The main objective focused on the design, fabrication...

source: Exxelia SAS, ESA SPCD 2018 Symposium EPCI e-symposium library article The aim of this work is the development of miniaturized filtering multilayers ceramic capacitors, single or multi capacitance, from various designs, circular miniaturizes shapes, or custom-design shapes. These special designs, for the most reduced dimensions, are only accessible by green machining of the MLCC’s. This step is one of the most critical in...

C 2.8   COMPARISON DIAGRAMS, ORGANIC DIELECTRICS This page summarizes basic overview of film and foil organic dielectric capacitors. The various dielectric types were described in more details on previous pages: POLYESTER (PET) / KT / MKT and POLYETHYLENE NAPHTALATE (PEN) Organic Dielectric Capacitors POLYPROPYLENE (PP) / KP / MKP and POLYCARBONATE (PC) / KC / MKC Organic Dielectric Capacitors POLYSTYRENE (PS), POLYPHENYLENE SULFIDE (PPS),...

C 2.6 POLYSTYRENE (PS) and POLYPHENYLENE SULFIDE (PPS) Polystyrene (PS) represents a non-polar dielectric material that just as polycarbonate to a great extent has been replaced by polypropylene. The availability is strongly limited due to ceased production. Polyphenylene Sulfide or simply PPS has come to stay mainly because of its relatively high temperature resistance which has allowed SMD manufacture. C 2.6.1  General comments to...

C 2.4  POLYPROPYLENE (PP) / KP and MKP In the book we use the common European abbreviations KP for film/foil and MKP for metallized film. C 2.4.1 Introduction Polypropylene (PP) is from a molecular point of view a non-polar dielectric with small losses and a relatively straight and moderate TC. Since the smallest film thickness is approx. 3.5 μm (0.14 mils) and εr ≈ 2.3...
