Current Sensors Procurement Notes
Verify the specific suffix SP1 against official LEM documentation to confirm pinout or mechanical variations compared to the standard CKSR 50-NP variant. Ensure the supplier provides valid RoHS compliance certificates and original manufacturer traceability records. Cross-reference the DigiKey part number 398-1098-ND for accurate component identification during sourcing.
Current Sensors Selection Notes
Select this component when precise bidirectional current sensing is required in compact modules. The 12.5mV/A sensitivity suits interfaces requiring moderate signal levels. Verify that the operating environment stays within the specified -40°C to 105°C range. Confirm that the 300kHz bandwidth meets the system's switching frequency requirements without signal degradation.
Current Sensors Part Context
This sensor belongs to the CKSR series from LEM USA Inc., specialized in flux gate current transducers. The series is designed for board-mount applications requiring high isolation and accuracy.
