Overview
The Delevan 4211R-1 is a ferrite bead component designed for EMI and RFI suppression in electronic circuits. It features an axial leaded package suitable for through-hole mounting applications. The device provides an impedance of 750 Ohms at a test frequency of 100 MHz. It is classified as a single-line filter bead with standard termination types.
Feature Summary
- Provides effective electromagnetic interference (EMI) and radio frequency interference (RFI) suppression
- Utilizes axial leaded construction for reliable through-hole PCB integration
- Engineered for high-frequency noise attenuation in signal lines
Applications
- Signal line filtering in communication equipment
- Noise suppression in consumer electronics power and data lines
- EMI mitigation in industrial control systems
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with API Delevan or authorized distributors before procurement. Confirm that the axial package dimensions match the target PCB footprint requirements. Ensure the 750 Ohm impedance characteristic aligns with the circuit's noise spectrum needs. Check for any specific handling instructions regarding leaded components in the official documentation.
Selection Notes
Select this component when axial mounting is required for ferrite bead suppression. The 750 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Consider the physical size constraints of the axial package relative to available board space. Evaluate if the single-line configuration meets the circuit's filtering topology without requiring additional components.
Part Context
This part belongs to the 4211R series of ferrite beads manufactured by API Delevan. The series focuses on providing passive filtering solutions for EMI/RFI issues. These components are distinct from surface-mount variants and offer traditional through-hole connectivity options for legacy or robust design requirements.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts maintain the 750 Ohm @ 100 MHz impedance specification. Verify that alternative axial ferrite beads fit the existing mechanical envelope and thermal characteristics.
