TCS-05

Overview

The Tamura TCS-05 is a surface-mount current sense transformer designed for AC current measurement applications. It features a fixed 1:60 turns ratio and supports a minimum operating frequency of 250kHz. The device specifies a primary resistance of 6mOhm, a secondary resistance of 1.75Ohm, and an inductance of 720µH. Its compact physical dimensions are 7.00mm in length, 8.40mm in width, and a maximum seated height of 5.20mm.

Feature Summary

• Provides galvanic isolation between the high-current primary circuit and the low-voltage sensing circuitry
• Designed specifically for invasive AC current measurement with a precise 1:60 transformation ratio
• Optimized for high-frequency operation starting at 250kHz to ensure accurate signal fidelity

Applications

• AC current measurement in power supply circuits
• Current sensing in high-frequency switching applications
• Invasive monitoring systems requiring electrical isolation

Procurement Notes

Verify that the specific order matches the TCS-05 designation to confirm the 1:60 ratio and 250kHz minimum frequency requirements. Ensure the application design accommodates the specified 6mOhm primary and 1.75Ohm secondary resistances. Confirm that the PCB layout supports the 7.00mm x 8.40mm surface-mount footprint and the 5.20mm maximum height constraint for proper assembly clearance.

Selection Notes

Select this component when invasive AC current sensing with galvanic isolation is required at frequencies above 250kHz. The 1:60 ratio suits applications needing significant signal attenuation from the primary side. Consider the 720µH inductance value for impedance matching in the sensing circuit. This surface-mount package is suitable for automated assembly processes where space efficiency is critical.

Part Context

The TCS-05 belongs to Tamura's line of current sense transformers, which are engineered for precision measurement in electronic systems. These components utilize magnetic coupling to transfer current information while maintaining electrical separation. The series is characterized by stable performance across defined frequency ranges and robust construction for reliable operation in demanding environments.
