FDDesign
GENERAL DESCRIPTION
FD series use metallized dielectric, controlled self-healingtechnology, high specific energy.
USUAL APPLICATIONS
The FD
capacitors are designed for discharge applications
such as Laser, electronic flash, cardiac defibrillator, etc.FDseries offer a very high specific energy level, higher than1500J per liter for cardiac defibrillator application.
