Supercapacitor balancing kit

Kemet has introduced a supercapacitor balancing development kit for its S301 family of 60mm diameter capacitors.

Used in series, supercapacitors need electronics to ensure no capacitor goes over the rated voltage as the string approaches full charge – 2.7V in this case, see below.

The kit includes two-stage active…
