Common Mode Chokes Procurement Notes

Verify the specific suffix 'W' against official Panasonic documentation to confirm lead-free status and RoHS compliance. Ensure the 1.4A current rating and 10mH inductance match the target circuit requirements. Cross-reference the DCR value of 274 mOhm with system loss calculations. Confirm the through-hole package dimensions fit the mechanical layout before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 10 mH inductance at 1.4 A is required for common mode interference suppression. The through-hole format suits applications where mechanical stability is prioritized over surface area constraints. Verify that the operating temperature range of -20°C to 105°C aligns with the environmental conditions of the end-use device.

Common Mode Chokes Part Context

This part belongs to the ELF series of common mode chokes from Panasonic Electronic Components. The series offers various inductance and current combinations for different filtering needs. The ELF-18D650W specifically targets applications requiring moderate inductance values with standard through-hole assembly methods.

Common Mode Chokes Replacement Considerations

Consult official Panasonic documentation for direct substitutes. Generic equivalents may differ in core material or saturation characteristics. Verify pin compatibility and thermal performance before substitution.
