CF28B0937

Overview

The CF28B0937 is a round ferrite clamp-on core manufactured by Leader Tech Inc. It utilizes material grade 28 and features a snap-on press-fit base with a button for secure cable attachment. The component has an internal diameter of 10.8 mm (0.425 inches) and an external diameter of 27.4 mm (1.079 inches). Its length measures 1.291 inches (32.8 mm). The unit provides an impedance of 117 Ohms at 100 MHz and is supplied in bulk packaging.

Feature Summary

• Snap-on hinged design allows for easy installation onto existing cables without disconnection
• Press-fit base with button ensures secure retention on the cable
• Round shape accommodates single round cables effectively

Applications

• Suppression of common mode noise on round cables
• EMI filtering in electronic equipment cabling
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific suffix and physical dimensions against the official datasheet to ensure compatibility with target cable diameters. Confirm that the snap-fit mechanism meets the mechanical retention requirements of the assembly environment. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a round ferrite core with a snap-on installation method is required. Ensure the cable diameter falls within the 10.8 mm internal diameter limit. Consider the 117 Ohm impedance at 100 MHz for frequency-specific noise suppression needs. Verify that the free-hanging or press-fit mounting style suits the enclosure constraints.

Part Context

This part belongs to the Leader Tech ferrite clamp-on cores series, specifically designed for cable EMI suppression. It is categorized under ferrites and uses material grade 28 for its magnetic properties. The product is distinct from sleeve or split-core types due to its integrated snap-fit base.

Replacement Considerations

Cross-reference with other round ferrite cores featuring similar internal diameters and snap-fit bases. Verify impedance characteristics match the application requirements before substitution.
