Current Sensors Procurement Notes
Verify the specific suffix SP11 against the manufacturer's official documentation to confirm pinout and packaging details. Note that this component may be classified as 'Not For New Designs' in some distributor catalogs; consult LEM USA Inc. directly for current availability and lifecycle status before finalizing procurement plans.
Current Sensors Selection Notes
Select this transducer when precise measurement of currents up to 300 A is required with fast dynamic response. Ensure the application environment supports the specified 12 V to 20 V supply voltage. Consider the closed-loop architecture for applications demanding high linearity and low temperature drift compared to open-loop alternatives.
Current Sensors Part Context
This part belongs to LEM's standard series of current transducers. It utilizes Hall effect principles combined with closed-loop compensation to achieve accurate current replication. The SP11 designation typically refers to a specific connector or mounting configuration within the LF 305 product family.
Current Sensors Replacement Considerations
