The Accu-L Multi-Layer Inductor for High Frequency Applications

The Accu-L Multi-Layer Inductor for High Frequency Applications Written By: Barry N. Breen | Chaim Goldberger | Leonid Talalavsky Abstract: The telecommunications industry today is undergoing changes. The miniaturization of electronic circuits and the use of higher frequencies in radio communication systems such as Cellular Telephones, PCN and GPS places new demands on passive components. High frequency inductors have not kept pace with the demands. AVX has responded to these requirements by putting to market a miniature (0805) high frequency SMD inductor based on thin film technology. This article presents the basic concepts of high frequency inductors and how such low value inductors are measured and characterized. Here, too, there is a lag between the high frequency designer’s need for

Film Technology To Replace Electrolytic Technology

Film Technology To Replace Electrolytic Technology Written By: Gilles Terzulli | Billy W. Peace Abstract: Since 1980, great improvements have been made on DC filter capacitors using a combination of metallized plastic films and different segmentations of the metallization on those film dielectrics. Volume and weight have been reduced by a factor of 3 or 4 over the last years. Now film manufacturers have developed thinner films and have improved segmentation techniques used on the metallization which has helped immensely in the improvement of such capacitors. Using non-gas impregnated designs, the voltage ranges between 600 VDC and 1200 VDC can be more economically covered by film capacitors rather than electrolytic. Depending on the application, over 1200 VDC, vegetable oil-filled versions

Energy and Power Handling Capabilities of Thin Film and Ceramic Capacitors

Energy and Power Handling Capabilities of Thin Film and Ceramic Capacitors Written By: Ben Smith Abstract: A continual growth of uncertainty and misconception has been prevalent in determining the power and energy capabilities of both ceramic and silicon capacitors. As today’s systems are subjected to increasingly more stringent requirements, designers are faced with numerous situations where the components that are used dictate design configurations. This paper addresses the concepts associated with a capacitor’s ability to withstand power and energy. Both theoretical and empirical models are developed and used to provide design guidelines.

Film Technology To Replace Electrolytic Technology in Wind Power Applications

Film Technology To Replace Electrolytic Technology in Wind Power Applications Written By: Gilles Terzulli Abstract: Aluminium electrolytic capacitors present serious challenges for the designer of high voltage power systems required in the very latest wind energy applications. In contrast, film technology offers significantly improved life expectancy, environmental performance and power handling capability.

Dielectric Absorption of Multilayer Organic (MLO™) Capacitors

Dielectric Absorption of Multilayer Organic (MLO™) Capacitors Written By: Edgardo Menendez Abstract: Capacitors with Dielectric Absorption (DA) recover some of their charge even after the capacitor has been fully discharged (see Figure 1). (Ref. 2) It is expressed in percentage and it is based on the measured voltage after discharging and charge recovery divided by the maximum voltage that was originally applied (see Equation 1)…

Introduction to Choosing MLC Capacitors For Bypass/Decoupling Applications

Introduction to Choosing MLC Capacitors For Bypass/Decoupling Applications Written By: Yun Chase Abstract: Methods to ensure signal integrity using decoupling capacitors have been the topic of many papers in the past as well as in the present. One can find equally many methods of decoupling as well. This paper will illustrate one of these established methods and introduce it in a theoretical sense using the most simplistic of terms. The paper will also describe the methods of the past (in slow speed systems) and the practices of the present (in high speed systems).
