Arnold Technologies (Shenzhen) Ltd., doing business as Micrometals Arnold Powder Cores is a division of Micrometals
Incorporated. The Micrometals Arnold Powder Core factory is located in Shenzhen, China with a sales office in Hong Kong.
Micrometals Inc. acquired the powder core division from Arnold Magnetic Technologies in January 2010. Micrometals Inc. is
headquartered in Anaheim, California.
Warranty
Parts are warranted to conform to the specifications in the latest issue of this catalog. Micrometals Arnold Powder Core liability
is limited to return of parts and repayment of price; or replacement of nonconforming parts. Notice of nonconformance must be
made within 30 days after delivery. Before using these products, buyer agrees to determine suitability of the product for their
intended use or application. Micrometals Arnold Powder Core shall not be liable for any other loss or damage, including but not
limited to incidental or consequential damages.
Material Introducon & Overview
Introduction to Powder Cores
Powder Cores are made from discrete particles of ferromagnetic powder. Prior to being formed into a core, the
particles are covered in a thin layer of electrically insulated material to ensure electrical isolation of each
particle. The particles are then compacted under high pressure to form the core geometry. The electrical
insulation between particles enables the materials to be used at high frequency. The insulation also forms a
distributed air gap throughout the core material, giving the material the ability to maintain inductance linearity
with a DC biasing field.
Micrometals Arnold Powder Cores manufactures 5 different classes of materials: Super-MSS™ Sendust (MS),
Molypermalloy (MP), FluxSan™ Iron Silicon (FS), Hi-Flux™(HF), and the newly introduced Optilloy™(OP). The
following table describes size and permeability ranges available for each material class, and also describes the
characteristics and applications for these material classes.

Part Numbers
Inductance Tolerance
Micrometals Arnold Powder Core part numbers are
constructed as shown below.
The cores are manufactured to the AL values listed in
this catalog with a ±8% inductance tolerance with the
exception of small (0.14 to 0.44 inches) toroidal cores
with Super-MSS™ material. Refer to catalog part page
for details.

Inductance Rating
In this catalog the inductance ratings, also known as AL
-9
values, are expressed in nanohenries (10 Henries) per
2
turn (N) squared (nH/N ).
To calculate the number of turns required for a desired
inductance (L) in nanohenries (nH) use the following
formula:
1
ª desired L (nH) º 2
Required turns «
»
2
¬ A L (nH/N ) ¼
2
Part numbers are labeled on individual parts on toroid
sizes 0.40 in. (10.2mm) and larger. Toroid part sizes less
than 0.40 in (10.2mm) are coated with Parylene N.
Parylene C is available upon request but is not RoHS
compliant.

Standard toroidal cores are all furnished with an
isolation coating. Coating type and dielectric strength
vary with part sizes, details and test conditions are
offered on the part pages. Finished are tested for
dielectric strength with conductive foam pads pressed
against the two flat surfaces and around the OD/ID
corners of the core.
Engineering kits and evaluation samples are available;
please refer to Micrometals Arnold Powder Cores
website (www.MicrometalsArnoldPowderCores.com)

Inductor Design Soware
Micrometals Arnold Powder Core Inductor Design
Software is a flexible user-friendly tool designed
to assist in the selection of powder cores. The
software file size about 4.5 MB, and is available
for free download from
www.MicrometalsArnoldPowderCores.com.
The user will have the opportunity to select from
two different inductor applications:
1) Design of DC output inductors,
typically used in Switch Mode Power
Supplies (SMPS)
2) Design of a power factor boost
inductor, commonly referred to as a
PFC choke.
The program accepts user defined design
requirements in terms of required inductance, dc
resistance, dc bias current and applied ac voltage.
The user has the option of specifying core
geometry (Toroids only in this release), specific
core materials or all materials, metric units or
English units, maximum window fill factor,
temperature rise, ambient temperature, etc.
The program will automatically calculate the
smallest core size possible and will display;
10) Core Loss
11) Copper Loss
12) Temperature Rise
*Unit price is an estimate and intended to
demonstrate relative prices between materials
and sizes and provide design engineer value
judgment and not a procurement offer.
In addition, the software allows the user to
analyze specific designs using the analysis
function.
The software allows the design engineer to
quickly work up multiple design solutions based
on user specified electrical requirements which
all can easily printed for hard copies. Designs can
also be saved to a file by using the 'F' key.
Detailed instructions can be found in the “Help”
section of the software. The Applications
department at Micrometals can offer technical
assistance regarding the use of this software and
can be contacted at the Anaheim California
headquarters at [email protected]
1) Micrometals Arnold Part Number
2) Approximate unit price*
3) Core AL Value
4) Required Number of Turns
5) Wire Size
6) Percent Window Fill
7) DC Winding Resistance
8) Bpk - Peak AC Flux Density
9) Percent Initial Permeability
