It''s to space the capacitor up off the board so that undue stress is not placed on the ends of the capacitor (for example, if the lead spacing in the board holes is not exactly the same as the lead spacing on that particular capacitor, or if the thermal coefficient of expansion is different from that of the PCB).
The hydrogen escapes by passing through the capacitor''s rubber seal. Sealing. The capacitor element is sealed into a can. While most cans are aluminum, phenolic cans are often used for motor-start capacitors. In order to release the hydrogen the seal is not hermetic and it is usually a pressure closure made by rolling the can edge into a
• Wave soldering (for THT devices) 4.1.1 Bending leads. In all processes, it is important to avoid straining the package and particularly the area where the leads enter the encapsulating resin. If the package/lead interface is strained, the resistance to humidity and thermal stress is compromised, affecting device reliability. 4.1.2 Insertion

If we start at the usual 0°, a sine wave''s value is low but its current - the slope - is the highest it will get. Inductors don''t like rapidly changing things, but capacitors do, so the capacitor is the one that reacts the most. The current flows at a max, then the

$begingroup$ @perilbrain, If the cap is literally placed across an AC source then (Rate of change in sinusoidal voltage)/(Rate of discharge) ~= 1 since the capacitor''s voltage will track the input. In general the relationship I see between the supply voltage frequency is something that itself actually changes with time. You will at first be charging the capacitor until

The capacitor element is sealed into a can. While most cans are aluminum, phenolic cans are often used for motor-start capacitors. In order to release the hydrogen the seal is not hermetic and it is usually a pressure closure made by rolling the can edge into a rubber gasket, a rubber end-plug or into rubber laminated to a phenolic board.
