Fair-Rite Openable Diameter 25.65 mm Round Cable Snap-It Ferrite Core for EMI Suppression 0431177081

The Fair-Rite 0431177081 is an openable ferrite core featuring a round cable snap-it design, engineered specifically for electromagnetic interference (EMI) suppression in various industrial and commercial electrical systems.

This ferrite core accommodates round cables with apertures measuring 25.65 mm in diameter, suitable for cables with diameters up to approximately 25 mm. The snap-in design enables convenient installation on existing cables without the need for disassembly or cutting.

Its polypropylene case bears a UL 94-V0 flame retardant rating, ensuring high durability and safety under electrical operating conditions. The ferrite core is constructed of specialized 31 Material, optimizing its performance in EMI attenuation applications.

Performance characteristics include an impedance of 98 ohms at 25 MHz and 182 ohms at 100 MHz, effectively filtering electromagnetic noise across a broad frequency spectrum. The core's design is un-gapped, providing consistent magnetic properties and stable filtering performance.

Physical dimensions measure 27.45 mm in external depth, 56.4 mm in external width, and 42.95 mm in external height, resulting in a compact form factor suitable for use in space-constrained or industrial environments.

This Ferrite Core complies with Restriction of Hazardous Substances (RoHS) standards and is manufactured in the United States, demonstrating its adherence to international quality and safety norms.

Openable design allows easy installation on installed cables without disassembly. Diameter of the aperture is 25.65 mm, suitable for accommodating cables up to 25 mm diameter. Single aperture for controlled EMI attenuation.

Impedance of 98 ohms at 25 MHz and 182 ohms at 100 MHz ensures effective EMI filtering. Constructed with 31 Material and polypropylene case rated UL 94-V0 for flame resistance. No gapped core structure for consistent magnetic properties.
