Chip Ferrite Bead Procurement Notes

This component is officially obsolete and no longer manufactured by Samsung Electro-Mechanics. Verification of availability should focus on parametric equivalents or surplus stock. Confirm that substitute parts meet the original 6A rating and 30 Ohm impedance specifications. Check RoHS compliance status if required for specific regulatory environments.

Chip Ferrite Bead Selection Notes

Select this part for circuits requiring high current handling capability in a small footprint. The low DC resistance is critical for maintaining efficiency in power delivery networks. Ensure the application frequency aligns with the 100 MHz impedance specification. Verify thermal management capabilities given the 6A current rating and operating temperature range.

Chip Ferrite Bead Part Context

The CIS21P300NE belongs to Samsung's CIS series, which specializes in ferrite beads for high-current applications. This series is distinguished by its ability to handle currents up to 6A while maintaining a small physical size. It serves as a passive filter component for suppressing noise in power lines across various industrial and consumer electronics.

Chip Ferrite Bead Replacement Considerations
