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 […]
Supercapacitor packs get CE mark
Power management company Eaton today announced that its XLM Supercapacitor product (XLM-62R1137A-R) completed the CE mark self-certification for meeting the European safety requirements. Eaton is the first manufacturer to complete the testing and certification process for a supercapacitor product. Additionally, the company completed the UL testing and certification process for the XLM product and will add the […]
Supercapacitor backup power management module for 2.9 to 5.5-V supply rails
Analog Devices announces the Power by Linear LTC4041, a complete supercapacitor backup power management system for 2.9V to 5.5V supply rails that must be kept active during a main power failure. Supercapacitors have higher power density than batteries, making them ideal for systems requiring high peak power backup for short periods of time. View the LTC4041 product […]
PCBs automatically balance two-cell supercap low-voltage systems
Two-Channel printed circuit boards provide production-ready automatic balancing for two-cell supercapacitor low-voltage systems. The SABMB2 offers over-voltage protection and ultra-low power usage for supercapacitors required in industrial controls, remote monitoring, and battery backup applications. Developed by Advanced Linear Devices Inc., the PCB balances leakage current, manages over-voltage and dissipates zero power. Each SABMB2 balances two […]
Hot swappable supercapacitor backup power controller provides uninterrupted power
Analog Devices announces the Power by Linear LTC3351, a supercapacitor charger and backup power controller IC that includes hot-swap front-end protection and all the features necessary to provide a complete, standalone capacitor-based backup power solution. The LTC3351’s integrated hot swap controller and circuit breaker use N-channel MOSFETS to provide a low loss power path from the […]
MOSFET PCBs balance high-voltage supercapacitors via low-power leakage-current regulation
High-voltage supercapacitor balancing printed circuit boards are designed to automatically control leakage current and enhance reliability for applications used in data center, industrial automation, public utility, and transportation systems. ALD SABMB810028 boards built with ALD810028SCLI SAB (supercapacitor auto-balancing) MOSFETs provide balancing for 2.8-V, 3.0-V and 3.3-V supercapacitors arranged in a series stack by equalizing the […]
The fundamentals of supercapacitor balancing
The low voltage available from a single supercapacitor forces most applications to use several supercaps in series. Here are the tricks involved in stringing these components together. Robert Chao | Advanced Linear Devices Inc. The average supercapacitor has a maximum charging voltage of between 2.5 and 2.7 V. For many applications a voltage this low […]
