Electric Double Layer Capacitors (EDLC) / Supercapacitors


Electrical double layer capacitors (EDLC), also known as "supercapacitors," are next-generation energy storage devices with excellent cycle characteristics. Having the highest energy density of all capacitors, they close the gap between batteries and conventional capacitors. In order to achieve higher voltages, individual cells can be connected in series or parallel, allowing supercapacitor modules to be created. Although this technology has been around for some time, new applications are emerging every day, ensuring that EDLCs have a promising future ahead of them.

Features / Advantages Of Supercapacitors:

  • Cycle stability
  • Long (operating) life
  • Wide temperature range
  • Reliable under harsh / challenging conditions
  • High power density
  • Low internal resistance
  • No memory effect
  • Maintenance free
  • Excellent charge and discharge efficiency
  • Withstands acceleration forces and vibration
  • Environmentally friendly


Application Examples For Supercapacitors:

  • Transportation & Logistics Vehicles
  • Energy recuperation

Leitfähige Hybrid Polymer-Elektrolytkondensatoren / Hybridkondensatoren


Using a combination of conductive, electrical polymer materials and liquid electrolytes, conductive polymer hybrid aluminum electrolytic capacitors combine the best of both worlds. The polymer enables low electrostatic discharge resistance (ESR) and high ripple current, while the liquid electrolytes provide low leakage current and reliable short-circuit protection. In addition, the capacitors can withstand high voltages and offer higher capacitance values.

Features / Benefits of Hybrid Capacitors:

  • Excellent ripple characteristics; withstands high ripple current.
  • Very low ESR value
  • High capacitance
  • High voltage 
  • Wide temperature range (-55°C to +125°C)
  • Elimination of the risk of short circuit (dielectric self-healing function)
  • High reliability


Possible Application Examples For Hybrid Capacitors:

  • Automotive industry
  • Engine/transmission control unit
  • Infotainment and camera systems
  • Pump systems
  • DC-DC converters
  • Communication equipment
  • 5G repeater
  • Home appliances
  • Vacuum cleaner (BLDC motor)
  • TV switching power supplies
  • Medical equipment

Polymer Electrolytic Capacitors / Polymer Capacitors


Conductive polymer aluminum electrolytic capacitors use a highly electrically conductive polymer as the electrolyte. The material composition enables the capacitors to have a lower internal resistance (ESR) and to withstand higher currents. Because of the high polymer content, the electrolyte contains little liquid and therefore poses little risk of drying out. Since the polymer adapts at high temperatures, the capacitor life is not affected by temperature, resulting in longer overall durability and life. Due to their suitability for high frequency applications, polymer capacitors are ideal for digital circuits.


Features / Advantages Of Polymer Capacitors:

  • Low impedance at high frequencies (10kHz~10MHz).
  • Can withstand high ripple current due to reduced ESR
  • Excellent noise absorption characteristics
  • Very stable capacitance characteristics, impedance and ESR versus temperature
  • Longer life and high reliability


Application Examples For Polymer Capacitors: 

  • Automotive industry
  • Smartphones and "Smarthome" devices
  • TVs and flat panel displays
  • PCs and notebooks 
  • Digital cameras
