TTC-198

Overview

The Tamura TTC-198 is a telecommunications audio transformer designed for signal coupling applications. It features a primary impedance of 600 ohms and a secondary configuration of 600 ohms center-tapped (CT). The device provides an isolation voltage rating of 4000 VRMS when tested for one minute, ensuring electrical safety between circuits. This component facilitates balanced audio transmission in telecommunication systems.

Feature Summary

• Provides galvanic isolation between circuit stages
• Supports balanced audio signal transmission
