WBC2.5/SP-4B1-Z

Overview

The Ferroxcube WBC2.5/SP-4B1-Z is a ferrite bead designed for electromagnetic interference suppression in through-hole applications. It features an axial package with radial bends, measuring 6 mm in diameter and 10 mm in length. The component utilizes material grade 4B1 to provide high impedance characteristics. Key electrical specifications include an impedance of 700 Ohms at 75 MHz. It supports one line of signal path filtering.

Feature Summary

• Provides effective common-mode noise attenuation for single-line circuits
• Utilizes specialized ferrite material for targeted frequency suppression
• Designed for robust mechanical mounting via through-hole technology

Applications

• Power supply input filtering
• Signal line noise suppression
• Electromagnetic compatibility enhancement in electronic assemblies

Procurement Notes

Verify the specific suffix Z against official Ferroxcube documentation to confirm any special handling or packaging requirements distinct from the standard WBC2.5/SP-4B1 variant. Ensure the axial-radial bend form factor matches the PCB layout constraints. Cross-reference the material grade 4B1 impedance curve with the target operating frequency to validate performance suitability for the specific EMI profile.

Selection Notes

Select this component when a through-hole ferrite bead with radial leads is required for space-constrained axial mounting positions. The 4B1 material offers a specific impedance profile suitable for mid-frequency noise reduction. Consider the physical dimensions of 6x10 mm to ensure adequate clearance on the printed circuit board. Validate that the single-line configuration aligns with the circuit topology requiring common-mode or differential-mode suppression.

Part Context

This part belongs to the WBC2.5 series of ferrite beads manufactured by Ferroxcube. The series typically includes various material grades and physical configurations to address different electromagnetic interference challenges. The SP designation indicates a specific lead configuration within the product family, distinguishing it from straight axial or other bent variants.

Replacement Considerations

Direct substitutes may include the WBC2.5/A-4B1, which shares similar material properties but differs in lead configuration. Verify impedance curves and physical dimensions before substitution. Other series members like WBC3/R-4S2 offer different performance characteristics and should be evaluated based on specific circuit requirements rather than assumed interchangeability.
