VTX-134-002

Overview

The VTX-134-002 is a surface-mount audio transformer with a 1:1 turns ratio. It features a primary impedance of 600 ohms and an additional specification of 111 ohms. The device supports a frequency range up to 400 kHz and provides 4 kV isolation voltage. Designed for PCB SMT applications, it offers low profile construction suitable for compact electronic designs requiring line matching or isolation.

Feature Summary

• Surface-mount technology (SMT) construction for automated PCB assembly
• Low profile design optimized for space-constrained electronic equipment
• High safety isolation capability rated at 4 kV
• Functionality as a line matching and isolation transformer

Applications

• PCB SMT audio applications
• Line matching circuits
• Signal isolation in electronic devices

Procurement Notes

Verify the specific datasheet version when sourcing, as impedance specifications may vary between 600 ohm and 111 ohm descriptions across different distributor listings. Confirm that the 4 kV isolation rating aligns with your safety compliance requirements. Ensure the surface-mount package dimensions fit your board layout constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring galvanic isolation in audio signal paths without voltage transformation. The 1:1 ratio maintains signal level while providing noise reduction through isolation. Consider the 400 kHz bandwidth limit to ensure compatibility with the intended signal frequencies. The low-profile SMT form factor is critical for modern compact device designs.

Part Context

This component belongs to the Vigortronix VTX series of PCB-mounted transformers. The series includes various power supply units and audio transformers designed for industrial and consumer electronics. The VTX-134-002 specifically addresses audio signal integrity needs within this product family.

Replacement Considerations

Cross-reference tools indicate parametrically similar parts are available. Verify that any substitute matches the 1:1 ratio, 600 ohm impedance, and 4 kV isolation rating. Ensure the replacement also supports SMT mounting and comparable frequency response up to 400 kHz.
