The DE1205-68 Ferrocore is a type of electronic component or device used in inductors and devices that are used to store, filter, or regulate the flow of current in a circuit. It is specifically a core that consists of alnico-5 (5% aluminum, 5% nickel and 8% cobalt) and it has a high heat resistance and low coercive force, allowing it to function in a wide range of temperatures and applications. It has a moderate inductance, allowing it to be used as a choke, filter, or transformer coil. This type of core has excellent thermal stability, which makes it ideal for use in high-temperature and high-humidity environments due to its non-magnetic properties. This type of core is available in a range of sizes, including diameters from 0.250 to 1.050 inches.
