Snap-in Aluminium Electrolytic Capacitors CD294

Snap-in electrolytic capacitor has the very high residual voltage after instantaneous short circuit, the usual explanation is that the dielectric absorption.If medium absorbing really so big, the influence of aluminum electrolytic capacitor frequency characteristic must be very poor, now even better than the real use of aluminum electrolytic capacitor is much worse, after all, low impedance frequency characteristics of the Snap-in electrolytic capacitor has done very well, and the latest polymer aluminum electrolytic capacitor frequency characteristic and even closer to the ceramic capacitor.Therefore, it can be said that aluminum electrolytic capacitor residual voltage is not generated by the dielectric absorption of p is another reason.So what reason be?The author thinks that is of special structure of aluminum electrolytic capacitor electrodes, which ^ so much residual voltage.
