Procurement Notes

Verify the specific datasheet version for the 55651 part number to confirm electrical tolerances and thermal characteristics before finalizing design specifications. Ensure that the selected supplier provides documentation confirming RoHS compliance status and moisture sensitivity level (MSL) ratings. Cross-reference the manufacturer's ordering suffixes to guarantee the correct package variant is procured, as minor packaging differences may exist between distributors.

Selection Notes

Select this component when a through-hole current transformer is required for frequencies between 10 kHz and 300 kHz. Consider the 470 Ohm impedance and 24 mH inductance values to ensure compatibility with the target circuit's signal processing requirements. Evaluate the board-mount form factor against available PCB space constraints and verify that the manufacturing process supports the specified humidity sensitivity handling procedures during assembly.

Part Context

This current transformer is part of Bourns' 556xx series, which focuses on board-mount solutions for magnetic components.
