A new series of higher-voltage and high-energy-density supercapacitors, called DSF Supercapacitors, offer a notable jump in voltage rating over typical supercapacitors to 3.0 WVdc for a single component and 6.0 WVdc for a dual-pack device. This higher voltage spec results in greater energy densities, which in turn saves space and may reduce the number of […]

What’s new in electrolytic capacitors and supercapacitors for energy harvesting
By Suzana Jankuloska, Product Manager at KEMET Corporation Capacitors developed for energy-harvesting applications bring improvements to equipment of all types and sizes, from directly powered IoT devices to grid-connected generators Nothing new under the sun? Ambient energy has been present in Earth’s ecosystem since the beginning of time. Humans have a long history of finding […]
Supercapacitor system design considerations
Supercapacitors can deliver more: More power density, more Farads, more cycle life, and so on. But they also demand more complex solutions to realize optimal performance. Among the many design considerations are managing supercapacitor discharge, optimizing supercapacitor charging, and, in the case of series configurations of supercapacitor modules, providing effective voltage balancing between cells. Properly […]
Supercapacitor specifications and IEC/EN 62391–1
When correctly used, supercapacitors can support high power levels, high pulse power loads, and long-term back-up power needs. Understanding the nuances of supercapacitor specifications is the key to maximizing these performance capabilities. There is some level of standardization for supercapacitor sizes, for example, a 10x30mm can supercapacitor is generally 10 Farads across the industry. Some […]
Supercapacitor operation – a higher power source
Thousands of Farads and power densities of thousands of watts per kilogram are among the chief benefits of supercapacitors (also called ultracapacitors). These devices operate in a fundamentally different way compared with conventional capacitors or batteries. Most supercapacitors commonly used today are double-layer capacitors which provide high power capabilities. Pseudo-capacitors are a less common form […]
Applying large banks of supercapacitors
It pays to know techniques for mitigating leakage current and over- voltages in uses where several supercapacitors work in parallel. Michele Kinman Advanced Linear Devices Inc. In applications requiring rapid charge/discharge cycles or short-term energy storage, you’ll often find supercapacitors connected in series or parallel. However, there’s a potential problem when supercaps are wired together […]
CAP-XX acquires Murata supercapacitor production lines
CAP-XX announced it will acquire CAP-XX licensee Murata’s supercapacitor production lines, relocate them from Japan to a new factory in Sydney to arrive in stages between March and June 2020, and begin producing Murata’s three supercapacitor product families in Q3 2020. Murata will also assist in introducing CAP-XX to its customers. Murata licensed CAP-XX’s patents […]
Energy efficient supercapacitor cell balancers include over-voltage protection
The precision dual-channel SABMBOVP2XX family of products automatically balances supercapacitors with the addition of over-voltage protection (OVP). The result is energy-efficient supercapacitor balancing, ideal for products that require low-loss energy power, leakage current regulation, and OVP. Supercapacitor cells typically operate at a nominal recommended working voltage. However, voltages that exceed the maximum rating for a […]
