MET-49

Audio Transformers Overview

The MET-49 is a through-hole audio transformer manufactured by Tamura. It features a primary impedance of 600 Ohms and a secondary impedance of 600 Ohms with center tap configuration. The device operates within a frequency range of 300Hz to 100kHz. It utilizes a 1.41:1:1 turns ratio and is designed for telecom and audio signal applications. The component is RoHS compliant and employs PC pin mounting.

Audio Transformers Feature Summary

• Provides balanced-to-unbalanced or unbalanced-to-balanced signal conversion via center-tapped secondary winding
• Ensures electrical isolation between primary and secondary circuits
• Supports standard telephone line impedance matching requirements

Audio Transformers Applications

• Telecommunications equipment interface circuits
• Audio signal processing systems
• Balanced line termination networks

Audio Transformers Procurement Notes

Verify the specific datasheet version to confirm impedance tolerances and DC resistance values, as distributor listings may vary in detail. Ensure the ordering suffix matches the required lead frame or packaging specification if applicable. Confirm RoHS compliance status directly from the manufacturer's official documentation prior to integration into regulated environments.

Audio Transformers Selection Notes

Select this component when a 600-ohm impedance match is required for analog audio or telephony signals. The through-hole package suits prototyping or high-reliability mechanical assembly needs. Consider the 300Hz lower frequency limit for voice band applications rather than full-range audio fidelity.

Audio Transformers Part Context

Tamura produces specialized magnetic components for communication infrastructure. The MET series typically addresses legacy telecom standards requiring precise impedance transformation. This model serves as a passive linear component within larger signal conditioning assemblies.

Audio Transformers Replacement Considerations

Cross-reference part numbers such as MET-59 for similar 600-ohm configurations. Verify physical footprint compatibility and pinout alignment before substitution. Consult official Tamura documentation for direct equivalent recommendations.
