HI28B2039

Overview

The HI28B2039 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features a square shape with an inner diameter of 11.00 mm (0.433 inches) and an outer dimension of 50.80 mm x 17.01 mm. The component utilizes material grade 28, providing an impedance of 410 Ohms at 100 MHz. Designed for cable bundle applications, it offers high impedance grip and variable diameter end ports to accommodate various cable sizes.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables without disconnection
• High impedance characteristics effective for suppressing electromagnetic interference in telecommunications
• Variable diameter end ports provide flexibility for securing cables of different thicknesses

Applications

• Telecommunications switching equipment
• Cable bundle noise suppression
• Electronic enclosure interconnect shielding

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Leader Tech datasheet before integration. Confirm that the hinged mechanism meets the mechanical retention requirements of the target assembly. Ensure compatibility with the cable outer diameter range supported by the variable port design.

Selection Notes

Select this component when a non-intrusive EMI solution is required for pre-assembled cables. The snap-on style eliminates the need to thread cables through solid cores. Consider the 410 Ohm impedance rating at 100 MHz to ensure adequate attenuation for the specific noise frequencies present in the application environment.

Part Context

Leader Tech Inc. specializes in EMI shielding products for circuit boards and enclosures. This ferrite core belongs to their sleeve snap series, designed for high-impedance noise suppression.
