The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
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. A case with an extra groove near the base for ring-clamp mounting (recommended accessory B44030A0165B ... A0190B).
Generally, the materials used for aluminum electrolytic capacitors must meet strict purity re-quirements, and those used for producing LL grade capacitors must be specially selected. The de-sign effort required for such capacitors affects both the case size and the price.
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.
It depends on the capacitor design and is stated in the re-spective IEC climatic category. If this limit is exceeded the capacitor may fail prematurely. For some type series, however, operation at temperatures above the upper category temperature is permissible for short periods of time. Details are given in the individual data sheets.
Specific mounting conditions: For smaller lead spaces than 22.5 mm, the capacitor shall be mechanically fixed by the leads. For lead spaces ≥22.5 mm, the capacitor shall be fixed by the leads and the body must be properly clamped.

Capacitance is the amount of electrically charged carriers a capacitor can store per unit of volt-age. The rated capacitance CR of a capacitor is the value for which it is designed, and that is in-dicated on it. Capacitance is measured under standard conditions to IEC 60068-1:2013.

Even for capacitors for very high voltages, layer thicknesses of less than 1 μm are attained, thus enabling very small electrode spacings. This is an-other reason for the high volumetric efficiency achieved (e.g. in comparison to the minimum thick-ness of a paper dielectric, 6 to 8 μm).
