The FAIR-RITE 2643000801 is a high-quality Ferrite Toroid Core, perfect for a wide range of electronic applications. Supreme Components International is an authorised distributor of FAIR-RITE, ensuring you receive genuine components. This core is made from Material 43, known for its excellent performance characteristics. Its dimensions include an outer diameter (OD) of 12.7mm, an inner diameter (ID) of 7.62mm, and a height (H) of 4.75mm. Toroid cores are commonly used in inductors, transformers, and filters due to their ability to provide high inductance with fewer turns of wire. The closed-loop design minimizes flux leakage, resulting in improved efficiency and reduced electromagnetic interference (EMI). This FAIR-RITE core is suitable for applications requiring stable inductance and high-frequency performance.
