Overview
The Tamura MET-41 is a through-hole audio transformer designed for signal coupling applications. It features a primary impedance of 300 ohms and a secondary impedance of 600 ohms, providing a specific impedance transformation ratio for circuit integration. The component supports an isolation voltage of 500 Vrms, ensuring electrical safety between windings. It operates within a temperature range of -20°C to 85°C and utilizes a pin termination style for standard PCB mounting.
Feature Summary
- Through-hole construction for reliable PCB mounting
- Audio frequency signal coupling capability
- High potential insulation for circuit isolation
Applications
- Audio signal coupling in electronic circuits
- Impedance matching between stages
- Signal isolation in audio equipment
Procurement Notes
Verify the exact datasheet version from Tamura or authorized distributors before implementation. Confirm that the 300-ohm primary and 600-ohm secondary impedances match the target circuit requirements. Ensure the 500Vrms isolation rating meets the system's safety standards. Check the operating temperature range against environmental conditions.
Selection Notes
Select this component when a fixed 300-to-600 ohm impedance transformation is required in audio paths. The through-hole package suits designs prioritizing mechanical stability over high-density surface mount layouts. Verify that the 500Vrms isolation is sufficient for the specific application voltage levels.
Part Context
The MET-41 belongs to the MET series of audio transformers manufactured by Tamura. This series typically includes various models with different impedance ratios and packaging options. The MET-41 specifically addresses applications requiring a step-up impedance configuration with robust isolation characteristics.
Replacement Considerations
No direct substitute part numbers are confirmed in the provided documentation. Cross-reference with other Tamura MET series models if impedance ratios differ. Consult manufacturer guidelines for any updated equivalents.
