TTC-03

Overview

The Tamura TTC-03 is an audio and signal transformer designed for telecommunications applications. It features a primary impedance of 600 Ohms center-tapped and a secondary impedance of 600 Ohms center-tapped. The device operates within a frequency range of 300 Hz to 3.5 kHz with a turns ratio of 1:1.06. It utilizes a through-hole mounting style and belongs to the TTC series.

Feature Summary

• Designed for modem and telecom signal coupling
• Provides electrical isolation between circuit stages
• Supports standard telephone line impedances

Applications

• Modem interface circuits
• Telecommunications equipment

Procurement Notes

Verify the specific datasheet revision when ordering, as documentation may vary across distributors. Confirm that the component meets RoHS compliance requirements for your project. Ensure the through-hole footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a 600 Ohm center-tapped configuration is required for audio or low-frequency signal transmission. The 300 Hz to 3.5 kHz bandwidth suits voice-band applications. Consider the physical size and through-hole installation method during layout planning.

Part Context

The TTC-03 is part of Tamura's broader TTC series of audio and signal transformers. This series includes variants like the TTC-02 and TTC-5036, which offer different impedance ratios and DC resistance values. These components are specialized for telecom and modem applications requiring precise impedance matching.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative models from other manufacturers.
