Hi! Here is one application having need for extra good ripple push-down, thus the 1 Farad 5 Volt capacitor may stand for be ideal solution inspite even the price. But the circuit using this power Vcc will have a 8 MHz clk, and power supply givig this Vcc have the ripple 0,5 MHz; thus the cap must be fast enough even if surrounded with plentitude of ceramic paralleling caps.
Thus, I overlooked some dozen datasheets of different firms of supercaps - NO ANY word about speed, max frequency as only warranted ESR at 50 Hz and at 1000 Hz.
May someone advice me something to read about their habits at far higher frequencies??
