Ultra-long life screw-terminal capacitors

It has been announced that New Yorker Electronics is distributing the newest Exxelia Sic Safco Long-Life Aluminum Electrolytic Capacitor. The Felsic HV family of aluminium electrolytic screw terminal capacitors provides great performances in energy density combined with an ultra-long lifetime.

For instance, 6,800µF @450V fit into a volume of Ø77x220mm and can withstand 200,000 hours between zero to 70°C under 37A, which makes them the perfect choice for use in rolling stock traction systems or the concurrent versioning system (CVS).

The series also has one of the lowest ESR of its class with less than 10mΩ in most cases. Products are available for voltages from 160 to 450Vdc, and offer capacitance values from 1,500μF up to 47,000μF, ensuring the best compromise between reliability and compactness.

Exxelia screw terminal aluminium electrolytic capacitors are large capacitors supporting high energy loads. High energy density and lifetime are the top features of these capacitors as they are used in hi-rel applications.

Showcased last year at PCIM Europe, the Felsic HV aluminium electrolytic screw terminal capacitor is most often used in aviation, military, medical and railway applications.

Features:

  • Long lifetime
  • High ripple current
  • High power
  • Low ESR
  • High energy density

Applications:

  • Energy storage
  • Filtering
  • Power electronics; converters, current inverters
  • Switch mode power supplies
  • Magnetisation, welding machines, flash
  • Circuit with high impulse current
