MET-17

Audio Transformers Overview

The Tamura MET-17 is a miniature encapsulated audio transformer designed for data and voice coupling applications. It features a primary impedance of 10kCT ohms and a secondary impedance of 500CT ohms, resulting in a turns ratio of 4.47:1. The component operates within a frequency range of 300Hz to 100kHz with a frequency response tolerance of ±2dB. It supports an isolation voltage of 500VRMS at 30 seconds and handles a power level of 40mW. The device utilizes through-hole mounting with PC pin termination and functions within a temperature range of -20°C to 85°C.

Audio Transformers Procurement Notes

Verify the specific manufacturer part number MET-17 against official Tamura documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters, including the 10kCT primary impedance and 500CT secondary impedance. Check for RoHS compliance status and ensure the package type corresponds to the through-hole configuration described in the datasheet before integration into production lines.

Audio Transformers Selection Notes

Select this component when designing circuits requiring precise impedance matching between 10kCT and 500CT levels for audio or data signals. Ensure the operating environment stays within the specified -20°C to 85°C temperature range. Consider the physical dimensions of 10.40mm x 7.87mm for board space constraints. Verify that the required isolation voltage of 500VRMS meets the safety requirements of the target application.
