TY-401P

Overview

The Triad Magnetics TY-401P is a through-hole audio transformer designed for data and voice coupling applications. It features a single-channel configuration with a 600 Ohm primary impedance and a 600 CT secondary impedance. The unit supports a maximum DC current of 90 mA and operates within a frequency range of 300 Hz to 3.5 kHz. It provides an insulation voltage of 1.5 kV and functions reliably between -20°C and +85°C. The component measures 0.820 inches in length and 0.715 inches in width, utilizing radial pin terminals for mounting.

Feature Summary

• Provides electrical isolation and impedance matching for balanced audio circuits
• Supports line balancing and bridging configurations in signal transmission

Procurement Notes

Verify the specific part number suffix to ensure correct impedance configuration, as variations exist within the series. Confirm that the through-hole mounting style aligns with your PCB layout requirements. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal specifications before finalizing the procurement order.

Selection Notes

Select this component when a 600 Ohm to 600 CT transformation ratio is required for balanced audio signals. Consider the physical dimensions and through-hole mounting constraints during the design phase. Evaluate the frequency response characteristics to ensure compatibility with the intended voice or data bandwidth. Verify that the DC current rating is sufficient for the circuit's biasing requirements without saturation.

Part Context

The TY-401P belongs to the TY series of audio transformers manufactured by Triad Magnetics. This series is specifically engineered for high-quality audio signal transmission and isolation. The components are widely utilized in telecommunications and professional audio industries where reliable impedance matching and signal integrity are critical for performance.

Replacement Considerations

The TY-401P-B is a documented variant within the same product family. Verify that any substitute maintains the 600:600CT impedance ratio and through-hole mounting style to ensure mechanical and electrical compatibility.
