VTX-101-003

Overview

The VTX-101-003 is an encapsulated audio transformer from Vigortronix, designed for through-hole PCB mounting. It features a turn ratio of 1:6.45 and operates within a frequency range of 30Hz to 25kHz. The component has a primary impedance of 150 ohms and a secondary impedance of 3.25k ohms (or 6.25k ohms per some listings). It includes an optional MU-metal can with lid to minimize external noise interference.

Feature Summary

• Encapsulated construction for robust PCB mounting
• Optional MU-metal shielding to reduce external electromagnetic interference
• High-quality audio performance with specified impedance matching

Applications

• Audio signal isolation
• Impedance matching in audio circuits
• Noise reduction in sensitive audio equipment

Procurement Notes

Verify the exact secondary impedance specification (3.25k vs 6.25k ohms) against the specific datasheet revision or manufacturer confirmation prior to procurement, as conflicting values appear in public listings. Ensure the required shielding option (MU-metal can) is selected if noise immunity is critical for the application design.

Selection Notes

Select this component when a 1:6.45 turn ratio and 150-ohm primary impedance are required for audio applications. Consider the optional MU-metal shielding if the operating environment has significant electromagnetic interference. Confirm the frequency response requirement aligns with the 30Hz to 25kHz operational range provided by the manufacturer.

Part Context

This part belongs to the Vigortronix VTX series of audio transformers, which are characterized by encapsulated PCB mounting options. The series is designed to provide stable performance in electronic equipment designs where transformer characteristics directly impact system stability and efficiency.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Vigortronix VTX models only if electrical parameters match exactly.
