AB4X2X8W

Overview

The AB4X2X8W is a solid round ferrite core manufactured by Toshiba Semiconductor and Storage. It features an inner diameter of 1.50 mm (0.059 inches) and an outer diameter of 5.00 mm (0.197 inches). The component has a fixed length of 9.50 mm (0.374 inches). Designed for free-hanging mounting, this passive electromagnetic interference suppression device is constructed from solid ferrite material to provide noise filtering on cables.

Feature Summary

• Solid construction provides consistent magnetic properties without air gaps
• Free-hanging design allows easy installation onto existing cable assemblies
• Round geometry supports uniform magnetic flux distribution around the conductor

Applications

• Electromagnetic interference suppression on signal cables
• Noise filtering in consumer electronic wiring harnesses
• Common mode choke applications for data transmission lines

Procurement Notes

Verify the specific ferrite material composition and impedance characteristics required for your frequency range, as datasheets may vary by production batch. Confirm that the 1.50 mm inner diameter accommodates your target cable gauge with appropriate clearance. Ensure the solid design meets your mechanical space constraints compared to split-core alternatives.

Selection Notes

Select this component when a permanent, non-split ferrite solution is required for cables fitting within the 1.50 mm bore. Consider the fixed dimensions of 5.00 mm outer diameter and 9.50 mm length for enclosure or routing planning. Evaluate if the solid construction offers sufficient durability for the intended mechanical environment compared to snap-on variants.

Part Context

This part belongs to Toshiba's cable ferrite series, designed for passive EMI mitigation. Unlike integrated circuits, these are passive magnetic components used to suppress high-frequency noise on wires. The AB4X2X8W represents a standard size option within their portfolio of solid ferrite cores for general-purpose electronics applications.

Replacement Considerations

Direct substitutes must match the 1.50 mm ID, 5.00 mm OD, and 9.50 mm length. Verify equivalent material permeability and impedance curves at target frequencies. Split-core alternatives require different installation methods but offer similar electrical performance if dimensions align.
