Electrochemical supercapacitors eliminate need for external balancing resistors

Myrtle Beach, SC — AVX Corporation, a leading manufacturer of passive components, announces significant advances made to its BestCap (Battery Energy Saving Technology Capacitor) series of electrochemical supercapacitors, resulting in the highest voltages available in the industry for low ESR pulse supercapacitors. Offering superior high power pulse characteristics due to this combination of high capacitance and ultra low ESR, the BestCap electrochemical double layer pulse products are now available in BZ05 and BZ06 cases, with an expanded capacitance/voltage range of 500mF/3.3V to 90mF/12V, with sub-100mOhm ESR and DCL in the range (5-40)A.

AVX's patented aqueous polymer chemistry makes the BestCap a fully RoHS-compliant, environment-friendly, non-hazardous device, with superior pulse performance over alternative organic technologies. The component's ultrathin construction offers designers high energy per volume.

“The BestCap series provides high capacitance, even with short pulse applications, and offers more efficient energy savings in battery circuits than conventional supercapacitors,” said Chris Reynolds, AVX product manager. “The polymer technology eliminates the need for external balancing resistors, while the low ESR results in a high current handling capability, making this an ideal solution for any portable or wireless devices requiring high power availability. The availability of high voltage ratings vastly expands the number of power management applications that can be addressed.”

The new BZ05 package targets pulse hold-up applications from server/ADSL to wireless/electromechanical AMR (automated meter reader), while the BZ06 is a special low-profile device for digital cameras and PCMCIA.

Pricing for BestCap starts at $3.25 in quantities of 10,000. For more information on AVX's BestCap technology, contact AVX Sales and Marketing at 801 17th Avenue South, Myrtle Beach, S.C. 29578; by calling 843-946-0414; by fax 843-626-5186; or on the web at www.avxcorp.com.
