Development of Surface Mount Type (SMD) / Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

 ELNA has recently developed "conductive polymer hybrid aluminum electrolytic capacitors", which combined advantages of both aluminum electrolytic capacitors and conductive polymer capacitors.

This new product incorporated the hybrid electrolyte, that blended electrolytic solution (liquid) with conductive polymer (solid) using the unique electrolyte technology.

Features:

  • Low ESR, high ripple current
    The above feature: 
    - Use of the hybrid electrolyte that blended electrolytic solution with conductive polymer realized low ESR and high ripple current equivalent to those of conductive polymer capacitors.
  • Low leakage current
    The above feature:
    - Use of the hybrid electrolyte that blended electrolytic solution with conductive polymer realized low leakage current equivalent to that of aluminum electrolytic capacitors.
    - Will contribute to reduction in power consumption and stability in operation for various devices because in automotive power supplies, leakage current of capacitors may increase the dark current in some circuits during an engine stop.
  • High temperature, long life
    The above feature:
    - Use of the technologies to lower evaporation of electrolytic solution by hybrid electrolyte and to reduce thermal deterioration by conductive polymer realized guaranteed 4000 hours at 1250C and 5000 hours at 1050C.
  • High reliability and maintenance-free operation for the set
