These cores are less expensive than Pot cores and easier to wind bobbins. They do not regard themselves as already being protected/shielded.They are available in a variety of sizes, including EE10028, EE1011, EE11036, EE12820, and EE1306 B and C. These Ferrite E Cores are used in applications such as differential, power and telecom inductors, broadband, and inverter transformers.
