The PBD PowerBurst ultracapacitor modules perform as a drop-in replacement for Maxwell Technologies' discontinued BC BPAK0052/0058 and BC BMOD0052/0058 ultracapacitor series. The multi-cell modules employ Maxwell’s radial 350F, 2.7V cells to facilitate a 58F module with a ESR of 22.4 m? and 16.2V working voltage. Apps include UPS, telecommunications, and other industrial electronics. Additionally, the modules can withstand over 500,000 cycles or 10 years of life under specified operating conditions. In quantities of five or more, unit pricing for PowerBurst PBD shrink-wrapped ultracapacitor modules is $204. TECATE INDUSTRIES, San Diego, CA. (619) 398-9750.
