TCS-08

Overview

The TCS-08 is a surface-mount current sense transformer manufactured by Tamura Corporation. It features a primary-to-secondary turns ratio of 1:125 and supports a minimum operating frequency of 250kHz. The device has a low primary resistance of 6mOhm and a secondary resistance of 7.7Ohm, with an inductance of 3mH. Designed for board mounting, it accommodates a rated current of 6A and measures 7.00mm in length by 6.30mm in width.

Feature Summary

• Provides galvanic isolation between primary and secondary circuits via magnetic coupling
• Utilizes surface mount technology for automated assembly integration
• Features鸥翼型 (gull-wing) terminal configuration for secure PCB connection

Applications

• Current sensing in switching power supplies
• Overcurrent protection circuits
• Feedback control loops in DC-DC converters

Procurement Notes

Verify the specific manufacturer part number against official Tamura documentation to ensure compatibility with design requirements. Confirm that the 1:125 turns ratio and 250kHz minimum frequency meet system specifications. Check for any required ordering suffixes or variations that may affect performance characteristics before finalizing procurement.

Selection Notes

Select this component when a compact, surface-mount solution for high-frequency current sensing is required. Ensure the 6A rated current aligns with the maximum expected load. Verify that the 7.00mm x 6.30mm footprint fits within the available PCB area. Consider the 3mH inductance value for circuit stability at the target operating frequency.

Part Context

The TCS-08 belongs to Tamura's line of current sense transformers, designed for applications requiring precise current monitoring with electrical isolation. It serves as a passive component in power electronics, converting primary current into a proportional secondary voltage for measurement or control purposes without direct electrical contact.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult Tamura technical support for potential alternatives if this specific model is discontinued or unavailable.
