• Mu-metal screening can with lid to minimize magnetic interference
• High-quality construction suitable for professional audio markets

Applications

• Microphone input circuitry
• Professional audio equipment
• Audio signal transformation systems

Procurement Notes

Verify the specific part number VTX-102-003 against official Vigortronix documentation to confirm the presence of the Mu-metal can and lid. Ensure compatibility with PCB layout requirements for through-hole installation. Cross-reference impedance values (150 ohm primary, 6.25 kohm secondary) and frequency response (30 Hz to 25 kHz) with system specifications before procurement to guarantee correct functional performance in audio circuits.

Selection Notes

Select this component when designing microphone input stages that require galvanic isolation and impedance matching between low-impedance sources and higher-impedance loads. The inclusion of the Mu-metal shield makes it suitable for environments with potential electromagnetic interference. Consider the physical dimensions and through-hole pin configuration during PCB layout planning to ensure proper mechanical fit and electrical connectivity within the audio signal path.

Part Context

The VTX-102-003 belongs to the Vigortronix VTX series of audio transformers, which are characterized by their encapsulated PCB mounting style. This series targets the professional audio market, offering reliable performance for critical audio signal processing tasks. The specific model integrates shielding capabilities to maintain signal integrity, distinguishing it from standard unshielded audio transformers used in less sensitive electronic applications.

Replacement Considerations

Check for direct substitutes within the VTX series, such as variants with different impedance ratios or shielding options. Verify that any replacement maintains the 150 ohm primary and 6.25 kohm secondary impedance values. Ensure the alternative component supports the same 30 Hz to 25 kHz frequency range and through-hole mounting format to preserve circuit functionality without redesign.
