HF28B2038

Overview

The HF28B2038 is a square, hinged ferrite clamp-on core manufactured by LeaderTech Inc. It features a material grade of 410 and provides high impedance for EMI suppression. The component has an inner diameter of 10.9 mm (0.428 inches) to accommodate cable bundles. External dimensions are 45.7 mm in length, 45.2 mm in width, and 43.2 mm in height. It utilizes a button-style base for mounting.

Feature Summary

• Hinged design allows installation around existing cables without disconnection
• High impedance characteristics for effective electromagnetic interference suppression
• Square cross-section geometry optimized for cable bundle applications

Applications

• Suppression of common mode noise on cable bundles
• EMI filtering for electronic equipment cabling
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific mounting configuration required for your application. Confirm that the inner diameter accommodates the target cable bundle diameter with appropriate clearance. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the button base style aligns with your assembly constraints.

Selection Notes

Select this part when a snap-on solution is preferred over split cores for ease of retrofitting. The 410 material grade offers balanced performance for general EMI suppression. Consider the external dimensions to ensure sufficient space within the enclosure. Verify compatibility with the cable types intended for noise reduction.

Part Context

This component belongs to the LeaderTech ferrite clamp-on core series designed for EMI/RFI mitigation. It falls under the category of passive components used for signal integrity management. The product line includes various shapes and materials tailored for different frequency ranges and cable sizes.

Replacement Considerations

Cross-reference with other 410 material hinged ferrites from different manufacturers if supply constraints exist. Ensure equivalent impedance values and physical dimensions match the original design requirements before substitution.
