CDHC Datasheet, PDF (1/3 Pages) Cornell Dubilier Electronics – Type CDHC Snap-In Hybrid Carboncap Power Ultracapacitors

Type CDHC Snap-In Hybrid Carboncap Power Ultracapacitors
Large Cylindrical Type
The snap mount hybrid ultracapacitors are designed for board
mountable power backup applications. The best applications
for these type of ultracapacitors have low power, low energy,
and low charge/discharge cycle rates. The main feature of these
ultracapacitors is the ability to be rapidly charged preferably
followed by a slow discharge. Applications include solar lighting,
LED lighting, and portable devices.
