequency requirements. Verify that the 1.5 kV insulation voltage meets safety standards for the intended circuit isolation needs.

Part Context

The TY-142P belongs to the TY series of audio transformers produced by Triad Magnetics. This series is characterized by PC mount designs intended for compact electronic assemblies. These components are commonly utilized in telecommunications and professional audio gear where space efficiency and reliable signal transfer are critical design factors.

Replacement Considerations

The TY-145P is a documented alternative within the same manufacturer's lineup, offering identical 600:600 impedance ratios but differing in maximum DC current ratings and specific frequency response characteristics.
