Iron powder cores may come in numerous sizes and configurations, each of which is available in different materials. However, the toroidal cores are the most efficient configuration due to its highly shelf-shielding characteristic. Iron powder toroidal core is seldom necessary to shield a toroidal inductor as most of the flux lines are contained within the core.
This toroids products offer a simple, compact solution for making inductors, coupled inductors and transformers. RF circuits, EC power supply chokes, motors dimmer control filters.
Various types of cores are designed as standard series as listed in the catalog. None standard cores may be designed and produced to meet customer's specifications as requested. The next several pages are devoted to iron Powder materials and the toroidal core configuration in particular. You will find physical dimensions of available items, their AL values and other magnetic properties, as well as how to select the proper core for your application.
