HA28B2039

Overview

The HA28B2039 is a hinged ferrite cable core manufactured by Leader Tech Inc., designed for electromagnetic interference (EMI) suppression. It features a solid construction with an impedance of 410 Ohms at the specified test frequency. The component has an internal diameter of 12.70 mm, allowing it to accommodate cables of this specific size. External dimensions include a length of approximately 45.7 mm, width of 45.2 mm, and height of 43.2 mm. It is supplied in bulk packaging.

Feature Summary

• Hinged design allows for easy installation around existing cables without disconnection
• Solid ferrite material provides effective EMI/RFI noise suppression
• Adhesive base option available for secure mounting applications

Applications

• Suppression of electromagnetic interference on single cables up to 12.70 mm diameter
• Noise reduction in electronic equipment interconnects
• EMI shielding for data and signal lines in industrial environments

Procurement Notes

Verify the exact impedance value and test frequency from the official Leader Tech datasheet before procurement. Confirm whether the part includes an adhesive base or requires separate mounting hardware. Check RoHS compliance status and ensure the internal diameter matches the target cable bundle size precisely to avoid fitment issues.

Selection Notes

Select this component when a hinged ferrite core is required for cables with a 12.70 mm inner diameter. The 410 Ohm impedance indicates suitability for higher frequency noise suppression compared to lower impedance cores. Ensure the external dimensions fit within the available space constraints of the enclosure or application area.

Part Context

Leader Tech Inc. specializes in EMI shielding solutions for circuit boards, enclosures, and cables. The HA28B2039 belongs to their range of ferrite cable cores, which are passive components used to suppress high-frequency noise. These products are commonly used in industries requiring robust electromagnetic compatibility.

Replacement Considerations

Check for compatible hinged ferrite cores with similar internal diameters and impedance characteristics. Verify that any substitute part maintains the same external dimensions and mounting style if space or attachment methods are constrained.
