The role of polymer capacitors in the development of GAN-based AC/DC Converters

Polymer capacitors can contribute to better efficiency and miniaturization of design by offering lower ESR and higher ripple current characteristics in smaller case sizes.

  • Low ESR is realized by using conductive polymer.
  • Ideal for noise reduction across a wide frequency domain thanks to the large capacitance and low ESR offered.
  • The temperature characteristics of conductive polymer are very stable for ESR and capacitance.

Our conductive polymer capacitors range

capacitor polymer sp-cap
Polymer Aluminum Capacitors


SP-Cap is a rectangular chip-shaped aluminum electrolytic capacitor that uses a polymer as its electrolyte.
capacitor polymer poscap
