Capacitors Guide: Types, Uses and Choosing the Right One
A 180-µF, 450-V electrolytic capacitor from the TDK-EPCOS B43508 series has a ripple-current rating of about 3.5 A rms at 60 C, including frequency correction. To handle 80 A would require 23 ...
In various circuits intended for use with 230-250 V AC I''ve seen capacitors labelled as "400V" (Examples: 1, 2) When I look at Capacitor specifications, they often give separate AC and DC ratings. For example: X1 440 VAC 1000 VDC X2 350 VAC Y2 400V (but package confusingly marked "Y2 (330V~) X1 (440 V~) ..

4.6: Capacitors and Capacitance
Generally the remanent polarization of pristine Hf0.5Zr0.5O2 thin films increases after the wakeup performance at room temperature. However, the improved polarization has poor retention at other temperatures. Here we studied its temperature dependence of polarization retention after the wakeup at 450 K without invoking of dielectric breakdown. …
Despite this, electrolytic capacitors aren''t best suitable for snubber networks since snubbers have very high peak currents that would self-heat and damage an electrolytic capacitor. Worse yet, aluminium wet electrolytic capacitors have terrible reliability and conventional MnO2 tantalum capacitors are sensitivity to high power surges.
