Printed August 2011 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. Super-MSS™ Sendust x x x x x x x Iron, Silicon, Aluminum alloy powder material Permeabilities: 14μ, 26μ, 40μ, 60μ, 75μ, 90μ and 125μ Low Magnetostriction for audibly quiet applications Cost effective low loss material Operating frequencies to MHz No thermal aging Wide selection of toroids, E-cores and blocks MPP Molypermalloy x x x x x x Nickel, Iron Molybdenum alloy powder material Permeabilities: 14μ, 26μ, 60μ, 125μ, 147μ, 160μ, 173μ, 205μ and 250μ Very low loss powder material Operating frequencies 200kHz No thermal aging Wide selection of toroids up to 154mm FluxSan™ Silicon Iron x x x x x x 6.5% Silicon, Iron alloy powder material Permeabilities: 14μ, 26μ, 40μ, 60μ, 75μ and 90μ High saturation characteristics Low losses 200kHz No thermal aging Wide selection of toroids, E-cores and blocks Hi-Flux™ Nickel Iron x x x x x 50/50 Nickel, Iron alloy powder material Permeabilities: 14μ, 26μ, 60μ, 125μ, 147μ and 160μ High saturation characteristics Moderate losses 200kHz No thermal aging Optilloy™ Optimized Alloy x x x x x Hybrid alloy powder material Permeabilities: 14μ, 26μ, 40μ, 60μ, 75μ, 90μ and 125μ Moderate losses 200kHz No thermal aging Toroids up to 154mm MICROMETALS Arnold Powder CoresÊÊUÊÊwww.MicrometalsArnoldPowderCores.com 1 Part Number Examples, Finish, Temperature Statement 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. Toroidal Core Geometry MP - 600 125 - 2 Typical Part Number: Material Type OD in 100th inches Reference Permeability Finish Inductance Grading Binning and marking in 1% grades is possible upon request. E-Core Geometry Typical Part Number: Core Finishes E FS - 055 28 25 - 090 Geometry Material Type "A" Dimension in XXXmm "B" Dimension in XXmm "C" Dimension in XXmm Reference Permeability Block Core Geometry Typical Part Number: B MS - 080 30 20 -060 Geometry Material Type "A" Dimension in XXXmm "B" Dimension in XXmm "C" Dimension in XXmm Reference Permeability Finish MS MP FS HF OP 2 = Blue Epoxy 8 = Parylene N (Standard) 8C = Parylene C Super-MSS™ Sendust MPP Molypermalloy FluxSan™ Silicon Iron Hi-Flux™ Nickel Iron Optilloy™ Optimized Alloy 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. Engineering Kits Materials = = = = = 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) for distributor or local sales contact for details. Engineering Assistance Micrometals Arnold will gladly extend engineering and design assistance to aid in your core selection. Please refer questions to [email protected]. In addition Micrometals Arnold Powder Cores offers Induction Design Software which can be downloaded at no charge. Please refer to pages 95 to 96 for details.

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 MICROMETALS Arnold Powder CoresÊÊUÊÊwww.MicrometalsArnoldPowderCores.com 95 Inductor Design Soware Example Inductor design soware is available for download at no charge from www.MicrometalsArnoldPowderCores.com 96 MICROMETALS Arnold Powder CoresÊÊUÊÊwww.MicrometalsArnoldPowderCores.com Quick Reference Super-MSSTM Sendust MPP Material Type 85% Fe 9% Si 6% Al 81% Ni 17% Fe 2% Mo Material Designaon MS Comparison made with: FluxSanTM Hi-FluxTM OplloyTM 93.5% Fe 6.5% Si 50% Ni 50% Fe Fe Si Al Ni MP FS HF OP 60μ 60μ 60μ 60μ 60μ Bsat (G) 8,900 8,800 16,700 14,800 13,000 H at 50% μi (Oe) 99 100 142 151 141 60Hz, 5000G 6.4 9.1 14.5 15.7 8.7 10kHz, 500G 12.9 12.9 26.1 18.8 11.8 100kHz, 140G 12.9 12.6 24.2 27.8 15.9 1MHz, 40G 49.0 54.6 79.1 166.5 83.5 Shapes T, E & B T T, E & B T T Max Size Toroid (T) 154mm 154mm 154mm 154mm 154mm Max Size E-Core (E) 120mm — 120mm — — Max Size Block (B) 80mm — 80mm — — Relave Price* 2-3 10 - 18 2-4 7-9 6-7 Saturaon Flux Density Core Loss *Pricing Pricing esmate relave to Micrometals least expensive iron powder material based on 25mm toroidal geometry.
