WBC1.5/A-4B1-Z

Overview

The Ferroxcube WBC1.5/A-4B1-Z is an axial ferrite bead designed for electromagnetic interference suppression in electronic circuits. It utilizes the proprietary 4B1 ferrite material, which provides high impedance characteristics across a broad frequency spectrum. The component exhibits an impedance of 350 Ohms at a test frequency of 250 MHz. Its physical construction features an axial leaded package, facilitating through-hole mounting on printed circuit boards. This configuration allows for effective integration into wiring harnesses and signal lines where common-mode noise reduction is required.

Feature Summary

• Utilizes 4B1 ferrite material for wideband noise attenuation
• Axial leaded package design for secure through-hole PCB mounting
• High impedance performance at 250 MHz for effective EMI suppression

Applications

• Signal line filtering in consumer electronics
• Power supply input/output noise suppression
• Data bus protection against electromagnetic interference

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Ferroxcube datasheet before finalizing procurement decisions. Ensure that the axial lead spacing matches the target printed circuit board layout requirements. Confirm that the 4B1 material grade aligns with the intended operating temperature range and frequency spectrum of the application to guarantee optimal noise suppression performance.

Selection Notes

Select this component when axial mounting is preferred over surface mount alternatives for mechanical stability. The 4B1 material offers a balanced trade-off between impedance magnitude and saturation current capabilities. Consider the physical dimensions of the bead relative to available board space and ensure that the lead wire gauge supports the expected current load without excessive voltage drop or thermal issues during operation.

Part Context

This part belongs to the WBC1.5/A series of axial ferrite beads manufactured by Ferroxcube. The series is characterized by its use of specific ferrite formulations tailored for broadband noise suppression. The '4B1' designation indicates the specific magnetic material composition, while the 'WBC1.5' prefix denotes the physical size and form factor within the manufacturer's product lineup.

Replacement Considerations

Direct substitutes include other axial ferrite beads from Ferroxcube using similar 4B1 material, such as variants with different impedance ratings. Cross-brand replacements require matching the axial footprint, lead spacing, and impedance profile at the critical operating frequency to maintain circuit integrity.
