TY-311P-B

Overview

The Triad Magnetics TY-311P-B is a through-hole audio transformer designed for data and voice coupling applications. It features a primary impedance of 600 ohms and a secondary impedance of 600 ohms, with a turns ratio of 1:1.05. The device operates within a frequency range of 300Hz to 3.5kHz, maintaining a frequency response of ±0.5dB. Electrical specifications include a standard insertion loss of 1dB and an echo loss of 26dB. The unit provides 1500VAC isolation and supports a power level from -45dB to 7dB. Physical dimensions are 20.62mm in length, 18.16mm in width, and a maximum height of 18.80mm.

Feature Summary

• Provides galvanic isolation between circuits with a 1500VAC rating
• Designed for impedance matching and line balancing in audio systems
• Utilizes PC pin termination for reliable through-hole mounting

Applications

• Impedance matching in telecommunication lines
• Isolation in audio signal processing circuits
• Line balancing for balanced-to-unbalanced conversion
• Hybrid coil implementations in communication equipment

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm physical or electrical distinctions from the base model. Ensure the ordering quantity aligns with the distributor's standard packaging configuration. Cross-reference the component marking with the official Triad Magnetics documentation to prevent substitution errors during assembly.

Selection Notes

Select this component when a 600-ohm to 600-ohm transformation is required for voice-band frequencies. The through-hole package suits prototyping and high-reliability industrial environments. Confirm that the operating temperature range of -20°C to 85°C meets the environmental requirements of the target application before integration.

Part Context

This part belongs to the Triad Magnetics TY series, which specializes in audio and data coupling transformers. The series is engineered for robust performance in telecommunications and broadcast applications. The TY-311P-B variant maintains the core electrical characteristics of the series while adhering to specific manufacturing standards for voice-grade signal transmission.

Replacement Considerations

The TY-311P is a direct functional equivalent with identical electrical parameters. Verify if the 'B' suffix denotes a specific packaging or compliance update rather than a change in circuit function.
