Polymer Capacitors design engineers Panasonic
Panasonic Polymer Capacitor SP-Caps OS-CON POS-CAP Polymer Hybrid

Panasonic is a leading manufacturer of  Specialty Polymer Aluminum Capacitors SP-Caps, OS-CON and POS-CAP as well as Polymer Hybrid Aluminium Electrolytic Capacitor Technologies.

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