Current Sensors Procurement Notes

Verify the specific suffix code to confirm pin configuration and mounting style. Ensure the procurement source is an authorized LEM distributor to guarantee authenticity. Cross-reference the part number against official LEM documentation to avoid confusion with similar models in the LTC series that may have different current ratings or interface specifications.

Current Sensors Selection Notes

Select this model when a nominal current rating of 500 A is required with support for peak currents up to 1200 A. Consider the closed-loop architecture for applications demanding high accuracy and low thermal drift. Evaluate the physical footprint and PCB mounting requirements to ensure compatibility with the target assembly design before finalizing the component choice.

Current Sensors Part Context

This component belongs to the LTC series of current transducers from LEM. These sensors are designed for electronic measurement of various current types including DC, AC, and pulsed signals. The series emphasizes reliability and performance in demanding environments, serving as a critical interface for feedback control in power electronics.

Current Sensors Replacement Considerations

Direct substitutes within the same family include LTC 350-S/SP5 and LTC 500-S/SP6. Verify that alternative part numbers match the required nominal current and maximum peak current specifications.
