Audio Transformers Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm current compliance status and mechanical dimensions. Ensure that the through-hole lead configuration matches the target PCB footprint design requirements before finalizing procurement orders.

Audio Transformers Selection Notes

Select this component when a 1:1 impedance match between 600-ohm lines is required for voice or low-frequency data signals. Consider the 3.5 kHz upper frequency limit for bandwidth constraints. Evaluate the physical package dimensions against available board space and verify thermal operating conditions align with the application environment.

Audio Transformers Part Context

The MET-46 belongs to the MET series of audio transformers manufactured by Tamura. This series focuses on components suitable for telecommunications and signal processing environments where precise impedance matching and signal integrity are critical for maintaining clear voice and data transmission quality.

Audio Transformers Replacement Considerations

The MET-46-T from Triad Magnetics is listed as a comparable alternative in distributor catalogs. Verify pinout compatibility and exact frequency response specifications before substitution.
