TTC-5029

Overview

The Tamura TTC-5029 is a telecommunications audio transformer designed for modem applications. It features a 600:600 ohm impedance ratio with primary and secondary DC resistances of 40 ohms each. The component operates within a frequency range of 200Hz to 4kHz, maintaining a maximum insertion loss of 1dB at 1kHz. It provides 1875VRMS isolation for one second and supports through-hole mounting via four pins. The unit functions reliably between 0°C and 70°C.

Feature Summary

• Provides balanced 600:600 ohm impedance transformation for telecommunication signal integrity
• Ensures electrical safety with high voltage isolation capabilities
• Supports standard through-hole PCB assembly processes

Applications

• Modem signal coupling circuits
• Telecommunications line interface modules
• Audio signal transmission systems

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to ordering, as supply chain conditions may vary. Confirm that the through-hole pin configuration matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental specifications. Cross-reference the impedance values with your circuit design to guarantee proper signal matching and performance stability.

Selection Notes

Select this component when a 600-ohm balanced interface is required for modem or telecom applications. The 40-ohm DC resistance per winding suits low-power signal transmission needs. Verify that the 200Hz-4kHz frequency response covers your specific audio bandwidth requirements. Consider the through-hole package size and pin spacing for mechanical integration into your enclosure design constraints.

Part Context

This part belongs to Tamura's audio and signal transformer series, specifically categorized under telecommunications transformers. It is distinct from power transformers and pulse transformers in its signal processing focus. The TTC-5029 serves as a passive component for impedance matching and isolation in communication hardware, differing from active signal conditioning devices.
