Capacitor Failure
Capacitor Failure
Hello,
Can someone explain me the reasons for the failure or explosion of the capacitor??
Can input voltage dip, be the cause for the explosion of capacitor??

Re: Capacitor Failure
Could be lots of reasons... faulty cap... power surge ... reverse voltage(if it's electrolitic) ... etc ...etc...
It is not because of less voltage... there is likely to be (if its not the cap) a short.
Tar&stuff.

Re: Capacitor Failure
Helpful links capacitor's failure depends on some reason
Several things cause the most failures:
1. The manufacturer used a cheap capacitor or one that is not rated properly for the job.
2. It is in an environment that is too hot.
3. Multiple powerline surges have destroyed it.
4.It is important that the capacitors used on computer motherboards or other devices have Low Equivalent Series Resistance. The most typical failure mode of a capacitor is that the Equivalent Series Resistance has become quite high and therefore it cannot be considered to be a Low Equivalent Series Resistance capacitor anymore.
if you want to calculate capacitor then use those powerful electronic tool.

after measurements u can easily identify which one best for u(capacitor) if u need more information regarding this issue then feel free ask me. am looking for your reply.
Thanks
