Micrometals-Arnold Powder Cores

Products include:

MPP
Molybdenum Permalloy Powder (MPP) cores provide the maximum Q and lowest core losses of all commonly available powder toroids. MPP is the most stable core with respect to temperature and AC Flux. It has the widest range of permeabilities and is considered the premium material for direct current output inductors of Switched Mode Power Supplies.

HI-FLUX™
HI-FLUX™ (HF) cores are a 50% Nickel - 50% Iron distributed gapped powder core. HF has up to 15,000 Gauss saturation flux density and core losses significantly lower than iron powder cores. When used in applications with high DC current, HF cores can provide a reduction in inductor size as well as total cost.

SUPER-MSS™
SUPER-MSS™ utilizes an iron-silicon-aluminum alloy powder which has high resistivity and low magnetostriction. A 10,000 Gauss saturation level provides high energy storage at a lower total loss compared with iron powder or gapped ferrites, and at lower cost than MPP.

Iron/Silicon
The 6.5 wt% Iron-Silicon material offers significant advantages, displaying excellent soft magnetic properties such as high saturation magnetization, near zero magnetostriction and higher resistivity.
Iron/Silicon powder cores have a typical 15,000 Gauss saturation flux density and core losses significantly lower than iron powder cores at high frequencies.

Areas of Specialization:
Micrometals Arnold Powder Cores can supply a wide range of standard toroid O.D. sizes, from 0.14 inch (3.6 mm) to 5.218 inch (133 mm), and is also capable of providing non-standard, customer specified physical dimensions..

Company Background:
The Arnold Powder Core Division was acquired from Arnold Magnetics Technologies by Micrometals Incorporated of Anaheim, California in January of 2010. Arnold’s extensive range of MPP (molypermalloy powder), SUPER-MSS™ (sendust), HI-FLUX™ (50/50 nickel iron), Iron/Silicon and other alloy based powder cores are manufactured in large quantities with competitive pricing and outstanding quality in Arnold’s Shenzhen, China factory.
