Why do capacitors have crimped leads?

This will isolate the capacitor from forces that it would otherwise experience during vibration, board flexing/bending, thermal expansion/contraction, etc. By providing the crimped leads at the factory, the board house does not require a machine to add those in-house.

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'.

How to prevent a capacitor failure?

Such failures can be avoided with preventive maintenance action such as replacing the capacitor. For film capacitors, the typical failure mode is capacitance decrease due to self-healing, so it is possible to diagnose the life expectancy by understanding the capacitance change.

Is it possible to reduce capacitor failures to zero?

However, it is difficult to reduce capacitor failures to zero with the current level of technology. Therefore, this report explains troubleshooting (diagnosis of failures and appropriate measures) to ensure proper and safe use of capacitors.

What type of capacitor is most likely to fail?

Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.

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.
