28B1225-0

Overview

The Leader Tech Inc. 28B1225-0 is a solid ferrite core designed for cable electromagnetic interference suppression. It features a circular geometry with an internal diameter of 19.10 mm and an external diameter of 31.10 mm. The component has a length of 15.50 mm and provides an impedance of 97 Ohms at 100 MHz. Constructed from specific ferrite material, it serves as a passive filter element for high-frequency noise reduction on cables passing through its central aperture.

Feature Summary

• Solid cylindrical ferrite construction for secure cable mounting
• Provides 97 Ohms impedance at 100 MHz for noise attenuation
• Designed for direct clamping onto cables without additional hardware

Applications

• Suppression of common-mode noise on power cables
• Filtering high-frequency interference on data transmission lines
• EMI mitigation in electronic equipment cabling assemblies

Procurement Notes

Verify the exact impedance value and frequency rating against the manufacturer's current datasheet before integration. Confirm that the cable diameter falls within the specified internal diameter range to ensure proper fit. Check for RoHS compliance status and lead times directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when a solid, non-hinged ferrite solution is required for cables with diameters up to 19.10 mm. Consider the 97 Ohm impedance profile at 100 MHz for compatibility with target noise frequencies. Ensure physical space allows for the 31.10 mm external diameter and 15.50 mm length constraints.

Part Context

This part belongs to the Leader Tech Inc. cable ferrite product line, specifically categorized under solid cores. It is distinct from hinged or split-core designs, offering a permanent installation method for cables that do not require frequent disconnection during maintenance or assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching internal diameter, impedance characteristics, and physical dimensions before considering alternative components.
