Supercapacitors now come in a small, thin format that makes them candidates for uses characterized by cramped quarters. Shinji Higuma, TDK Corp. In the next several years, the internet of things (IoT) will include tens of billions of connected devices. Consumer, industrial, medical, and automotive applications will feature connected devices, but not all connected devices […]

Putting supercapacitors to work
There are a variety of modern applications in which supercapacitors are better candidates than either batteries or ordinary capacitors. George Wundsam, Cornell Dubilier Supercapacitors are not new. First developed in the 1950s, commercial versions were marketed over 40 years ago. At that time, supercapacitors were certainly not on a fast track to practical application. They […]
Miniature supercapacitors qualified for automotive uses
KEMET announces its new high-performance supercapacitors for automotive electronics, the FMD, and the FU0H series. This series delivers 1,000 hours at 85°C/85% RH-rated voltage and operating temperature ranging from -40°C to 85°C. The FMD series offers the highest lifetime with up to 4,000 hours. These supercapacitors are qualified for an automotive testing protocol. These capacitors […]
Supercaps boast wide operating temperature range, high energy density
AVX Corporation has launched a superlative new series of standard and custom supercapacitors engineered to provide peak performance in an array of SWaP-optimized, battery-powered products. The new SCP Series PrizmaCap supercapacitors have the widest operating temperature range of any supercapacitor technology currently available on the market (-55°C to +90°C), the highest capacitance (3.5–15F), and energy density (1.14–2.43Wh/kg) […]
Energy storage by the Farad, Part 3: Hybrid supercapacitors
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. Just as with rechargeable batteries, supercapacitors need proper management to optimize their performance and avoid mishaps. In many ways, the supervisory requirements for both are similar but there are some differences. Vendors of power-management ICs […]
Energy storage by the Farad, Part 2: Supercapacitors & batteries
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. The previous part of this article established the context for supercapacitors and explained their structure in simplistic terms; obviously, this is a component with deep physics, chemistry, materials-science considerations, and manufacturing issues. The first widely […]
Energy storage by the Farad, Part 1: Supercapacitor basics
Engineers can choose between batteries, supercapacitors, or “best of both” hybrid supercapacitors for operating and backup power and energy storage. Many systems operate from an available line-operated supply or replaceable batteries for power. However, in others, there is a need in many systems to continually capture, store, and then deliver energy to power the system. […]
Supercapacitor line now ranges from coin cell, radial form factors, large snap-in types
New Yorker Electronics has announced its distribution of the newly expanded Cornell Dubilier line of Supercapacitors. Additional capacitance values and cell sizes have been added to its already extensive supercapacitor platforms, the DGH 2.7 volt and DSF 3.0-volt series. The company’s product line now ranges from board-mountable coin cell types to radial form factors […]
Super-caps cover 0.5 to 600-F range at up to 3.0 V
The DGH 2.7-V and DSF 3.0-V series supercapacitors (aka EDLCs or ultracapacitors) are used to supplement rechargeable batteries or as replacements for batteries in a diverse range of applications. These new components add powerful options for engineers. According to Brendan Andrews, Cornell Dubilier Business Unit Manager, “Our technology is used in a wide variety of […]
Flexible wire-like supercapacitors can be built into power cords
Capacitech Energy’s Cable-Based Capacitor (CBC) technology is a flexible supercapacitor that stores energy in a wire-like form factor designed to be built inside of power cords. It can also be used to offset capacitors from the circuit board to the wiring infrastructure to reduce the size of electronics. Cabled-Based Capacitors can be connected in series […]
