... Ripple current, less than 100mΩ equivalent series resistance (ESR), and temperature are major considerations when selecting input capacitors. The ripple current reflected from the input of the PTH12040W module is moderate to low. Therefore any good quality, computer-grade electrolytic capacitor, of either value suggested, will have adequate ripple current rating. ...
