Electrolytic Capacitor Testing and Replacement Cheat-sheet

Here are some fundamental rules for replacing electrolytic capacitors in circuit boards. Replace with exact type if available. Replace with capacitor that has the same capacitance (uF – microfarad) as the original. Replace with capacitor that has the same voltage rating or higher. Use higher temperature capacitors when possible (105c).

Capacitor Reforming

If there are any visible signs of failure of a capacitor (leaks, etc) you should replace it; reforming will not fix those problems. Reforming is a preventative measure to potentially reverse natural deterioration in the capacitor.

6 FAQs about [What methods can replace capacitors]

How do you replace a capacitor?

Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted. Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example.

How to replace electrolytic capacitor?

Is it necessary to replace a capacitor with an exact replacement?

No, it is not necessary to replace a capacitor with an exact replacement. In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw.

How do you put a capacitor on a circuit board?

For larger capacitors use thicker wire (lower gauge) or put multiple cat 5 strands in parallel to each lead. Find and mark all the capacitor leads on the back side of the circuit with + and -. Make jumpers that will go from the back side of the board to the front of the board where the new capacitor will be placed.

How do you replace capacitor jumpers?

Keep the jumpers short as possible and twisted together, it will reduce interference. Strip the ends of the jumpers, solder them to the old capacitor leads and to the new capacitor leads. Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted.

Can you replace a capacitor with a higher value?

In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw. Can I use a 25V capacitor instead of 35v?
