Common Mode Chokes Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the through-hole package style matches your PCB layout requirements. Ensure the 1.7A current rating meets the operational demands of the target circuit. Cross-reference the 250mOhm DCR specification against thermal management constraints. Validate compliance with relevant safety standards for AC line components before final integration.

Common Mode Chokes Selection Notes

Select this component when hybrid filtering is required for AC lines within a through-hole design constraint. The 1.7A rating defines the maximum continuous current capacity. Consider the physical dimensions of the through-hole package during board layout planning. Evaluate the trade-off between the 1.1mH common mode inductance and the 65uH differential inductance for specific noise profiles. Ensure the operating environment aligns with the component's rated specifications.

Common Mode Chokes Part Context

This part falls under the broader category of EMI suppression filters manufactured by Murata Electronics. It is classified specifically as a common mode choke or hybrid choke coil. The product serves as a passive component for managing electromagnetic interference in electrical circuits. It is distinct from surface mount alternatives due to its through-hole termination style.

Common Mode Chokes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the 1.7A current rating, 250mOhm DCR, and through-hole package dimensions. Consult official Murata resources for potential alternative models if this specific part number is discontinued.
