Overview
The Tamura TTC-511 is a surface-mount telecommunications transformer designed for voice and modem line applications. It features a primary impedance of 600 Ohms and a secondary impedance of 287 Ohms, providing an impedance ratio of 600:287. The component is constructed for SMD mounting and is RoHS compliant, ensuring lead-free status. It is engineered to facilitate maximum power transfer during impedance matching operations within telecommunication circuits.
Feature Summary
- Designed specifically for voice and modem line transformer applications
- Optimized for maximum power transfer during impedance matching operations
- Surface mount device (SMD) construction for automated assembly
Applications
- Encapsulated modem circuits
- Voice communication line interfaces
- Telecommunications signal processing equipment
Procurement Notes
Verify the specific impedance configuration against design requirements, as the TTC series includes variants with different secondary impedances such as 346 Ohms or 510 Ohms. Confirm that the 600:287 Ohm specification matches the target circuit topology. Ensure the surface-mount package type aligns with the PCB footprint specifications before finalizing procurement orders.
Selection Notes
Select the TTC-511 when a 600:287 Ohm impedance transformation is required for SMD-based telecommunication designs. This model is suitable for applications demanding high-quality design characteristics for efficient power transfer. Consider alternative models like the TTC-512 if a 600:510 Ohm ratio is necessary instead of the 287 Ohm secondary winding.
Part Context
The TTC-511 belongs to Tamura's TTC series of high-quality telecommunications transformers. This series is recognized for its ability to achieve maximum power transfer during impedance matching operations. The components are widely used in the telecommunications industry for voice and data line applications, offering reliable performance in compact surface-mount formats.
Replacement Considerations
The TTC-512 is a related model within the same series but features a 600:510 Ohm impedance ratio instead of 600:287 Ohms. Other models in the series include the TTC-511 and TTC-512, which share similar construction standards but differ in electrical specifications. Verify impedance compatibility before substituting.
