6 FAQs about [How to repair capacitor damage]

What happens if a capacitor fails?

When current repeatedly flows into a defective part due to overvoltage or dielectric degradation, the capacitor continues to self-heal and loses capacitance. Generally, a capacitor is considered to have failed when its capacitance drops by 3% or more compared to its initial value. The probability that a failure will occur is called 'failure rate'.

What to do if a capacitor fails?

Even if the appearance of the failed capacitor is not abnormal, care must be taken when handling the capacitor. In particular, take care to avoid electric shock *1 due to residual charge on the capacitor, contact of electrolytic solution *2 with the skin or eyes, and inhalation of electrolytic solution vapors.

What happens if a capacitor is ruptured?

The pressure-relief vent *9 of an aluminum electrolytic capacitor used for smoothing the power circuit was ruptured and a capacitor started smoking. When the internal pressure of the capacitor rises, the pressure valve opens and electrolyte (gas) is released.

What happens if a capacitor leaks?

Aluminum electrolytic capacitors and electric double-layer capacitors (EDLC) *7 use a conductive liquid called electrolyte. If this electrolyte leaks out of the capacitor housing or sealing area, it can cause the capacitor to lose its function, short circuit the circuit board, or have a negative effect on surrounding components.

What happens if a capacitor is open?

For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is directly applied to the circuit, which may cause semiconductors and other components to fail. *4 It's called ripple voltage.
