AS20B2037

Overview

The AS20B2037 is a hinged ferrite core manufactured by Leader Tech Inc., designed for cable EMI suppression. It features a snap-on installation method and free-hanging configuration. The component has an inside diameter of 8.90 mm (0.350 inches) and an outside diameter of 20.10 mm (0.791 inches). Its length measures 36.80 mm (1.449 inches). This square-shaped ferrite clamp is intended for round cables and wires, providing frequency-specific shielding solutions.

Feature Summary

• Hinged snap-on design for easy installation around existing cables
• Free-hanging configuration allows flexible mounting options
• Square shape optimized for specific cable diameters

Applications

• EMI suppression for round cables and wires
• Cable shielding in electronic equipment
• Frequency-specific noise reduction applications

Procurement Notes

Verify the exact impedance value at the required frequency from the official datasheet, as distributor descriptions may omit this critical parameter. Confirm that the 8.90 mm inner diameter matches the target cable size precisely. Ensure the hinged mechanism is suitable for the application's maintenance requirements. Check RoHS compliance status if environmental regulations apply to the end product.

Selection Notes

Select this part when a reusable, snap-on ferrite solution is needed for cables with an 8.90 mm diameter. The hinged design facilitates installation without disconnecting cables. Consider the square cross-section for space-constrained environments. Verify that the material formulation meets the specific frequency range of the interference being suppressed.

Part Context

Leader Tech Inc. produces the FerriShield line of ferrite components, known for extensive inventory and frequency-specific formulations. The AS20B2037 belongs to the cable ferrite category, specifically designed as a clamp-on core. These components are widely used by OEMs and distributors for EMI shielding needs across various industries.

Replacement Considerations

Check for direct substitutes within the Leader Tech SS or AS series with matching inner diameters. Ensure any replacement maintains the hinged design and similar physical dimensions. Verify impedance characteristics at the operating frequency to maintain effective EMI suppression performance.
