The most important benefits of
using PCB-mountable supercapacitors

PCB-mountable supercapacitors - designed for efficient assembly.

Introducing the new, high-performance PCB-mountable supercapacitors. These components are designed to be efficient and cost effective while providing excellent long term stability for your system!

Energy density
Next-generation SkelCap supercapacitors.

In a major breakthrough for energy storage solutions, Skeleton Technologies has created PCB-mountable supercapacitors that are both efficient and powerful with low internal resistance. These high-performance cells can be used in many different applications to provide power backup or quickly charge a variety of different applications.

High power profiles
Lowest heat generation under high power profiles.

Thanks to their ability generate low levels of heat, PCB-mountable supercapacitors are being used in a variety of applications where power is essential but heat generation needs to be minimized.

Longest lifetime
Longest application lifetime of up to 15+ years.

The new energy storage solution is here to meet our growing demand for power. Not only does it have an application lifetime of 15+ years, but these PCB-mountable supercapacitors can charge quickly and deliver instant stability when you need it most! The SkelCap cells are not just reliable - they're also environmentally friendly.
