Micrometals Iron Powder Cores

The iron powder cores described in this catalog are typically used for DC output chokes, differential-mode input chokes, power factor correction inductors, continuous-mode flyback inductors, light dimmer chokes and other EMI/RFI applications.

Micrometals 200C Series(TM) of magnetic alloy materials are specifically designed for severe environment applications where cores are exposed to or generate elevated temperatures. These cost-competitive core materials are not subject to thermal aging for operating temperatures up to +200°C. Revision C of this catalog introduce 2 new materials to the 60 series of materials. The -63 Material offers excellent high frequency properties while the -66 Material offers core losses that are well suited from 100kHz to 500kHz.

Iron powder has been used as a core material in RF circuits for many years. It is typically used to produce high "Q" inductors from 50 KHz to 500 MHz and broadband transformers above 50 MHz. It is preferred core material due to its stability, high "Q", frequency response, and power handling capabilities.

Micrometals new series of cores for high density inductors are well-suited for either through-hole or surface mount applications. The geometries shown in this catalog are offered in traditional iron powder -52 Material or magnetic alloy powder -65 Material. Generally, cost sensitive applications will utilize -52 Material with round wire and through-hole mounting. Space sensitive applications will use -65 Material with helical wound flat wire with bent leads for surface mounting. In addition to the two materials listed in this catalog, Micrometals can provide any standard material listed in our Power Conversion Catalog or limited materials listed in our 200C Series of high temperature materials.
