TTC-129

Overview

The Tamura TTC-129 is a telecom coupling transformer designed for data and voice applications. It features a split secondary configuration with primary and secondary impedances of 600 Ohms each. The component exhibits a frequency response tolerance of ±0.5dB, ensuring signal integrity across operational bands. Physical dimensions are specified as 32.30mm in length and 33.00mm in width. The secondary DC resistance is rated at 190 Ohms. Termination is achieved via PC pin style connections, suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Provides impedance matching between 600 Ohm lines for maximum power transfer
• Supports combined data and voice transmission signals
• Utilizes split secondary winding architecture

Applications

• Telecommunications line coupling
• Data transmission interface circuits
• Voice communication equipment

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon order confirmation, as production batches may vary. Confirm that the PC pin termination style matches the target PCB footprint dimensions of 32.30mm by 33.00mm. Ensure the supplier provides official Tamura documentation to validate the 600/600 Ohm impedance specification and 190 Ohm secondary DC resistance values.

Selection Notes

Select this component when a 600 Ohm balanced-to-balanced isolation solution is required for telecom infrastructure. The split secondary design facilitates specific circuit topologies requiring center-tapped or separated secondary outputs. Consider the physical size constraints of the enclosure, as the unit measures over 32mm in both length and width. Verify compatibility with the operating frequency range defined by the ±0.5dB response curve.

Part Context

The TTC-129 belongs to the Tamura TTC series, which focuses on high-quality audio and signal transformers. This series emphasizes efficient power transfer during impedance matching operations. The product is categorized under audio and signal transformers, specifically tailored for telecommunications environments where reliable signal coupling between network segments is critical.

Replacement Considerations

Publicly confirmed substitute part numbers for the TTC-129 are not available in the provided documentation. Users must verify electrical compatibility, including the 600 Ohm impedance ratio and 190 Ohm secondary DC resistance, if considering alternative manufacturers.
