Basic understanding of ceramic capacitor voltage ratings.
Now there''s a lot of wiggle room in capacitor ratings, like how many can fail outright / violently (electrolytic), or how much the dielectric loses capacitance at voltage, vs. over time at ≈0 V (ceramic). So when you compare voltage ratings of dissimilar capacitors, the voltage rating seems almost arbitrary.

What is a low-voltage dry-type alternating current (AC) power capacitor?
This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
How is rated voltage applied to a capacitor?
For this purpose, the rated voltage is applied to the capacitors via a series resistance of approxi-mately 100 for VR 100 V DC, or 1000 for VR >100 V DC, for a period of one hour. Subsequently, the capacitors are stored under no-voltage conditions for 12 to 48 hours at a tem-perature between 15 and 35 °C.
What is the international standard for aluminum electrolytic capacitors?
The international standard for aluminum electrolytic capacitors is IEC 60384-4. The sectional specification mentioned above is complemented by a set of detail specifications that applies to specific design types (e.g. electrolytic capacitors with axial wire leads).
How much tolerance should a capacitor have?
A minimized tolerance (±0.35 mm) of the overall length l1 of the capacitor (figure 16) avoids un-wanted mechanical forces on the terminals, especially when several capacitors are mounted be-tween heat sink and bus bar.
What is a general-purpose grade aluminum electrolytic capacitor?
Aluminum electrolytic capacitors for general applications are called "General-Purpose Grade" (GP) in IEC publications. The international standard for aluminum electrolytic capacitors is IEC 60384-4.
