The 2643800502 is a FAIR-RITE manufactured Toroid Core, available through Supreme Components International, an authorised distributor of electronic components. This ferrite core is specifically designed for applications requiring efficient magnetic flux paths. Made from 43 material, this uncoated toroid core offers a balance of permeability and saturation flux density. Its toroidal shape minimizes electromagnetic interference (EMI) and provides a self-shielding effect. This core is suitable for use in power supplies, inverters, and other electronic circuits where high performance and reliability are critical. The 2643800502 is ideal for creating custom inductors and transformers. Contact us for datasheets and application support.
