Expanded XP Series of Small Cell Ultracapacitors


XP ultracapacitors are engineered specifically for applications that require extra protection from high degrees of ambient humidity, which causes the escape of electrolyte vapor and can negatively affect PCB surfaces. Under biased humidity test conditions, XP products mitigate this impact at least three times longer than Nesscap’s equivalent standard cells. This gives the XP series a significant performance advantage over the competition. The products are offered in a range of capacitances, from 3F to 50F, and have been extensively tested to ensure strict performance standards and compliance with RoHS, UL, and REACH.


  • withstand high degree of ambient humidity
  • in range of capacitances from 3 to 560F
  • comply with RoHS, UL, REACH
