TY-304P

Overview

The TY-304P is an audio and signal transformer manufactured by Triad Magnetics, designed for PCB mounting applications. It features a single channel with dual primary and dual secondary windings configured for 600 ohm center-tapped to 600 ohm center-tapped impedance matching. The device operates within a frequency range of 200 Hz to 15 kHz and supports a maximum DC current of 15 mA in the primary winding. Rated for 100 mW power handling, it provides 1.5 kV insulation voltage and functions reliably between 0°C and +105°C.

Feature Summary

• Provides precise 600 ohm center-tapped to 600 ohm center-tapped impedance transformation for balanced audio lines
• Supports simultaneous AC signal and DC bias currents up to 15 mA for active circuit integration
• Ensures electrical isolation with a 1.5 kV insulation rating between windings
• Utilizes radial through-hole termination for secure printed circuit board installation

Applications

• Telecommunications equipment requiring balanced line coupling
• Audio signal processing circuits with balanced input/output stages
• Data transmission interfaces utilizing 600 ohm standard impedances
• Professional audio mixing consoles and signal routing hardware

Procurement Notes

Verify that the specific procurement order matches the exact model designation TY-304P to ensure correct impedance configuration. Confirm that the application environment remains within the specified operating temperature range of 0°C to +105°C. Ensure PCB layout accommodates the radial pin spacing and physical dimensions provided in the official datasheet. Check for compliance requirements relevant to the end-use industry, such as FCC regulations for telecommunications equipment.

Selection Notes

Select this component when a balanced 600 ohm to 600 ohm audio interface is required with integrated DC bias capability. The radial package suits designs needing robust mechanical anchoring on standard PCBs. Consider the 1.5 kV isolation if galvanic separation between signal stages is necessary. Evaluate the 200 Hz to 15 kHz bandwidth against the specific frequency response needs of the audio or data signal path to ensure minimal attenuation within the operational spectrum.
