La
geometría del núcleo E ofrece un diseño económico para un ancho rango de
aplicaciones . En ferrites de potencia, los núcleos E son usados en una
amplia gama de diseños para potencia, y los núcleos U son frecuentemente
usados en choques de salida, filtros de enterada en potencia y transformadores
para fuentes conmutadas y balastos HF.
Ambos
núcleos están disponibles en material 77.
