When developing mission-critical space applications such as low Earth orbit (LEO) satellites or equipment designed for Mars missions, there are special considerations you must make if you will be operating your RF circuits in a vacuum. This is because when the pressure in the vacuum is below 10-2 Torr, a potentially catastrophic phenomenon in RF circuits called multipaction is possible.

Ceramic capacitors are leading miniaturization, downsizing and dominating the market share. The right charts are based on sales VALUE, but if we have these charts in sales VOLUME ceramic capacitors would occupy up to 80% of market share of all capacitors made, on the other hand more expensive tantalum capacitors would shrink its share in volume terms.

TI developed the circuit based on circuits already in use for Li-ion batteries. The integrated circuit bq33100 [1] provides more than the balancing of supercapacitor banks, being a single-chip solution that offers many features for charge control, monitoring, and protection of maximum of 5 series capacitors.
