RTHF (Hi-Flux) toroidal cores


Hi-Flux (RTHF) cores are 50% Nickel and 50% Iron distributed gapped powder core. HF has up to 15,000 Gauss saturation flax density and core losses significantly lower than iron powder cores. These cores are ideal for Switching Regulator Inductors and In Line Noise Filters. When used in applications with a high dc current, Hi-Flux cores can provide a reduction in inductor size as well as a total cost reduction.

Feryster is the official distributor of Micrometals Arnold Powder Cores. The table below shows the Hi-Flux sample list which Feryster has in stock, ensuring prototype build applications. They are available on request to all clients. For all interested parties, we offer the latest catalogues free! Designers can download Micrometals Arnold Powder Cores Software dedicated to design inductors based on Arnolds iron powder cores.
