  • Inductor
    Patent number: 5550523
    Abstract: The inductor has a winding arranged on a straight magnetic core formed by, for example, a ferrite cylinder (4) accommodated in a cylinder (1) made of a moulded plastics material and having a longitudinal groove in its outer cylindrical surface, in which groove a bar (2) of an electrically resistive material is mounted, the bar being fixed underneath the winding wire (3). The inductor is used for the injection of low-frequency current into a cable of a CATV system.
