TTC-5012

Overview

The Tamura TTC-5012 is a telecommunications audio transformer designed for signal coupling in data and voice applications. It features a 600:600 ohm impedance ratio with a 1:1 turn configuration. The component operates within a frequency range of 200 Hz to 4 kHz, ensuring effective transmission across standard telecommunication bands. Key electrical specifications include a maximum insertion loss of 1.0 dB and a return loss of -76 dB at the case. The device supports a common mode rejection ratio of 60 dB and maintains total harmonic distortion below 31% under specified conditions.

Feature Summary

• Provides balanced signal coupling between 600-ohm lines
• Ensures high fidelity transmission with low insertion loss
• Offers strong isolation against common mode interference

Applications

• Telecommunications line interfacing
• Data modem signal processing

Procurement Notes

Verify the specific termination style and package variant required for your PCB layout before ordering. Confirm that the impedance matching aligns with your circuit design requirements. Check for any specific compliance certifications needed for your target market. Ensure the operating temperature range meets your environmental constraints. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or pin configurations.

Selection Notes

Select this component when a precise 600-ohm balanced interface is required for telecommunication signals. Consider the tight tolerance on insertion loss if signal integrity is critical. Evaluate the common mode rejection capabilities against potential noise environments in your application. Compare physical package dimensions against available board space constraints.
