HFB123049-300

Overview

The HFB123049-300 is a solid free-hanging ferrite core designed for cable and wiring applications. It provides an impedance of 258 Ohms at 300 MHz. The component features an inner diameter of 0.192 inches (4.88 mm) and an outer diameter of 0.485 inches (12.32 mm). Its length measures 1.000 inch (25.40 mm). Constructed from high-frequency material, it serves as a passive electromagnetic interference suppression element.

Feature Summary

• Solid construction for durable cable mounting
• High-frequency material composition for effective noise attenuation
• Free-hanging design facilitates easy installation on wires

Applications

• Cable and wiring EMI suppression
• Signal integrity enhancement in high-frequency circuits
• Passive noise filtering for electronic interconnects

Procurement Notes

Verify the specific impedance requirement of 258 Ohms at 300 MHz against your design specifications. Confirm that the physical dimensions, particularly the 4.88 mm inner diameter, accommodate the target cable gauge. Ensure the solid ferrite material aligns with the intended frequency range and environmental conditions of the application.

Selection Notes

Select this component when a robust, non-split ferrite core is required for cables that cannot be easily threaded through split cores. The fixed inner diameter dictates the maximum cable size. Consider the mechanical stability provided by the solid design versus the convenience of split-core alternatives for existing assemblies.

Part Context

This part belongs to the cable ferrites category from Laird-Signal Integrity Products. It is distinct from surface-mount components like common mode chokes or power inductors. The product is characterized by its physical geometry and magnetic material properties rather than electrical pin configurations.

Replacement Considerations

Direct substitutes must match the 258 Ohm impedance at 300 MHz and the 4.88 mm inner diameter. Verify that alternative solid ferrite cores maintain similar high-frequency performance characteristics and physical dimensions to ensure compatibility with existing cable assemblies.
