Premium Electrical Capacitors

PUI Projections
A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric field. In most electronic devices capacitors are connected in parallel with the DC power circuits to smooth current fluctuations for signal, or control circuits.
 
Depending on your application there are diverse types of capacitor options available. For example, computer grade capacitors, or power capacitors are used for car audio applications to prevent other electronic components from failing when large amounts of electricity are drawn to the amplifier. However, computer grade and power capacitors can be used for most types of high voltage applications.

 


Aluminum Capacitors

An AC capacitors anode electrode is made of pure aluminum foil that features an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. Some of the features of our AC capacitors, include:
  • Computer grade quality
  • Multilayer ceramic chip
  • Snap-in style
  • Conductive polymer grade aluminum
  • Surface mount

Film & Illinois Capacitors

Film version Illinois capacitors are electrical capacitors that contain an insulating plastic film, which is the dielectric. They are sometimes combined with paper to transfer electrodes. Our film and Illinois capacitor features, include:
  • Axial leaded
  • Radial leaded
  • Polyester & polypropylene film options
  • IGBT snubbers

Ceramic Capacitors

A ceramic capacitor is a fixed-value capacitor, where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic, and a metal layer that acts as the electrodes. PUI’s ceramic capacitor features, include:
  • Surface mount
  • Various size options
  • Extreme reliability
  • Anti-sulfur design
  • Broad voltage ranges

Tantalum Capacitor

A tantalum capacitor uses a small pellet of tantalum metal that acts as an anode, which is covered by an insulating oxide layer that forms the dielectric. This portion is then surrounded by conductive material that acts as the cathode. PUI’s tantalum polymer capacitors in a full range of sizes and voltages.
