“With low ESR and robust ripple current ratings, they will outperform surface mount electrolytics of greater size,” claimed the company. They “also provide longer life, greater stability with temperature changes, and lower ESR at higher frequencies than electrolytics. Compared to tantalum capacitors of similar size, they are lower in cost”.
Capacitance now ranges up to 470µF (from 6.8µF) and the maximum working voltage is 35Vdc (from 2Vdc). Surge rating is 1.25x the working voltage at +85°C.
Operation is over -55 to 105°C, and life is 2,000 hours at 105°C with full-rated voltage applied.
Two tolerance bands are available: ±20% (M), -35% +10% (Y)
Example parts are:
Cornell expects applications in dc-dc converters and inverters, as well as decoupling and suppressing noise in environmental controls, LED lighting, instrumentation, office automation and medical equipment.
