Procurement Notes

Verify component availability carefully as this part number is officially listed as obsolete and no longer manufactured by Murata Power Solutions. Confirm that any available stock represents genuine inventory rather than surplus or refurbished units. Ensure that sourcing channels provide valid traceability documentation. Review datasheets from authorized distributors to confirm the specific manufacturing lot details before finalizing procurement decisions.

Selection Notes

Select this component only if the design specifically requires a 1:1:200 turns ratio and a 15 A primary current rating. Verify that the PCB layout accommodates the required surface-mount footprint dimensions. Ensure the operating environment remains within the specified frequency range of 50 kHz to 500 kHz. Consider that the part is obsolete; alternative solutions must be evaluated for equivalent electrical performance and physical compatibility.

Part Context

The 55200C belongs to the Current Sense Transformers category from Murata Power Solutions. It is designed for compact, high-accuracy AC current sensing in electronic circuits.
