TTC-5020

Overview

The Tamura TTC-5020 is a through-hole audio and signal transformer designed for data and voice coupling applications. It features a primary impedance of 600 Ohms and a secondary impedance of 301 Ohms, providing a 1:1 transformation ratio. The component operates within a frequency range of 300Hz to 3.5kHz with an insertion loss specification. It supports a maximum current of 65mA and offers high isolation capability rated at 1500Vrms or 1875VRMS depending on test conditions.

Feature Summary

• Provides galvanic isolation between circuit sections via transformer coupling
• Optimized for balanced audio and voice signal transmission
• Designed for standard through-hole PCB mounting configurations

Applications

• Voice modem line interfacing
• Telecommunications equipment signal coupling
• Audio interface circuits requiring impedance matching

Procurement Notes

Verify the specific datasheet version to confirm isolation voltage ratings, as sources indicate variations between 1500Vrms and 1875VRMS. Ensure the procurement channel provides the official Tamura documentation to validate the 600:301 Ohm impedance ratio and 65mA current limits. Confirm that the through-hole package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a 1:1 impedance transformation between 600 Ohm and 301 Ohm lines is required for voice or data signals. It is suitable for applications needing robust isolation in telecommunications environments. Consider the 300Hz to 3.5kHz bandwidth constraints to ensure compatibility with the intended signal frequencies. Verify thermal and current handling capabilities against the 65mA maximum rating.
