Conductive Polymer Hybrid ECAPs
Both "conductive-polymer hybrid aluminum electrolytic capacitors" and "conductive-polymer electrolytic capacitors" are types of electrolytic capacitors, each of which uses a conductive polymer material as the electrolyte. However, there are some differences in terms of construction and operation.
A "conductive polymer electrolytic capacitor" consists of two electrodes separated by a thin layer of dielectric material, usually an oxide layer on the surface of one of the electrodes. The electrolyte used in these capacitors is a conductive polymer material that allows current to flow between the two electrodes. The capacitance of the capacitor is determined by the surface area of the electrodes and the distance between them.
Hybrid design enables higher capacitance at low ESR
A "conductive polymer hybrid aluminum electrolytic capacitor", on the other hand, combines the advantages of aluminum electrolytic capacitors and "conductive polymer electrolytic capacitors." It consists of an anode made of aluminum foil, a cathode made of conductive polymer, and an electrolyte that is a combination of a liquid electrolyte and a conductive polymer material. This hybrid design enables high capacitance while maintaining the low equivalent series resistance (ESR) and low leakage current of conductive polymer capacitors, while providing the high voltage rating and high ripple current capability of aluminum electrolytic capacitors.
Both types of capacitors function similarly in that they store electrical charge on their plates when a voltage is applied to them. However, the polymer material used in these capacitors allows for a faster charge and discharge cycle compared to conventional electrolytic capacitors, resulting in improved performance in high-frequency applications.
Design differences
Overall, the main difference between "conductive polymer hybrid aluminum electrolytic capacitors" and "conductive polymer electrolytic capacitors" is in their design, with the hybrid design providing a balance between the advantages of both aluminum electrolytic capacitors and conductive polymer electrolytic capacitors.
In the end, the best technical and economical choice depends on the requirements of the specific application. We will be happy to advise you!

Advantages Hybrid ECaps
- Failure Mode = Open
Great advantage in case of defects: In failure mode, the hybrid polymer capacitor acts like a fuse in a series circuit (similar to ultracaps) - High temperature stability
Lower increase of ESR at low temperatures - Lower sensitivity to humidity
- High conductivity
- High ripple current strength in small package size
- Lower ESR compared to polymer ELKOs
- Higher dielectric strength (liquid portion of electrolyte)
- Higher volume capacitance (large effective surface area)
- Lower leakage currents than e.g. tantalum capacitors and thus
better circuit efficiency; lower intrinsic losses. - Applications: Outdoor and low-temperature applications, voltage regulation circuits, power supplies, automotive technology
