Try to use a higher impedance resistor so that the capacitor is charged slowly. This will prevent the capacitor from charging too fast and sustaining damage.

Compared to other capacitor technologies, EDLCs (Electric Double Layer Capacitor) are outstanding for their very high charge storage capacity and very low equivalent series
A power supply (or battery for portable equipment) is used to charge the capacitor to a set voltage. There are two ways of charging a capacitor: using a fixed voltage power supply or using a supply that is capable of providing a constant current. Lasers are now commonly used in cosmetic surgery equipment, material cutting and additive
Monitoring of parameters like voltage, current, and temperature during charging is recommended. With their high power density, fast charging capability, and long cycle life,
Capacitors used in decoupling circuits are called decoupling capacitors. They are employed in the DC voltage supply circuits of multi-stage amplifiers to eliminate harmful low-frequency coupling between amplifier stages. 4. High-frequency Damping: Capacitors used in high-frequency damping circuits are called high-frequency damping capacitors

You didn''t say exactly what voltage you wanted to charge the capacitor to, but generally speaking you shouldn''t go all the way up to the rating if you want the device to be reliable. For this I need a high voltage supply. You can get a high voltage module from distributors like Digikey or Mouser.
Capacitors are an essential part of electronic circuits that can store electrical energy and charge. They are widely used in electronics, power systems, and other applications due to their unique properties. These components are simple in construction and can be found in various shapes and sizes, making them versatile components.

This article addresses the challenges related to charging these large capacitors, and shows power system designers how to evaluate and select the best system configuration for backup energy
Super capacitors can be used in solar power applications, battery back-up applications, battery applications, flash-light applications, etc. Aside from the fact that the super capacitor can be charged very quickly due to their low internal resistance, which is known as ESR, but they can just as quickly be discharged. Batteries contain harmful
Modern capacitors can be classified according to the characteristics and properties of their insulating dielectric: Low Loss, High Stability such as Mica, Low-K Ceramic, Polystyrene. Medium Loss, Medium Stability such as Paper, Plastic Film, High-K Ceramic. Polarised Capacitors such as Electrolytics, Tantalums.
This will "let" high frequency noise go to ground instead of through the IC. If you have a part switching on and off quickly, it wants to grab instantaneous current from the power line (high frequency). The power line will dip, which looks like a high frequency blip on the power line. The capacitor stops this by "giving" some if its stored
Capacitor is a charge reservoir. Switched-mode power supplies need to charge it first. Too large capacitors might make the internal power supply loop go unstable, which would create large voltage deviations across the capacitor and potentially burn it due to too large capacitor heating caused by its non-zero parasitic resistance called "ESR".
However, the charge is returned to the power supply when one is positive, and the other is negative. No power is consumed because the charge is the same size as the discharge. There is as much power curve above the zero line as below it. The average power in a purely capacitive circuit is zero. Takeaways of Capacitors in AC Circuits
You can use the following two formulas to work out the resistance and power rating they''d need to be: P = I V. R = V / I. So if you want to use the 4v PSU and it has a 2A rating, the resistor you should use is: R = 4v / 2A = 2 ohms (or higher) And the resistor''s power rating should be: P = 4v x 2A = 8W (or higher).

However, several car audio systems use ceramic capacitors. Though capacitors take less time to charge and store less energy when compared to batteries, you can charge them to a maximum voltage level and get the best out of them.

Electrolytic capacitors are available for large amounts of charge (capacity) and for high voltages, but they are slow. So, you find them closer to the main power source and slower high-power circuits. They are not good for the microcontroller chip itself. There ceramic capacitors are used. Sometimes even multiple with different values.
Compared to other capacitor technologies, EDLCs (Electric Double Layer Capacitor) are outstanding for their very high charge storage capacity and very low equivalent series resistance (ESR). Their high cycle life, low charging time and their large power output make them the ideal choice for many electric power applications.

Calculation: a capacitor with a capacitance of 50 F is recommended. For constant voltage charging it is recommended to use a protective resistor in series with the EDLC. It may be necessary to restrict the current with a protective resistor RP to a specific value Imax.
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
Using an off-the-shelf constant voltage power supply to charge a capacitor can cause problems. When the power supply is initially connected to the capacitor, it will try to deliver its maximum allowable current and probably go into an overload condition.
Capacitor charging involves the process of storing electrical energy in a capacitor. When a capacitor is connected to a power source, such as a battery or a power supply, current flows into the capacitor, causing it to charge. The charging process is governed by the relationship between voltage, current, and capacitance.
1) You must never charge past the capacitor voltage rating. If you have a 2.5v super capacitor, you must NEVER charge it at a higher voltage. If you do, you risk damaging the integrity of the capacitor, or worse, an explosion. Personally, I never charge past 80-90% of the rated charge.
I have a semi-serious hobby project with a couple of friends where we need to charge a pulse operated capacitor rated to around 4kV with 1500nF capacitance. You didn't say exactly what voltage you wanted to charge the capacitor to, but generally speaking you shouldn't go all the way up to the rating if you want the device to be reliable.
