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 […]

Newark has broadened its portfolio of passive devices with the addition of the new supercapacitor modules from Eaton, enabling design engineers to optimize equipment footprints, improve efficiency and reduce costs. This supercapacitor line includes highly reliable, high power, ultra-high capacitance energy storage devices that are tailored to work with applications for backup power, pulse power, […]
Supercap modules provide 51.3 V, target rugged apps
Power management company Eaton today announced its latest release of the XLR-51 supercapacitor module. The latest design extends the XLR module family to 51.3 volts (V) and 188 farads (F) and is ideal for rugged applications with harsh environments such as transportation, marine, grid storage and material handling. The XLR Supercapacitor modules provide efficient energy storage […]
Get ready for supercaps with 5x boost in power/energy density
Supercapacitors based on carbon nanotube technology are about to make the jump from laboratory curiosity to mass production. NAWA Technologies in France says it will soon begin the mass production phase of its next-generation ultracapacitor, the Ultra Fast Carbon Battery. Over the coming year, a first-of-its-kind ultracapacitor cell production line will be installed at the […]
Cylindrical supercaps include smallest 1 F, 2.7-V version
AVX Corporation has released a new series of cylindrical, electrochemical, double-layer supercapacitors. Rated for 2.7V and delivering high capacitance values (1F – 3,000F), low ESR (0.16mΩ – 200mΩ at 1,000KHz), low leakage (6µA – 5,800µA), high energy density (1.2 to 5.6Wh/kg), and long lifetime performance (50,000+ cycles), the new SCC Series supercapacitors exhibit excellent pulse […]
Supercapacitors work at 3 V for rewable energy, industrial uses
Maxwell Technologies, Inc. announced the launch of a new full-featured 3.0-volt (3.0V) product platform. With the introduction of these next-generation ultracapacitors, users have the ability to increase energy and power in the same form factor as the 2.7-volt product line and can significantly cost-optimize their system designs by using fewer ultracapacitor cells or modules. Alternatively, users […]
Zero-power board automatically balances supercapacitors of all sizes
Advanced Linear Devices Inc. announced its six-channel supercapacitor automatic balancing (SAB) PCB. The SABMB6 can balance any size of supercapacitor with zero added power dissipation. Each PCB can balance up to six supercapacitors stacked in a series, ranging in size from six to hundreds of supercapacitors with capacities from 0.1 to 3,000 Farads in voltages of […]
