SP-Cap Capacitors

Panasonic’s industry leading SP-Cap™ Polymer Aluminium Capacitors, are surface mount (SMT) capacitors that utilize a conductive polymer as their electrolyte material in a layered aluminum design. SP-Cap™ capacitors are primarily used as input and output capacitors for DC/DC converters due to ultra-low ESR values, high voltage options, and the ability to withstand high reflow temperatures. Panasonic SP-Cap™ Polymer Aluminium Capacitors offer capacitance values up to 560µF, voltage values ranging from 2V to 25V, and are free from temperature drift.

Key Features

  • Ultra-low ESR capacitor, top class in the industry
  • Stable temperature characteristics / Frequency characteristics
  • Lineup of 1.0-mm (max.) thick low-profile products
  • High safety made possible by self-recovery function (no ignition)
  • Low ESL type adopting three-terminal structure available
  • Long life compared to general electrolytic capacitors
