The role of electrolytic capacitors in switching power supplies are:
1. Blocking DC: The function is to prevent the passage of DC and allow the passage of AC.
2. Bypass (decoupling): Provide a low impedance path for some parallel components in the AC circuit.
3. Coupling: As a connection between two circuits, it allows AC signals to pass through and be transmitted to the next-level circuit.
4. Filtering: Change the rectified sawtooth wave into a smooth pulsating wave, close to DC.
5. Energy storage: store electrical energy and release it when necessary.
Relative Parameters:
Dielectric material: aluminum electrolytic.
Product shape: cylindrical.
Power characteristics: medium power.
Lead type: radial lead wire.
Allowable deviation: ±20%.
Installation method: direct insertion.
Lead description: long lead = positive "+"; short lead = negative "-".

Used two of the capacitors so far to fix a Vizio sound bar power board, and have had no issues. they worked great.

I ordered this trying to repair an original DMG Gameboy. This kit does not include the correct size capacitors for that repair. Still a good kit though!
