Type CDLC Snap-In, Carboncap Power Ultracapacitors
Large Cylindrical Type
These low RC time constant, organic electrolyte, large cell
ultracapacitors easily handle more than a half million duty cycles and
solder readily onto circuit boards using snap-in terminals. They are
especially suited for back-up and pulse power applications such as
grid stabilization and wind turbine pitch control. Snap mount cells
are ideal for portable devices, hybrid energy storage, and emergency
lighting.
