Tecate's PowerBurst Type PC5 ultracapacitor – offered under a license agreement with Maxwell Technologies – is engineered to provide extended power availability during dips, sags, and outages in the main power sources as well as to relieve batteries of burst power functions. The RoHS-compliant part's flat prismatic cell design notably incorporates stainless steel, hermetically sealed cells. This construction boasts a low profile (5.1 mm max.) making it suitable for space constrained applications. The low ESR (Equivalent Series Resistance) PC5 ultracapacitor is capable of accepting charges at the identical rate of discharge, and features accessible terminals and an electrostatic storage capability to facilitate over 500,000 duty cycles and a 10-year life capability. Tecate's PowerBurst Type PC5 ultracapacitor is commonly specified for providing, holding up, or bridging power until the back-up power source "kicks in" when the primary power source fails. Its back-up power capabilities make it appropriate for soft shutdown, "last gasp" notification, battery swaps, and memory retention. Standard parts feature a voltage of 2.5 VDC, capacitance of 4.0 F, and an extended temperature range of from -40ºC to +70ºC. Capacitance tolerance is +/-20 percent.
