Kemet Provides New P295 and P278 Series Impregnated Paper EMI Suppression Capacitors

Farnell element14 has announced it is the first major distributor to market Kemet’s new P295 and P278 series impregnated paper EMI suppression capacitors.

Impregnated paper is the ideal dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. material for operating as part of an EMI capacitor in an environment where ionisation corona discharge is likely to take place. It contains no cavities, being completely filled with epoxy, and thus becomes much more resistant to ionization than alternative materials such as polypropylene or polyester, says the company.Impregnated paper capacitors also have greater self-healing properties than ones made from alternative materials, with a much lower content of conductive-free carbon. The multi-layered dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. in the P295 and P278 series, consisting of impregnated paper, ensures high stability and reliability properties, especially in applications having continuous operation. The capacitors also meet the most stringent IEC humidity class of 56 days.
