Kyocera AVX has announced a range of high-capacity supercapcitor banks with low leakage.

“SCM Series supercapacitor modules are rated for operating temperatures from -40°C to +65°C and lifetimes that extend to millions of cycles,” according to the company. “They are also lead-free compatible, RoHS compliant, and compliant with the UL 810A standard for electrochemical capacitors.”

Initially there are five versions:

All capacitances are +30%, -10%.

Picking the 16V 58F SCMA63K586SPPB2 as an example, maximum operating current is 21.1A at 15°C, although peak up to 249A can be handled. Capacity is 2.07Wh and it weighs 680g.

Lifetime if cycled from rated voltage to half voltage and back is 500,000 cycles at +25°C – to a 30% or less capacitance loss.

IEC 60068-2-27, 29 / IEC 60068-2-6 vibration resistance is claimed to the same capacitance change.

Active cell balancing is supported, said the company.

Applications are foreseen with batteries or alone in uninterruptable power supplies, micro-grid storage, wind turbine pitch control, energy harvesting and regenerative energy capture.
