Common Mode Chokes Procurement Notes

Verify the specific manufacturing origin, as production has been transferred from Singapore/Batam to Jiangmen, China. Confirm RoHS compliance status directly with the supplier or official documentation, as availability may vary by region. Check for end-of-life notices or alternative part recommendations if long-term supply stability is required.

Common Mode Chokes Selection Notes

Select this component when a 1.1A current rating and compact SMD form factor are required for high-density PCB layouts. Ensure the operating temperature range of -55°C to 125°C meets the environmental requirements of the target application. Verify that the 308mΩ DC resistance aligns with the power loss constraints of the circuit design.

Common Mode Chokes Part Context

This component belongs to the ELF-17N series of high-performance line filters. It utilizes a powdered iron core for low loss operation up to 3MHz. The series is engineered for surface mount technology, supporting both flow and reflow soldering processes suitable for automated assembly lines.

Common Mode Chokes Replacement Considerations

Consult official Panasonic documentation for confirmed substitute part numbers within the ELF-xxn series. Verify pin compatibility and electrical specifications before substituting.
