Audio Transformers Procurement Notes

Verify the specific datasheet version when sourcing to confirm current manufacturing status and compliance details. Ensure that the through-hole package dimensions align with the target PCB layout constraints. Confirm that the 1 kV isolation rating meets the safety requirements of the intended application environment. Cross-reference the 50 mW power handling capability against peak signal levels to prevent saturation or damage during operation.

Audio Transformers Selection Notes

Select this component when a 600-ohm balanced interface is required for audio or low-frequency data signals. The wide frequency response up to 100 kHz makes it suitable for voice band applications. Consider the physical size and through-hole mounting style if surface-mount alternatives are not feasible. Verify thermal performance within the specified -20°C to +85°C range for the operating environment.

Audio Transformers Part Context

The MET-32 belongs to the MET series of audio transformers manufactured by Tamura. This series is specifically engineered for coupling applications in telecommunications and audio processing. The component utilizes a wound transformer design rather than integrated circuit technology, providing passive signal transfer with galvanic isolation between input and output stages.

Audio Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor catalogs for direct replacements or verify compatibility with equivalent 600-ohm audio transformers from other manufacturers based on pinout and electrical specifications.
