WBC2.5/A-4S2

Overview

The Ferroxcube WBC2.5/A-4S2 is a wideband RF choke designed for EMI suppression applications. It features an axial leaded construction with a ferrite bead made from 4S2 material. The component measures 10 mm in length and 6 mm in diameter. It provides an impedance of 400 Ohms at 10 MHz, serving as a power line ferrite bead to attenuate high-frequency noise.

Feature Summary

• Axial leaded design for through-hole mounting
• Wideband frequency response characteristics
• Constructed with 4S2 ferrite material

Applications

• EMI suppression circuits
• Power line filtering
• RFI attenuation

Procurement Notes

Verify the specific suffix '4S2' to confirm the magnetic material composition, as this determines the impedance profile. Ensure the axial package dimensions match the PCB layout requirements. Confirm RoHS compliance status with the supplier prior to ordering, as manufacturing standards may vary by production batch.

Selection Notes

Select this component when broad-spectrum noise reduction is required rather than narrow-band filtering. The 4S2 material offers specific permeability characteristics suitable for general-purpose EMI suppression. Evaluate the physical size constraints against the 10mm length and 6mm diameter specifications before integration into the assembly.

Part Context

This part belongs to the WBC series of wideband chokes manufactured by Ferroxcube. These components are engineered for signal integrity preservation while suppressing electromagnetic interference across a wide frequency range. The axial form factor allows for simple insertion into standard electronic assemblies without requiring specialized surface-mount equipment.

Replacement Considerations

Substitutes must match the 4S2 material grade and axial dimensions. Verify that alternative parts provide comparable impedance characteristics at 10 MHz to ensure equivalent noise suppression performance in the target application circuit.
