Leaking Capacitor, or No?
The term "leaking capacitor" has absolutely *nothing* to do with gooey stuffs "leaking" out of the physical container that your cap is in. Oxidation on a leg has absolutely no direct correlation to whether or not a capacitor is "leaking" or not. Now sometimes goo does come out but the technical jargon to reference this officially is "letting

Capacitors usually leak by bulging at the top, but can sometimes leak out the bottom. However, the electrolyte is pretty thin and will make a small puddle or show an obvious runoff if the device isn''t perfectly level. In some higher
ECU Capacitors
I can''t remember the name of the capacitors but they were brown in colour. So has any one in the club had similar problems and found them extremely difficult to solve, if so it might be worth while removing the top of the ECU and checking if the said capacitors are leaking and replacements are fairly cheap and could stop the vehicle being scrapped.

Telltale signs of failing electrolytic capacitors.
The effect increases the effective area by a large factor. Moreover, a ''wet'' electrolytic capacitor is an electrolysis cell in series with a capacitor. So, in the case of very powerful current surges, a large amount of ions migrate to both electrodes causing temperature rise, which can lead to capacitor failure.
6 FAQs about [Capacitors are leaking]
Do capacitors leak a lot of current?
I just found out that some capacitors hardly leak whereas other types of capacitors leak a lot of current through the dielectric. I’ve looked at Wikipedia and found several links (Leakage and Capacitor plague) which does not really described the current leakage (to the best of my understanding).
What is a leaking capacitor?
A leaking capacitor is a capacitor that loses its internal contents, such as electrolyte fluid or oil, due to damage or deterioration. This leakage often occurs in electrolytic capacitors, which are typically filled with a liquid electrolyte. Over time, this fluid can leak out due to factors such as heat, aging, or electrical stress.
Why do electrolytic capacitors leak more?
So, to get back to your question: even though it may seem like it, by far the most important reason that electrolytic capacitors seem to leak more is that they simply have more capacitance and, by association, larger surface areas and thinner insulators which both contribute to higher leakage.
How do you know if a capacitor is leaking?
Visible Leakage: The most obvious sign is the presence of leaked electrolyte fluid or oil around the capacitor. Bulging or Swelling: A bulging capacitor is a common sign of internal pressure buildup due to leaking electrolyte or gas. Discoloration: Leaking capacitors often show signs of discoloration around the body or leads.
Should you use a low leakage capacitor?
Consider Using Low Leakage Capacitors: If you’re dealing with high-performance systems, consider switching to low leakage capacitors. These types of capacitors, such as low leakage ceramic capacitors or low leakage tantalum capacitors, offer better resistance to leakage current and ensure longer lifespan.
Do ceramic capacitors leak?
Ceramic Capacitors: Although less common, ceramic capacitors can also experience leakage, especially if they are subjected to excessive voltage or heat. Ceramic capacitor leakage current can sometimes be a concern in high-performance applications.
