Polymer capacitors

Panasonic is a leading manufacturer of specialty polymer aluminum capacitors, such as SP-Caps, OS-CON and POS-CAP devices, as well as polymer hybrid aluminium electrolytic capacitor technologies.

  • 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.
