VTX-102-3001

Overview

The Vigortronix VTX-102-3001 is a high-quality audio transformer designed for through-hole PCB mounting. It features a 1:1 winding ratio and a primary impedance of 600 ohms with a secondary impedance of 30 ohms. The device operates within a frequency range of 20Hz to 30kHz. Technical specifications include a nominal inter-winding capacitance of 109pF measured at 1kHz and 0.3V, and a common mode rejection ratio (CMRR) of less than 60dB at 10kHz.

Feature Summary

• Provides galvanic isolation for audio signals with a 1:1 turns ratio
• Encapsulated construction suitable for printed circuit board installation
• Designed to minimize interference with optional MU-metal shielding

Applications

• Microphone input circuitry
• Audio signal transmission systems
• Balanced line interfacing

Procurement Notes

Verify the specific datasheet version from Vigortronix or authorized distributors to confirm current manufacturing status and exact physical dimensions. Ensure that the through-hole pin configuration matches the target PCB footprint. Cross-reference the 600-ohm impedance requirements with the system design to guarantee compatibility with existing audio interfaces.

Selection Notes

Select this component when a 1:1 audio isolation transformer is required for 600-ohm systems. Consider the encapsulated form factor for automated assembly processes. Evaluate the CMRR specification against noise sensitivity requirements in the application environment. Confirm that the 20Hz to 30kHz frequency response aligns with the intended audio bandwidth needs.

Part Context

This part belongs to the Vigortronix VTX series of PCB-mounted audio transformers. These components are engineered for reliable performance in professional audio equipment. The series offers various impedance options and winding ratios to suit different signal processing applications. Encapsulation ensures durability and protection against environmental factors during operation.

Replacement Considerations

Consult official Vigortronix documentation for direct cross-references. Verify that any substitute maintains the 1:1 ratio, 600-ohm primary impedance, and compatible mounting style.
