AS25B2037

Overview

The AS25B2037 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression. It features an internal diameter of 8.90mm and external dimensions of 36.80mm in length, 20.10mm in width, and 19.6mm in height. The component exhibits an impedance of 390 Ohms at 700MHz. Constructed from material grade 25, it utilizes a snap-fit hinge design for secure attachment to cables.

Feature Summary

• Hinged snap-fit design allows for easy installation and removal around existing cable assemblies without disconnecting wires.
• Material grade 25 formulation provides specific frequency-dependent attenuation characteristics for EMI suppression.
• Free-hanging or adhesive mounting options accommodate various mechanical integration requirements.

Applications

• Suppression of electromagnetic interference on single cable assemblies
• Wire harness noise reduction in electronic equipment
• Cable shielding solutions for signal integrity maintenance

Procurement Notes

Verify the exact impedance value at the target operating frequency against application requirements, as ferrite performance varies with frequency. Confirm that the cable diameter falls within the specified internal diameter tolerance to ensure proper fit and magnetic coupling efficiency. Check RoHS compliance status if required by end-product regulations.

Selection Notes

Select this component when a reusable, non-destructive mounting solution is required for cable shielding. Ensure the cable diameter matches the 8.90mm internal dimension. Consider the mechanical stability of the hinge mechanism for environments subject to vibration or movement during operation.

Part Context

This part belongs to the FerriShield line of ferrite clamp-on cores produced by Leader Tech Inc. These components are engineered for flexible mounting options and frequency-specific formulations. The product series targets OEMs and distributors seeking reliable EMI shielding solutions for diverse cable types.
