Chip Ferrite Bead Applications

• EMI/RFI suppression circuits

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation as API Delevan or Delevan during sourcing. Confirm the specific suffix requirements if ordering from distributors, such as T2000 variants. Ensure the component meets RoHS compliance standards required for the target assembly. Cross-reference the Mouser part number 807-EMI1806R-80 for accurate catalog identification. Validate that the 1806 package footprint matches the PCB design constraints.

Chip Ferrite Bead Selection Notes

Select this component when an 80 Ohm impedance at 100 MHz is required for noise filtering. The 400 mA current rating suits applications with moderate DC bias. The 1806 SMD package allows for compact board layouts. Consider the 100 mOhm DC resistance impact on signal integrity. Verify thermal performance within the -55°C to +125°C operating range.
