MET-09

Audio Transformers Overview

The Tamura MET-09 is a through-hole audio transformer designed for data and voice coupling applications. It features a primary impedance of 10kCT ohms and a secondary impedance of 10kCT ohms, providing a 1:1 turns ratio. The device operates within a frequency range of 300Hz to 100kHz with a frequency response tolerance of ±2dB. Electrical specifications include a maximum DC resistance of 1000 ohms on the primary side and an isolation voltage rating of 500VRMS applied for 30 seconds. The component supports a power level of 40mW and functions within a temperature range of -20°C to 85°C.

Audio Transformers Procurement Notes

Verify that the specific order matches the MET-09 designation from Tamura Corporation. Confirm that the required impedance configuration aligns with the 10kCT primary and secondary specifications. Ensure the application environment remains within the specified operating temperature limits. Check for compliance requirements such as RoHS status if necessary for the target market. Validate physical dimensions against the PCB layout constraints before finalizing procurement.

Audio Transformers Selection Notes

Select this component when a 1:1 impedance transformation is required for balanced audio or data lines. The 10kCT winding configuration suits high-impedance source and load matching scenarios. Consider the through-hole package type for mechanical stability in industrial environments. Evaluate the 500VRMS isolation rating against system safety requirements. Ensure the 300Hz lower frequency limit meets the lowest signal frequency needs of the design.
