EMI1806R-105

Chip Ferrite Bead Overview

The Delevan EMI1806R-105 is a surface-mount ferrite chip bead designed for EMI and RFI suppression. It features an impedance of 105 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 200 mOhms. Housed in a 1806 (4516 metric) package measuring 3.2 mm x 2.5 mm x 1.3 mm, it operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference and radio frequency interference suppression through high impedance characteristics.

Chip Ferrite Bead Applications

• Signal line filtering in electronic circuits
• Power supply noise reduction
• High-frequency circuit protection

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status directly from the official datasheet, as availability varies by source. Ensure the ordering suffix matches the required reel quantity if applicable. Cross-reference the part number alias EMI1806R-105 T2000 for packaging details.

Chip Ferrite Bead Selection Notes

Select this component when a 105 Ohm impedance at 100 MHz is required for noise suppression. The 300 mA current rating suits low-power signal lines. The 1806 SMD package allows for compact PCB layouts. Verify that the 200 mOhm DCR meets the voltage drop requirements of the target circuit application.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the EMI1806R series from Delevan. It is categorized under passive components and specifically ferrites. The product is distinct from power inductors like the PD105R series or variable inductors like the 9406R series, serving primarily as a suppressor rather than an energy storage element.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify pin compatibility and impedance curves when considering alternative manufacturers.
