A new series of higher-voltage and high-energy-density supercapacitors, called DSF Supercapacitors, offer a notable jump in voltage rating over typical supercapacitors to 3.0 WVdc for a single component and 6.0 WVdc for a dual-pack device. This higher voltage spec results in greater energy densities, which in turn saves space and may reduce the number of […]
Metal terminal-type MLCCs handles high voltages
Murata Electronics announced the availability of two new metal terminal type multilayer ceramic capacitor (MLCC) series with temperature compensating U2J characteristics. The KCM line for automotive applications delivers low loss and excellent stability performance in high temperature, high voltages, and high frequencies. Similarly, the KRM was developed for general-purpose functions, with certain models rated at […]
Power capacitors handle ac filtering in three-phase delta connections
TDK Corporation presents two new series of EPCOS power capacitors for AC filtering in three-phase delta connection applications.

High-energy-storage, pulse-discharge capacitors handle repetitive high-energy/high-voltage charge/discharge apps
A major product expansion of standard and custom high energy storage, pulse-discharge capacitors is designed for handling applications requiring repetitive high energy and high voltage charge/discharge cycles. The capacitor technology is based on a film-dielectric with self-healing metalized or high-current discrete-foil electrodes, depending upon application requirements. There are both dry and oil-impregnated types, offered with […]
Tantalum polymer capacitors target high-capacitance, high-voltage apps
KEMET continues to develop and design solutions for alternative energy, industrial/lighting, medical, defense and aerospace, and telecommunications applications with the new Tantalum Stack Polymer (TSP) O 7360-43 and the 82uF/75V rated voltage extension in Polymer Hermetically Sealed. The TSP series is designed to provide the highest capacitance/voltage (CV) ratings in surface mount device (SMD) capacitors […]
Supercaps provide 600 F at 5.5 WVdc
CDE’s Illinois Capacitor brand DGH Series of supercapacitors has been its most popular to date, with a winning combination of low ESR and low cost. Now, the line has been expanded, with capacitance values up to 600 Farads. The DGH Series includes 24 different value/voltage combinations, ranging in capacitance from 0.5F (Farad) to 600F, with voltage ratings from 2.7 […]
Capacitor assemblies excel at power supply filtering
Knowles Precision Devices, a division of Knowles Corporation, recently expanded its capacitor assembly offering with the release of its new SV series of capacitor assemblies for power supply filtering applications. The SV series is a vertically stacked ceramic capacitor, offering superior performance compared with aluminum or tantalum electrolytic capacitors, while also helping to reduce the overall circuit board […]
Richardson Electronics, Ltd. to offer power-dense ultracapacitors from LS Mtron
Richardson Electronics, Ltd. will now handle LS Mtron’s 3.0-V 3,400-F ultracapacitor, one of the highest power density storage cells in the industry. The 3.0-V 3,400-F ultracapacitor stores 4.2 Wh of energy in a 390 cm3 package making it an ideal solution for customers who want to take full advantage of an ultracapacitor’s almost limitless charge […]
Power film capacitors target dc-link and dc filter apps
KEMET announces three new series of metallized polypropylene dielectric film capacitors: C44U-M, C44P-R, and R75H. Constructed with an aluminum canister design, both the C44U-M and C44P-R power film series address the increasing demand for high-power conversion systems in green energy and industrial applications. These capacitors also support power conversion in energy storage systems, IGBT and […]
Energy dense, low-profile caps get 5,000-Hour ratings
Cornell Dubilier Electronics, Inc. (CDE) has made significant design tweaks to their THA and THAS Series Thinpack capacitors. The product updates raise the rated life to 5,000 hours, a 66% increase over the first-generation devices. The key strength of the series is still high-energy-density. The 85 °C THA Series Thinpack capacitors are only 8.2mm thick, and […]
