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 […]
New power-backup source for data centers: Supercapacitors
Price points for supercapacitor technology are declining and the standards for backup times in data centers are dropping, says power systems manufacturer Inventus Power in Woodridge, Ill. So it makes sense for supercapacitors to become an alternative technology to Lithium-ion and lead acid batteries, the company says. Consequently, Inventus Power is has developed supercapacitor products […]
Series-connected supercaps sport low leakage, low ESR
AVX Corporation has released a new series of supercapacitor modules. Comprised of series-connected cylindrical, electrochemical, double-layer supercapacitors, the new SCM Series supercapacitor modules are currently available in two voltage ratings (5V and 5.4V), and exhibit optimal pulse power handling characteristics, including: high capacitance values (0.47F – 7.5F ±20% tolerance), low ESR (4mΩ – 300mΩ at 1,000KHz), […]
