25A2025-0A0

Overview

The 25A2025-0A0 is a hinged ferrite core manufactured by Laird-Signal Integrity Products, designed for free-hanging cable applications. It features a circular design with an inner diameter of 7.00mm (0.276 inches) and an outer dimension of 17.90mm width by 18.40mm height (0.704" W x 0.724" H). The component provides an impedance of 331 Ohms at 300MHz. It is classified as a cable ferrite suitable for EMI suppression on wires.

Feature Summary

• Hinged snap-on design allows installation around existing cables without disconnection
• Solid ferrite construction optimized for high-frequency noise attenuation
• Free-hanging mounting style suitable for wire harness management

Applications

• Suppression of electromagnetic interference on power and signal cables
• EMI filtering in electronic equipment wiring harnesses
• Noise reduction on data transmission lines

Procurement Notes

Verify the specific impedance frequency rating of 331 Ohms at 300MHz against your target noise spectrum to ensure effective attenuation. Confirm that the 7.00mm inner diameter accommodates the cable bundle thickness. Check RoHS3 compliance status if required by your assembly specifications. Ensure the hinged mechanism integrity is maintained during handling to prevent accidental opening.

Selection Notes

Select this component when a non-invasive solution for adding ferrite shielding to existing cables is required. The hinged design eliminates the need to thread cables through solid cores. Consider the physical dimensions of 17.90mm x 18.40mm to ensure adequate clearance within the enclosure. The 331 Ohm impedance at 300MHz targets higher frequency noise profiles compared to lower impedance alternatives.

Part Context

This part belongs to the cable ferrite category from Laird-Signal Integrity Products. It serves as a passive component for electromagnetic compatibility (EMC) improvement. Unlike surface-mount beads, this free-hanging core is intended for external cable treatment. It complements other EMI suppression strategies by providing targeted noise absorption on specific wire runs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify dimensional compatibility and impedance characteristics carefully when considering alternative hinged ferrite cores from other manufacturers.
