What does a high capacitance capacitor mean?
Higher capacitance means more energy storage. Voltage Rating: Every capacitor has a maximum voltage it can handle before breaking down, known as the voltage rating. Exceeding this rating can cause the capacitor to fail, sometimes catastrophically. Equivalent Series Resistance (ESR): This represents the capacitor's internal resistance.

So what is electrolytic capacitor reconditioning (also known as reforming)? Basically, it is applying the maximum rated voltage on capacitor for a period of time. This is done in order to rejuvenate the electrolyte and/or aluminum oxide layer inside the capacitor.
FAQs about How to replace the self-healing capacitor
Can a self-healing process destroy a capacitor?
Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.
How does an aluminum electrolytic capacitor work?
As you can see, the capacitor gets better at retaining charge with each iteration. The leaky areas inside an aluminum electrolytic capacitor are converted to aluminum oxide (an electrical insulator) when a charge is applied. The capacitor is repairing itself. The rate of improvement tapers off as the quantity and severity of leaks decline.
Do electrolytic capacitors need to be re-formed?
It's not a question of "if it needs re-forming it's not good", but rather a question of extending the life of modern electrolytic capacitors to behave within spec for 20+ years after their expiration date. If you re-form your caps, they will last forever. If you don't you will be throwing them out and buying new ones every few years.
How do you recondition a capacitor?
Capacitor should be reconditioned by applying rated voltage in series with a 1000 Ω, current limiting resistor for a time period of 30 minutes. I also saw some places online suggest to reform caps for 5 minutes (minimum) plus 1 minute for every month the cap was stored.
Why should you choose a film capacitor with controlled self-healing?
Catastrophic failures and associated explosions or fires are unacceptable. Just as importantly, service lifetime and predictability for optimizing up-time are critical to the product's success. Film capacitors with controlled self-healing are the ideal solution to these challenges and can be obtained in various sizes and technical specifications.
What happens if a capacitor is used without reconditioning?
Long Term Storage Leakage current of a capacitor increases with long storage times. The aluminium oxide film deteriorates as a function of temperature and time. If used without reconditioning, an abnormally high current will be required to restore the oxide film. This current surge could cause the circuit or the capacitor to fail.
