Overview
The Delevan 4211R-2 is a surface-mount ferrite bead designed for EMI and RFI suppression in electronic circuits. It features an impedance of 50 Ohms at 100 MHz, with a maximum DC current rating of 860 mA and a maximum DC resistance of 170 milliohms. The component measures 3.94 mm in length, 3.18 mm in width, and 2.03 mm in height. It operates within a temperature range of -55°C to +125°C and utilizes standard SMD/SMT termination types.
Feature Summary
- Provides effective electromagnetic interference and radio frequency interference suppression through high-frequency impedance characteristics.
Applications
- High-speed digital signal line filtering
- Power supply noise reduction
- EMI suppression in compact electronic modules
Procurement Notes
Verify the specific impedance value and current ratings against the official datasheet before integration. Confirm that the surface-mount package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number to avoid confusion with similar axial or through-hole variants.
Selection Notes
Select this component when surface-mount implementation is required for EMI filtering. Consider the 50 Ohm impedance at 100 MHz for target noise frequencies. Evaluate the 860 mA current limit to ensure it supports your circuit's operational load without saturation. Compare physical dimensions against available board space constraints.
Part Context
This component belongs to the Delevan ferrite bead series, which offers various configurations for noise suppression. The 4211R-2 specifically addresses surface-mount applications, distinguishing it from axial leaded alternatives like the 4212R-1. It serves as a passive filter element within broader electronic systems requiring signal integrity maintenance.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads by matching impedance curves, current ratings, and physical package dimensions.
