Overview
The Tamura TTC-5007 is a voice and modem line transformer designed for signal coupling applications. It features a primary impedance of 600 Ohms and a secondary impedance of 530 Ohms. The component utilizes a through-hole mounting style, suitable for standard PCB assembly processes. Key electrical specifications include a maximum DC resistance of 60 Ohms and a total harmonic distortion (THD) performance of -83 dB when measured under case conditions. These parameters define its operational characteristics in audio and data transmission circuits.
Feature Summary
- Provides galvanic isolation between primary and secondary circuit lines
- Supports voice and modem signal transmission with defined impedance matching
- Constructed for through-hole printed circuit board integration
Applications
- Voice communication line interfacing
- Modem signal coupling circuits
- Audio transformer applications requiring specific impedance ratios
Procurement Notes
Verify the specific datasheet revision and safety certifications such as UL1950 or EN60950 compliance before finalizing procurement decisions. Confirm that the through-hole package dimensions align with the target PCB footprint. Ensure the supplier provides documentation confirming RoHS status and lead-free manufacturing processes to meet regulatory requirements for the intended market deployment.
Selection Notes
Select this component when a 600:530 Ohm impedance transformation ratio is required for voice or modem lines. Consider the through-hole form factor if surface-mount alternatives are unsuitable for the mechanical constraints. Evaluate the maximum DC resistance and THD specifications against the system's signal integrity requirements to ensure adequate performance in the specific application environment.
Part Context
The TTC-5007 belongs to Tamura's series of audio and signal transformers, specifically categorized for voice and modem line applications. This series includes related models such as the TTC-5006 and TTC-5009, which share similar functional categories but may differ in impedance ratios or physical packaging. These components are engineered to provide reliable signal coupling in telecommunications equipment.
Replacement Considerations
Publicly confirmed substitute part numbers for the TTC-5007 were not identified in the provided source material. Users should consult official Tamura documentation or authorized distributors for verified cross-reference information.
