Overview
The Tamura TTC-142-2 is a telecom modem transformer designed for wet coupling applications. It features a primary impedance of 600 Ohms and a secondary impedance of 600 Ohms. The device provides an isolation ratio of 1:1.41/1:1 with a DC resistance (DCR) of 75 Ohms on the primary side and 95 Ohms on the secondary side. Constructed as a four-terminal component, it utilizes through-hole PC pin termination for reliable circuit board integration.
Feature Summary
- Provides electrical isolation for modem signal transmission
- Supports wet coupling configurations in telecommunication circuits
- Utilizes through-hole mounting for mechanical stability
Applications
- Telecom modem interface circuits
- Wet coupling signal transmission
- Audio and signal transformer applications
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status, as sources indicate non-compliance or detailed variations. Ensure the procurement matches the 600 Ohm impedance requirements and 75/95 Ohm DCR specifications. Confirm that the 1:1.41/1:1 isolation ratio aligns with the system design needs before finalizing orders.
Selection Notes
Select this component when a 600 Ohm to 600 Ohm impedance match is required for wet coupling scenarios. The specific DC resistance values of 75 Ohms and 95 Ohms must be compatible with the source and load impedances. Consider the through-hole package type if surface-mount alternatives are not suitable for the assembly process.
Part Context
This part belongs to the Tamura TTC series of audio and signal transformers. It is categorized under telecom transformers, specifically designed for modem applications.
