As the technology has changed, new shapes, sizes and materials have been introduced to become industry standards. INTRODUCTION Iron powder as a core material has been widely used in RF applications for years. The distributed air gap properties inher- ent in iron powder cores also make them extremely well-suited for a variety of energy storage inductor applications. Iron powder is a cost-effective design alternative to molypermalloy powder (MPP), high flux, or sendust cores. It can also be used in place of ferrites and iron-alloy laminations requiring a gap. 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. WARRANTY Parts are warranted to conform to the specifications in the latest issue of this catalog. Micrometals 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 shall not be liable for any other loss or damage, including but not limited to incidental or consequential damages. TEL. (714) 970-9400 MICROMETALS FAX (714) 970-0400
