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:
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:
Use of the hybrid electrolyte that blended electrolytic solution with conductive polymer realized low leakage current equivalent to that of aluminum electrolytic capacitors.
This feature 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:
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 1250 C and 5000 hours at 1050 C.
Applications:
- Compact and lightweight automotive equipment:
- power supplies of automotive engine ECU (Electronic Control Unit)
- various motor ECUs
- DC/DC converters
- switching power supplies for the set requiring high withstand voltage and high reliability
