TY-400P

Overview

The TY-400P is a data and voice coupling audio transformer manufactured by Triad Magnetics. It features a single channel with radial pin terminals for through-hole mounting. The device operates within a frequency range of 300 Hz to 3.5 kHz. Primary and secondary coil impedances are both rated at 600 Ohms, providing a 1:1.07 transformation ratio. The unit supports a maximum DC current of 90 mA and offers an insulation voltage of 1.5 kV. Physical dimensions are 1.25 inches in length, 0.815 inches in width, and 0.53 inches in height.

Feature Summary

• Designed specifically for data and voice coupling applications over leased private lines or dial-up connections
• Provides impedance matching, isolation, line balancing, bridging, and hybrid functions
• Constructed with unshielded components utilizing radial pin terminal connections

Applications

• Data and voice coupling for telecommunications systems
• Impedance matching in audio signal circuits
• Line balancing and bridging operations
• Isolation in leased private line access networks

Procurement Notes

Verify the specific datasheet version for the TY-400P to confirm compliance with FCC Part 68 requirements if used in telephony equipment. Ensure that the radial pin terminal spacing matches the target PCB layout before finalizing procurement. Confirm that the operating temperature range of -20°C to +85°C aligns with the intended environmental conditions of the assembly.

Selection Notes

Select the TY-400P when a 600 Ohm to 600 Ohm audio transformer is required for data or voice signal transmission. This component is suitable for designs needing isolation between circuit stages without magnetic shielding. Consider the physical size constraints as the unit measures approximately 1.25 inches in length. Verify that the 90 mA DC current rating meets the biasing requirements of the connected circuitry.
