Inductor with plural linearly aligned spaced apart ferrite cores

摘要

An inductor has a winding arranged on a straight magnetic core formed by a plurality of ferrite cylinders disposed in line with one another with a space between adjacent cylinders. The ferrite cylinders are accommodated in a common cylinder made of a molded plastic material which has a helical groove in its outer cylindrical surface. The inductor is used for the injection of a low-frequency current into a cable of a CATV system.
