Panasonic polymer capacitors

06 May, 2014

The SP-Cap, POSCAP, OS-CON and Polymer Hybrid capacitors from Panasonic provide high efficiency and low ESR alternatives to traditional capacitors. The range benefits from lifetime extension as well as high safety and reliability.


Sprague Goodman SGNM Series high-voltage non-magnetic variable capacitor

20 March, 2014

Sprague Goodman Electronics has expanded its non-magnetic variable capacitor product line with the SGNM Series. The product is claimed to be the first high-voltage (up to 12 kV) non-magnetic ceramic dielectric trimmer capacitor line for MRI and NMR applications. It is internally sealed to withstand external pressure of up to 40 psi and has residual magnetic value less than 20 nT.

21 February, 2014 by ACS Nano

Researchers have developed a way to shrink capacitors even further, which could accelerate the development of more compact, high-performance next-gen devices.


New supercapacitor stores energy on silicon chips

25 October, 2013

Researchers have developed a supercapacitor out of silicon so it can be built into a silicon chip along with the microelectronic circuitry that it powers. In fact, it should be possible to construct these power cells out of the excess silicon that exists in the current generation of solar cells, sensors, mobile phones and a variety of other electromechanical devices, providing a considerable cost savings.


Enhanced yet affordable material for supercapacitors

12 July, 2013

Researchers at Ulsan National Institute of Science and Technology (UNIST) have developed a new method to massively synthesise enhanced yet affordable materials for supercapacitors.

03 May, 2013

Electroactive polymers have been used for some time in actuators, capacitors and nanocomposites but, with new recent technical progress, come new growth opportunities.


Building a better capacitor with manganese dioxide nanorods

26 April, 2013

A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors.


All eyes on supercapacitors

26 February, 2013 by Dr Peter Harrop, Cambridge, UK

Supercapacitors (ultracapacitors) are now centre stage for designers of electronics and particularly power circuits. This is because they are improving faster than the batteries and electrolytic capacitors they increasingly replace. Supercapacitors Europe 2013, forming part of IDTechEx’s premier technology events, is being held in Berlin, Germany, 17 to 18 April.
