WBC2.5/R-3S4-Z

Overview

The WBC2.5/R-3S4-Z is an axial ferrite bead from the Ferroxcube WBC2.5/R series, utilizing Material 3S4 for EMI suppression. It exhibits a minimum impedance magnitude of 600 Ohms at 50 MHz and 700 Ohms at frequencies greater than or equal to 1 MHz. The component features a cylindrical body with a diameter of 6 mm and a length of 10 mm. Designed as a wideband choke, it provides high attenuation in the radio frequency range while maintaining low DC resistance characteristics suitable for signal and power line filtering applications.

Feature Summary

• High impedance performance across wide frequency bands using specialized ferrite material
• Axial lead configuration designed for through-hole mounting on printed circuit boards
• Compact cylindrical geometry optimized for space-constrained electronic assemblies

Applications

• EMI suppression in power supply circuits
• Signal filtering in battery chargers
• Noise reduction in portable electronic devices
• Wideband choking in energy-efficient systems

Procurement Notes

Verify the specific ordering suffix and material grade against the manufacturer's current datasheet to ensure compliance with project requirements. Confirm that the axial package dimensions match the PCB footprint design. Check for RoHS compliance status and country of origin details required by regulatory standards. Ensure the selected variant matches the intended impedance profile for the target frequency range.

Selection Notes

Select this component when high attenuation is required at frequencies above 1 MHz. The 3S4 material offers a balance of permeability and resistivity suitable for general EMI suppression. Consider the axial form factor for manual assembly or automated insertion processes. Evaluate the physical size constraints against the available board space. Compare impedance curves with alternative materials if specific frequency targeting is critical.

Part Context

This part belongs to the WBC2.5 series of wideband chokes manufactured by Ferroxcube. The series includes various material grades such as 4B1 and configurations like radial bend variants. The WBC2.5/R designation indicates the axial style within this product family. These components are engineered for effective noise suppression in modern electronic equipment requiring reliable EMI control.

Replacement Considerations

Cross-reference with other axial ferrite beads offering similar impedance values at 50 MHz. Verify mechanical compatibility including lead spacing and body diameter. Ensure the substitute material provides equivalent high-frequency loss characteristics. Check for availability of equivalent parts from other manufacturers if supply chain diversification is needed.
