Capacitors are manufactured in many styles, forms, dimensions, and from a large variety of materials. They all contain at least two electrical conductors, called plates, separated by an insulating layer (dielectric). Capacitors are widely used as parts of electrical circuits in many common electrical devices.
Film and foil capacitors are typically potted for internal protection with a very soft, gel type material. ELANTAS Europe offers a broad portfolio of epoxy and polyurethane compounds to ensure the safety and reliability of these capacitors, ranging from very soft to rigid and stiff materials. Self-extinguishing Behaviour Thermal Resistance
ELANTAS Europe offers a full portfolio of materials for protecting capacitors in different applications and environments, including one and two component epoxy resins, two component polyurethane resins, soft gels and polyimide varnishes.
While, in absolute figures, the most commonly manufactured capacitors are integrated into dynamic random-access memory, flash memory, and other device chips, this article covers the discrete components. A dielectric material is placed between two conducting plates (electrodes), each of area A and with a separation of d.
The types of capacitor available range from very small delicate trimming capacitors using in oscillator or radio circuits, up to large power metal-can type capacitors used in high voltage power correction and smoothing circuits.
The plastic films used as the dielectric for film capacitors are polypropylene (PP), polyester (PET), polyphenylene sulfide (PPS), polyethylene naphthalate (PEN), and polytetrafluoroethylene (PTFE). Polypropylene has a market share of about 50% and polyester with about 40% are the most used film materials.
