TY-305P-B

Overview

The TY-305P-B is an audio transformer manufactured by Triad Magnetics, designed for signal transmission in voice and data applications. It features a 600:600 ohm impedance configuration with a 1:0.90 turns ratio. The device operates within a frequency range of 300 Hz to 3.5 kHz and supports a maximum DC current of 15 mA. Rated at 100 mW, it provides 1500 VAC insulation voltage between windings. The component utilizes radial pin terminal termination for through-hole PCB mounting.

Feature Summary

• Provides balanced audio signal transmission with matched 600 ohm primary and secondary impedances
• Ensures electrical isolation via 1500 VAC insulation rating between circuits
• Optimized for voice and data communication channels within specified frequency bandwidths

Applications

• Voice communication systems requiring balanced line interfacing
• Data transmission equipment utilizing standard telephony impedances
• Audio signal processing circuits needing galvanic isolation

Procurement Notes

Verify the specific suffix B against official Triad Magnetics documentation to confirm impedance ratios and frequency characteristics match design requirements. Ensure PCB layout accommodates radial pin spacing and that operating temperatures remain within the specified range. Cross-reference datasheet revision dates to validate insulation ratings and power handling capabilities before integration.

Selection Notes

Select this component when designing circuits requiring standard 600 ohm balanced audio interfacing with moderate power handling. Consider the 300 Hz to 3.5 kHz frequency response suitability for voice-band applications. Evaluate the through-hole mounting style against available board space and mechanical stress requirements during assembly.
