  • Effect of Elastic Elongation on Dielectric Strength
    to process variability in the elongation of elastomeric polymers when they are wrapped around electric coils and other components, the possibility of altering the effective dielectric strength of the insulation material arises. In this paper we examine the relation of the elongation of a silicone-based
  • A New Dielectric Analyzer for Rapid Measurement of Microwave Substrates up to 6 GHz
    This paper from Compass Technology Group presents a new measurement method based on the parallel plate capacitor concept, which determines complex permittivity of dielectric sheets and films with thicknesses up to about 3 mm. Unlike the conventional devices, this new method uses a greatly
  • Expanding the Safe Operating Area of Polypropylene Dielectric IGBT Snubber Capacitors
    handling and short circuit tolerance. This paper describes the maximum envelope for operation of the new generation polypropylene snubber capacitors in IGBT inverter applications.
  • Mie scattering distinguishes the topological charge of an optical vortex: a homage to Gustav Mie
    One century after Mie's original paper, Mie scattering is still a fertile field of scientific endeavor. We show that the Mie scattering distinguishes the topological charge of light beams with phase dislocations. We experimentally and numerically study the scattering of highly focused
  • Laser Direct Structuring LCP for Mobile Antenna Applications
    The rapid growth and global demand for wireless. communication and increasing need for more functionality in smart phones have created a need for advanced engineering resin to meet new antenna requirements for mobile devices. This paper discusses performance of new laser direct structuring LCP
  • EETimes.com | Electronics Industry News for EEs & Engineering Managers
    manufacturers may be ready to start pushing back. Could strontium titanate be high-k gate dielectric? LONDON -- Strontium titanate, a relatively well-known perovskite material, could be the dark horse to come through and provide a replacement high-k gate dielectric material at sub-25-nanometer
  • Multi-lead Organic Air-Cavity Package for High Power High Frequency RFICs
    A new air cavity package has been developed and. qualified for packaging high power RF components. The. package uses the standard outline of a conventional ceramic. package. The ceramic dielectric is replaced with a high. performance thermoplastic called QuantechTM (which is a. modified Liquid
  • Advantages and Disadvantages of Aluminum Electrolytic Capacitors
    , and aluminum electrolytic capacitors have strong electric field strength, which is dozens of times that of paper dielectric capacitors, because the medium is oxygen film.
  • Comparison of RF Terminations with BeO and ALN Substrates
    Terminations designed to dissipate significant amounts of power at RF frequencies have traditionally been fabricated on beryllium oxide (BeO) substrates. The high thermal conductivity and moderate dielectric constant make BeO an ideal choice for this application. Increased regulation regarding
  • Silicone Based Insulation Material for High Speed/Voltage Rotating Machines
    This paper introduces the key requirements for resin rich electrical insulation materials for rotating machinery. The key requirements, or stresses that insulation are subject to, are summarized as T.E.A.M. (thermal, electrical, ambient, and mechanical). Resin rich insulation materials can be based

The key requirements, or stresses that insulation are subject to, are summarized as T.E.A.M. (thermal, electrical, ambient, and mechanical). Resin rich insulation materials can be based
  • Arc Tracking and Silicone Self-Fusing Tape
    Many electrical insulation applications are designed with dielectric breakdown strength (DBS), or the voltage potential required to break through an electrically insulating material, as a major factor. While this is a good test to determine how resistive a material is through its volume it does
  • Layout and Physical Design Guidelines for Capacitive Sensing

  • NEW ADVANCES IN PRIMERLESS SILICONE INSULATION MATERIALS
    the priming step. Using primerless silicone rubber laminate insulation tape leads to a more robust application process, as well as improved material properties such as adhesion strength, dielectric strength, volume resistivity, and thermal stability. This paper presents the results of a comparative
  • Highly Conductive Insulation for Large, High-Speed Machines
    to arc tracking and dielectric breakdown. Next generation, high-speed, multi-megawatt, rotating machines provide an insulating challenge for traditional silicone-impregnated fiberglass and epoxymica stator-coil-insulation systems. A high frequency voltage supply for these rotating machines is required
