HFB123049-100

Overview

The HFB123049-100 is a solid ferrite core manufactured by Laird-Signal Integrity Products, designed for cable and wiring applications. It provides an impedance of 97 ohms at 300 MHz. The component features a free-hanging mounting type with specific dimensional constraints: an inner diameter of 4.88 mm (0.192 inches), an outer diameter of 12.32 mm (0.485 inches), and a length of 10.00 mm (0.394 inches). This passive component serves as an electromagnetic interference filter for conductors passing through its central aperture.

Feature Summary

• Solid construction designed for wrapping around cables or wires
• Provides high-frequency noise attenuation with specified impedance characteristics
• Free-hanging form factor allows flexible installation on various wire gauges

Applications

• Cable EMI suppression in electronic assemblies
• Signal integrity enhancement for wiring harnesses
• RFI filtering for power and data lines

Procurement Notes

Verify the exact impedance frequency specification against the official datasheet, as some sources cite 300 MHz while others may reference different test conditions. Confirm that the solid core geometry matches the physical requirements of the target cable diameter. Ensure the material composition meets the necessary environmental and regulatory standards for the intended deployment environment.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable treatment rather than temporary testing. The 4.88 mm inner diameter dictates the maximum cable thickness it can accommodate. Consider the 97 ohm impedance value relative to the noise frequencies present in the application to ensure effective attenuation without excessive signal loss.

Part Context

This part belongs to the category of cable ferrites and wiring parts within Laird-Signal Integrity Products' portfolio. It is distinct from surface-mount chip beads like the HI series or LI series due to its through-hole/cable-wrapping form factor. The product is categorized under passive components used for electromagnetic compatibility and signal integrity management in complex electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must consult manufacturer catalogs for equivalent impedance and dimensional specifications.
