Syfer StackiCap™ Capacitors

Syfer's new StackiCap™ Capacitors are true SMD stacked capacitors designed without a mounting frame and in smaller case sizes that allow higher voltage and capacitance.  The StackiCap™ SMD Capacitors from Syfer also have a unique patent-pending construction and FlexiCap™ termination material that make this capacitor suitable for a wide range of high voltage applications where a large amount of capacitance is required. One of the major advantages of StackiCap™capacitors is significant size reduction, with a reduction from 8060 to 2220 case, for example. Smaller case sizes make these capacitors very useful when board space is limited, or at a premium.

  • Higher voltage/capacitance in smaller case sizes with increased thickness
  • Monolithic HV ceramic MLCC
  • Patented internal design with stress relieving layers to prevent electro-mechanical cracking
  • Offers significant size savings and cost savings
  • Lead-free X7R dielectric
  • Does not rely on stacking MLCCs or adding leadframes
  • Flexicap™ termination
  • Maximum capacitance up to 2.2µF
  • Maximum voltage up to 2kV
  • Power supplies
  • Lighting
  • Aerospace electronics
