Panasonic Capacitor 1000uf, 200V, failure concern

Former Member
Former Member over 11 years ago

Hi,

 

I am at a manufacturer that has experienced failures on the rectifier board with the capacitor venting or bulging.  There are three issues.  Is the issue a likely failure, Is this  real or fake panasonic part,  have other failures been reported ?

1.  We found the damaged part is a 1000 uf, 200 volt, capacitor part EETED2D102CAEETED2D102CA with a date code of 0921 (M).  Our analysis was that the capacitor has corrosion on the leads which causes the capacitor to fail then the imbalanced capacitors on the rectifier board causes a voltage spike that ruins the electronics.  Is it possible or a likely root cause to have corrosion on a lead ?

 

2.  I attached a photo.  Is the 0921 (M) code a real panasonic part date code and if so what does it mean.  We are finding other panasonic 1000uf, 200V capacitors that are slightly different in height and diameter and plastic cover print font.

 

3.  Are there any other field reports of problems on this capacitor.

 

Thanks

    Dear friend...just add a zener diode before giving connections to positive of capacitors.... Keep me posted ...
