Audio Transformers datasheet and documents for MET-04

MET-04

Audio Transformers Overview

The Tamura MET-04 is a through-hole audio transformer designed for signal coupling applications. It features a primary impedance of 50k Ohms and a secondary impedance of 1k Ohms, split into two windings. The device supports a turns ratio of 14.1:1:1 and operates within a frequency range of 300Hz to 100kHz. It is rated for a maximum power dissipation of 25mW at the primary side. The component utilizes a split secondary configuration to facilitate balanced signal transmission in audio circuits.

Audio Transformers Feature Summary

Provides electrical isolation between audio signal stages
Supports balanced output via split secondary winding
Optimized for wideband audio frequency response

Audio Transformers Applications

Audio signal coupling in professional equipment
Telecommunications interface circuits
Balanced line driver/receiver stages

Audio Transformers Procurement Notes

Verify that the ordered component matches the specific Tamura MET-04 audio transformer specifications. Confirm the package type and pinout alignment with design requirements. Ensure the supplier provides valid documentation confirming the manufacturer origin and technical compliance. Cross-reference the part number to distinguish from unrelated fuse products sharing similar alphanumeric sequences.

Audio Transformers Selection Notes

Select this component when a high-impedance primary to low-impedance secondary transformation is required for audio signals. The 50k to 1k Ohm ratio suits specific source and load matching needs. Consider the through-hole mounting style and physical footprint constraints during PCB layout. Evaluate the frequency response requirements against the 300Hz to 100kHz operational range.

Audio Transformers Part Context

The MET-04 belongs to the TAMURA MET series of audio transformers. This series includes various models such as MET-39 and MET-09, which differ in impedance ratios and winding configurations. The MET-04 specifically addresses applications requiring a 50k primary impedance with a split 1k secondary output, distinguishing it from other series members like the MET-35 or MET-09.
