Editor’s note: This cooperation is significant. Batteries and capacitors each store electric power in different ways and with different advantages and drawbacks. Properly connecting the two would allow taking advantage of the plusses of each and thereby overcoming their drawbacks. Resulting products could be useful in cars and storing power off grid.

125-V module OK for vehicles in Europe
Maxwell Technologies says the North American office of United Kingdom’s Vehicle Certification Agency (VCA) has granted European Economic Community (EEC)-Type Approval and Conformity of Production (CoP) clearance to Maxwell’s 125-volt Heavy Transportation Module (HTM125). The 125V heavy transportation series of ultracapacitor modules is a high performance energy storage and power-delivery product line for hybrid buses…
Ceramic capacitor could store energy from wind and solar
Researchers at Rensselaer Polytechnic Institute are leading a $2 million study to help widen a bottleneck that is slowing proliferation of large-scale wind and solar power generation. The four-year study aims to develop novel ceramic materials for use in a new approach to energy storage. Rather than batteries, the researchers will develop nanostructured capacitors to…

A manufacturer of advanced passive components and interconnect equipment has made enhancements to its SpiTan software for simulation and modeling of tantalum capacitors. Features in SpiTan III include the effects of temperature and voltage on DCL leakage current, equivalent circuits of capacitors with parameter values, and more than 80 new released codes. The company has…
Capacitor Delivers High Current and Low ESR
A passive components manufacturer has developed a multilayer capacitor (MLC) chip that uses a dielectric and internal electrode materials that allow for a significantly lower equivalent series resistance than previous versions. Designated the UQ Series by developer AVX Corp, the chips are well suited for RF/microwave applications ranging from 10 MHz to 4.2 GHz. “The…
