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

Impregnated paper is the ideal dielectric 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 dielectric 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.
