Universal Motorcycle CDI Circuit [Capacitor Discharge Ignition]
The output is coupled to the ignition could that delivers the high voltage pulse to the spark plug. Then, the electrical energy gets stored in Capacitor C1 through D3. Once there is a pulse at the input, the thyristor gets activated into conduction. This action pulls C1 to ground where it can discharge to the ignition coil. PCB Design

high current
A too-fast discharge will indeed damage a capacitor, but a not-fast-enough one will impact your functionality. (I am assuming that you want to have a short but powerful current burst through your coil) Capacitors, like all components, can not withstand too high current (or discharge rate, both are the same in a capacitor).

Design Guidelines for Flyback Converter Using HFC0400 …
These X capacitors may present a safety hazard because they can store unsafe levels of high-voltage energy for long period of time after the AC is disconnected. To meet safety standards, the traditional method is placing resistors in parallel with the X capacitor (if the X-cap is larger than 0.1μF) to discharge the X-cap in a specified time.
CDI = Capacitor discharge ignition
In a CDI system, the system charges a capacitor by default, and during the ignition point the system stops charging the capacitor, allowing the capacitor to discharge its output to the final coil before reaching the spark plug. A typical CDI module may consist of a small transformer, a charging circuit, a triggering circuit and a main capacitor.
Aluminium Stud Welding Methods
Capacitor Discharge (CD) Stud Welding: Capacitors are charged to a predetermined setting on the power supply. When triggered, the stored energy is "discharged" and the burst of electricity creates the molten pool. The gun pushes the stud down into the molten pool. CD studs have a special tip on the end that is consumed during the weld.
Electrical Discharge Coil
When a signal is sent to the trigger_in pin of the Discharge Coil, the coil shocks the area around itself. By default it has a 5m radius, travels 25x further through walls, and has a duration of 0.2 seconds. Note: Some larger Creatures are immune to stun, extremely limiting the coil''s effect.

How To Select An MSD Capacitive Discharge Ignition System
The advantage of the capacitor is that it can discharge high voltages very quickly. When 500 volts is applied to the primary side of the coil, this saturates the primary side very quickly. Again, with a turns ratio of between 70 and 100:1 on a CD style coil, this high voltage on the primary side produces as much as 45,000 volts on the secondary ...

Working principles of inductors and capacitors | Electronics360
Capacitors store energy until they are connected into a circuit, at which point they discharge. An electric current is produced when electrons from the negatively charged plate travel across the circuit to the positively charged plate. The capacitor''s discharge rate is proportional to the product of its capacitance and the circuit''s resistance.
