Audio Transformers Procurement Notes
Verify the specific manufacturer part number against official Tamura documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters, including the 25k:600 Ohm impedance ratio and 300Hz-100kHz frequency response. Check for physical integrity of the through-hole leads and ensure compliance with relevant safety isolation standards prior to integration into final assemblies.
Audio Transformers Selection Notes
Select this component when interfacing circuits requiring a 25,000 Ohm primary to 600 Ohm secondary impedance transformation. It is appropriate for applications operating within the 300Hz to 100kHz bandwidth. Consider the through-hole package constraints and verify that the physical footprint aligns with the target PCB design requirements before procurement.
