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.

Highlights

- Rapid charge

- Circuit board mountable

- Standard snap-In design
