How to remove a capacitor with its legs cut off
How to Desolder Electronic Components From Circuit Boards
This trick works the best for through-hole components that are mounted flush with the PCB, especially electrolytic capacitors. After adding a glob of solder as explained in the previous step, I melt the solder on one lead of the capacitor, and pull it out, as much as I can (which is normally about half way).
Replacing Through Hole Electrolytic Capacitors
2. Desolder both legs of the capacitor, then pull the capacitor out of the circuit board.

Replacing Through Hole Electrolytic Capacitors
1. By Look/Feel: Look for a bulged top on the capacitor. You may also feel that the vent has burst. One way to confirm suspicion of a bulged capacitor is to place a ruler on top of the capacitor with the edge touching the top. If the ruler will not stay flat, the capacitor
How to remove capacitors that are glued down?
I find it very difficult to remove the solder between the lead and the pad where the lead is bent at a 90 degree angle. Then when I go to wiggle on the cap gently to remove the cap, the glue that hold it down forces me to wiggle a little harder and the added resistance of the glue make it hard to tell if there is still some solder under the lead.
How to Discharge a Capacitor? Using Bleeder Resistor, …
If we remove or disconnect the power supply, the capacitor can supply its stored charge into the circuit. An important point about capacitors is that if a fully charged capacitor is not discharged in the circuit can hold the charge even after we remove the main power supply.
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

How to Remove a Capacitor Soldered to a Circuit Board
With the right tools and technique, you can remove a capacitor soldered to a circuit board. Instructions. 1 Plug in a soldering iron and rest it in its cradle, allowing it to heat up for at least 15 minutes. 2 Discharge the capacitors fully if they are high voltage, using a capacitor discharge tool. Normal voltage capacitors do not need to be ...
