TCS-03

Overview

The Tamura TCS-03 is a current sense transformer designed for invasive current measurement applications. It features a 1:40 turns ratio and operates with a primary current rating of 6A. The component utilizes a gull wing termination style for surface mount installation on printed circuit boards. Its physical dimensions are specified as 7.00mm in length, 8.40mm in width, and a maximum seated height of 5.20mm. The device incorporates an inductance value of 320 µH to support signal integrity in power monitoring circuits.

Feature Summary

Provides invasive current sensing capabilities via a dedicated transformer architecture
Supports surface mount integration using gull wing termination configuration
Delivers precise current transformation through a fixed 1:40 turns ratio

Applications

Power supply current monitoring systems
Invasive current measurement in electronic circuits
Signal conditioning for power management units

Procurement Notes

Verify the specific manufacturer datasheet for complete electrical characteristics and thermal limits before integration. Confirm that the surface mount footprint matches the target PCB design requirements. Ensure the invasive nature of the sensor aligns with the system's safety and isolation standards. Cross-reference the 1:40 ratio against the intended primary current range to prevent saturation.

Selection Notes

Select this component when invasive current sensing is required within a compact surface mount form factor. The 1:40 ratio suits applications where the primary current remains within the 6A rating. Consider the 320 µH inductance for frequency response needs. Evaluate the 7.00mm x 8.40mm package size against available board space constraints.

Part Context

The TCS-03 belongs to Tamura’s TCS series of current sense transformers. This series focuses on providing reliable current monitoring solutions for power electronics. The component represents a specialized passive element used for feedback and protection in power conversion topologies.
