MET-35

Audio Transformers Overview

The Tamura MET-35 is a through-hole audio transformer designed for data and voice coupling applications. It features a primary impedance of 600CT ohms and a secondary impedance of 8 ohms, resulting in a turns ratio of 8.66:1. The device operates within a frequency range of 300Hz to 100kHz with a response tolerance of ±2dB. Key electrical specifications include a primary DC resistance of 60 ohms and a secondary DC resistance of 1.5 ohms. It supports a power rating of 50mW and provides 1000VRMS isolation for 30 seconds. The component measures 10.40mm x 7.87mm x 11.80mm max and functions between -20°C and 85°C.

Audio Transformers Procurement Notes

Verify the specific manufacturer part number MET-35 against official Tamura documentation to confirm pinout orientation and impedance ratings. Ensure that the selected supplier provides valid RoHS compliance certificates and material declarations. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards and environmental regulations before finalizing procurement orders.

Audio Transformers Selection Notes

Select this component when a 600CT primary impedance is required for standard audio lines paired with an 8-ohm secondary load. The 300Hz to 100kHz bandwidth makes it appropriate for voice-grade applications rather than high-fidelity music reproduction. Consider the through-hole package constraints and physical dimensions to ensure adequate clearance on the target printed circuit board layout.

Audio Transformers Part Context

The MET-35 belongs to the MET series of miniature encapsulated transformers manufactured by Tamura. This series focuses on compact form factors for telecommunications and audio coupling needs. The component utilizes standard winding techniques to achieve tight coupling and low leakage inductance within a robust epoxy-encapsulated housing suitable for industrial environments.

Audio Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by matching primary/secondary impedances, frequency response curves, and physical footprint dimensions before considering alternative components.
