4212R-1

Overview

The Delevan 4212R-1 is a single-line ferrite bead designed for EMI/RFI suppression in axial through-hole configurations. It exhibits an impedance of 750 Ohms at a test frequency of 100 MHz. The component measures 10.5 mm in length and 6.35 mm in diameter, featuring wound bead construction with one turn. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression at specified frequencies
• Utilizes axial leaded construction for reliable through-hole PCB mounting
• Constructed with wound bead technology to ensure stable performance across wide temperature variations

Applications

• High-frequency noise filtering in signal lines
• EMI suppression in power distribution circuits
• RFI mitigation in communication equipment interfaces

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm impedance values and physical dimensions. Ensure compatibility with existing board layouts regarding axial lead spacing and hole diameters. Confirm RoHS3 compliance status if required by project specifications. Cross-reference datasheet revision dates to validate parameter accuracy before integration into production designs.

Selection Notes

Select this component when axial mounting is preferred over surface mount alternatives. Consider the 750 Ohm impedance rating relative to target noise frequencies. Evaluate thermal management requirements given the operating temperature limits. Compare physical footprint constraints against available PCB real estate for through-hole implementation.

Part Context

This part belongs to the Delevan 4212R series of ferrite beads. The series offers various impedance options tailored for different suppression needs. Components in this family share similar mechanical characteristics but differ in electrical performance parameters defined by their specific model numbers.

Replacement Considerations

Direct substitutes include other Delevan axial ferrite beads with matching 750 Ohm impedance at 100 MHz. Verify equivalent current ratings and physical dimensions before substitution. Consult manufacturer cross-reference lists for approved alternative part numbers.
