MET-59-T

Overview

The Triad Magnetics MET-59-T is a through-hole audio transformer designed for data and voice coupling applications. It features a primary impedance of 600 ohms and a secondary configuration of 150/150 ohms with a center tap, resulting in a 2:1:1 turns ratio. The component operates within a frequency range of 300 Hz to 100 kHz and supports a power rating of 50 mW. It withstands an input voltage of 230 volts and offers high isolation with a 1 kVrms rating. The unit measures 10.40 mm by 7.87 mm and functions reliably between -20°C and 85°C.

Feature Summary

• Provides precise impedance matching for balanced audio and data signal transmission
• Ensures electrical isolation between circuits with high dielectric strength
• Supports voice and data coupling in telecommunications environments

Applications

• Telecommunications line interface circuits
• Balanced audio signal transmission systems
• Data communication equipment requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'T' to confirm through-hole mounting and bulk packaging specifications. Ensure the procurement matches the exact impedance ratio of 600 to 150/150 ohms required for the circuit design. Confirm RoHS compliance status and operating temperature range alignment with environmental requirements before finalizing orders.

Selection Notes

Select this component when a 2:1:1 turns ratio is necessary for interfacing 600-ohm lines with 150-ohm balanced loads. Consider the physical dimensions and through-hole mounting style for PCB layout constraints. Evaluate the frequency response characteristics to ensure compatibility with the intended audio or data bandwidth requirements.

Part Context

This component belongs to the Triad Magnetics audio transformer series, which focuses on high-reliability magnetic components for demanding designs. The MET-59-T variant specifically addresses applications requiring balanced-to-balanced conversion with defined impedance ratios. It serves as a critical passive element in maintaining signal integrity across coupled circuits.

Replacement Considerations

Direct substitutes include the MET-59 from Tamura Corporation, which shares similar telecom transformer characteristics. Verify that alternative sources maintain the identical 600/150:150 impedance ratio and 2:1:1 turns ratio to ensure circuit compatibility without modification.
