It is more competitively priced than other shapes since it is assembled using a simple procedure (EI Cores). However, these cores lack self-shielding capabilities. It's available in EI-2811, EI301, EI3313, and EI3512 sizes.
Common uses/applications for EI cores include common-mode inductors, main power transformers and line filter reactors, converter isolation safety isolator modules.
