personal projects I’ve really dug into some hybrid

caps from Vishay Intertechnology.

Lithium-Ion Capacitors (LiC)

LiCs typically use the same packaging as EDLCs

so can be easily mistaken; the biggest tell is their

rated voltage, usually 3.8V though I’ve seen some

4.0V (and heard of 4.2V). The capacitor nature

of these lets them handle more power (current)

than a battery of the same size, but with more

energy than an EDLC of the same size. They have

more limitations than capacitors, as they do have

a discharge cutoff that needs to be respected

for continued use. None of the datasheets I’ve

read have mentioned managing ...
