Current Sense Transformers Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and thermal characteristics before integration. Confirm that the 45 A primary current rating aligns with the peak load requirements of the target circuit. Ensure the operating frequency remains within the 47 Hz to 400 Hz specification to maintain accurate signal transformation and prevent saturation.

Current Sense Transformers Selection Notes

Select this component when galvanic isolation is required for current monitoring in low-frequency AC environments. The 1:2500 ratio suits applications needing significant signal attenuation for safe measurement. Consider the through-hole package for robust mechanical attachment in industrial settings where vibration resistance is critical compared to surface-mount alternatives.

Current Sense Transformers Part Context

This part belongs to Würth Elektronik's current sense transformer portfolio, which focuses on providing isolated feedback solutions for power electronics. These components are engineered to replace resistive shunts in applications where isolation voltage ratings and reduced power loss are necessary design constraints.

Current Sense Transformers Replacement Considerations

Cross-reference with other Wurth Elektronik current sense transformers offering similar 1:2500 ratios and 45 A ratings. Verify that substitute parts match the 47-400 Hz frequency range and through-hole footprint dimensions to ensure mechanical and electrical compatibility without redesigning the PCB layout.
