HF28B2039

Overview

The HF28B2039 is a hinged snap-on ferrite clamp core manufactured by LeaderTech. It features a square shape with an internal diameter of 11.00 mm (0.433 inches). The external dimensions are 50.80 mm in length, 50.80 mm in width, and 43.20 mm in height. The component provides an impedance of 410 Ohms at a test frequency of 100 MHz. It is designed for cable bundle applications and utilizes material grade 28.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• High impedance characteristics provide effective electromagnetic interference suppression
• Square profile accommodates various cable bundle sizes within specified inner diameter limits

Applications

• Electromagnetic interference filtering on cable bundles
• Noise suppression in electronic equipment wiring
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific impedance value and physical dimensions against your system requirements before ordering. Confirm that the hinged mechanism is compatible with your assembly process. Ensure the material grade meets your environmental and thermal specifications. Cross-reference the manufacturer part number to avoid confusion with similar sleeve-style cores.

Selection Notes

Select this component when a non-invasive installation method is required for cable bundles. The 11 mm inner diameter must accommodate the total cross-section of the cables. Consider the 410 Ohm impedance at 100 MHz for high-frequency noise attenuation needs. The hinged design offers reusability compared to split-core alternatives.

Part Context

This ferrite core belongs to the LeaderTech EMI suppression product line. It is categorized under ferrite clamp-on cores. The product is intended for industrial and commercial electronic applications requiring reliable noise reduction. It complements other passive components in electromagnetic compatibility designs.

Replacement Considerations

Check for direct substitutes from LeaderTech with identical impedance and dimensional tolerances. Verify that alternative brands offer comparable material properties and hinged durability. Ensure any replacement maintains the same inner diameter clearance for the target cable bundle.
