CA28B1937

Overview

The CA28B1937 is a ferrite clamp-on core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression on cables. It features a round shape with material grade 28, providing high impedance characteristics. The component has an inner diameter of 10.8 mm and an outer diameter of 30.2 mm. External dimensions include a length of 30 mm, width of 30.2 mm, and height of 19.8 mm. It utilizes a snap-fit installation type with a button base and is supplied in bulk packaging.

Feature Summary

• Snap-on hinged design allows for easy installation around existing cables without disconnection
• Utilizes material grade 28 for effective high-frequency noise attenuation
• Round barrel shape accommodates single round cable configurations

Applications

• EMI suppression on round cables
• High impedance noise filtering in electronic interconnects
• Cable bundle shielding applications requiring snap-fit mounting

Procurement Notes

Verify the specific mounting configuration, as some sources indicate adhesive base options while official specifications cite press-fit with button. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as documentation references vary. Ensure the selected variant matches the required inner diameter tolerance for the target cable assembly to guarantee secure fitment.

Selection Notes

Select this component when a round ferrite core with snap-on convenience is required for cable bundles. The material grade 28 offers specific impedance characteristics suitable for high-frequency interference. Consider the external dimensions to ensure adequate clearance within the enclosure. Verify if the standard press-fit button base meets the mechanical retention requirements of the application.

Part Context

Leader Tech Inc. specializes in EMI/RFI shielding technologies for circuit boards, enclosures, and interconnects. The CA28B1937 belongs to their ferrite clamp-on cores product line, which provides passive noise suppression solutions. These components are commonly used in industrial and commercial electronics to mitigate conducted emissions without modifying the cable structure.

Replacement Considerations

CF28B1937 shares identical physical dimensions and material grade but may differ in base configuration details. HI28B2038 and HF28B2039 utilize square shapes and different inner diameters, making them unsuitable direct substitutes for round cable applications.
