Procurement Notes

Verify that the specific part number matches the required 1:100 turn ratio and 40 A current rating for your design. Confirm that the physical dimensions fit within the allocated PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet for soldering profile recommendations to maintain component integrity during assembly.

Selection Notes

Select this component when precise current sensing with electrical isolation is required in compact designs. The 1:100 ratio suits applications where the sensing amplifier input impedance is compatible with the secondary output. Consider the 0.7 mOhm primary resistance for minimal insertion loss in high-current paths. Evaluate the thermal performance against the 130°C maximum limit under expected load conditions.

Part Context

This component belongs to TDK's current sense transformer portfolio, which focuses on providing reliable isolation and measurement capabilities for modern power electronics. These devices are integral to ensuring safety and efficiency in systems requiring real-time current feedback without direct electrical connection to the primary circuit.
