MET-22-T

Audio Transformers Overview

The MET-22-T is an audio signal transformer manufactured by Triad Magnetics, designed for impedance matching applications. It features a primary impedance of 2500 ohms with a center tap and a secondary impedance of 2500 ohms with a center tap. The device supports a maximum DC resistance of 350 ohms on the secondary side and 280 ohms on the primary side. It has a power rating of 40 mW and operates up to a frequency of 100 kHz. The insulation withstands 1000 Vrms.

Audio Transformers Feature Summary

• Provides balanced impedance matching between two 2.5k ohm circuits with center taps
• Designed for high-voltage isolation with a 1000 Vrms rating
• Optimized for audio frequency signal transmission

Audio Transformers Applications

• Audio line level balancing and unbalancing
• Impedance matching in professional audio equipment
• Signal isolation in communication systems

Audio Transformers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may specify variations in winding configuration or mechanical dimensions. Confirm that the 2.5k ohm to 2.5k ohm center-tapped configuration matches the circuit requirements. Ensure the 40 mW power handling capacity is sufficient for the intended signal levels to prevent saturation or distortion during operation.

Audio Transformers Selection Notes

Select this component when a direct 1:1 impedance transformation between balanced lines is required. The 2.5k ohm center-tapped specification suits tube amplifier stages or specific professional audio interfaces. Consider the 1000 Vrms isolation rating for safety in high-voltage environments. Evaluate the 40 mW power limit against peak signal demands to ensure linear performance without core saturation.

Audio Transformers Part Context

The MET-22-T belongs to Triad Magnetics' portfolio of audio transformers, which are engineered for fidelity and reliability in signal processing. This model specifically addresses the need for balanced-to-balanced connections in audio chains. It complements other series like the MET-22-T-B, which offers data/voice coupling capabilities, providing options for different signal types within the same product family.

Audio Transformers Replacement Considerations

The MET-22-T-B is a related variant from Triad Magnetics offering data and voice coupling functionality. Verify if the specific encapsulation or application focus of the -B suffix is necessary. No other direct cross-manufacturer substitutes are confirmed in public documentation; design changes may be required for alternative components.
