Overview
The Delevan 4211R-27 is an axial leaded ferrite bead designed for EMI suppression. It exhibits an impedance of 162 Ohms at a test frequency of 25 MHz with a tolerance of 0.025%. The component features a 1-line configuration and utilizes axial termination for through-hole mounting. Physical dimensions include a diameter of 3.51 mm and a length of 0.375 inches.
Feature Summary
- Provides high-impedance attenuation for electromagnetic interference in the specified frequency range
- Utilizes axial leaded construction for reliable through-hole printed circuit board integration
- Offers tight manufacturing tolerance to ensure consistent filtering performance across production batches
Applications
- Electromagnetic interference suppression in electronic circuits
- Radio frequency interference filtering applications
- Signal integrity enhancement in axial leaded assemblies
Procurement Notes
Verify component authenticity by checking manufacturer markings against official API Delevan specifications. Confirm the specific suffix matches the required impedance value, as variations exist within the series. Ensure compatibility with existing through-hole assembly processes. Review datasheets for handling precautions related to axial leads. Validate that the obsolete status does not impact long-term supply requirements.
Selection Notes
Select this component when axial mounting is required for EMI filtering at 25 MHz. Compare impedance characteristics against alternative ferrite beads to ensure adequate noise attenuation. Verify physical space constraints match the 3.51 mm diameter and 0.375 inch length. Consider the tight tolerance requirement if precise filtering behavior is critical for the design.
Part Context
This part belongs to the 4211 series of ferrite beads manufactured by API Delevan. The series includes various impedance values tailored for different frequency suppression needs. These components are generally classified as passive filters used to dampen high-frequency noise on signal lines.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer cross-reference tools for potential alternatives.
