• Compact 0805 footprint suitable for space-constrained designs
• High impedance characteristic for effective noise suppression

Common Mode Chokes Applications

• Data line protection in portable electronic devices
• Noise filtering for high-speed signal interfaces
• EMI suppression in compact consumer electronics

Common Mode Chokes Procurement Notes

Verify availability status carefully as this component is officially listed as End-of-Life. Manufacturers typically discontinue such parts, making new production unlikely. Sourcing may only be possible through existing stock or secondary markets. Confirm lead times and authenticity if purchasing from non-direct suppliers. Plan for immediate design migration to avoid supply chain interruptions.

Common Mode Chokes Selection Notes

Consider alternative components within the same series or newer generations due to the discontinued status. Evaluate electrical parameters such as impedance and current rating against current design requirements. Ensure physical dimensions match existing PCB footprints if replacement is necessary. Review datasheets for updated specifications of successor models to guarantee compatibility.

Common Mode Chokes Part Context

This component belongs to the EXC series of common mode chokes designed for EMI/EMC applications. It is intended for use in circuits requiring noise suppression on differential lines. The 0805 size offers a balance between performance and board space efficiency. As a passive component, it does not require external power but affects signal integrity through its impedance characteristics.

Common Mode Chokes Replacement Considerations

Check Panasonic's official documentation for direct replacements or recommended alternatives. Verify that substitute parts meet identical impedance, current, and dimensional specifications. Ensure pinout compatibility if the package type differs. Consult distributor catalogs for currently available equivalents with similar performance profiles.
