Electrolytic Capacitors Is Our Good Friend?
I got an email that stated “Electrolytic capacitors is our good friend”. I was curious as why the sender sent such a sentence then he continued to reason to me behind the meaning. He mentioned this because “electrolytic capacitors has helped him to earned lots of money because lots of electronic equipment broke down was caused by bad electrolytic capacitors.”
Yes it is true especially nowadays lots of electronic equipment comes with cheap electrolytic capacitors and easily turn bad when exposed to too much stress, heat and etc. There was one brand of a 15″ HP LCD Monitor where 9 out of 10 problems was caused by bad electrolytic capacitors. He further mentioned in his email that ” although there are lots of bad electrolytic capacitors in circuit board, if one does not have the ESR meter, the electronic repairer will have a hard time finding it out!”
That was also true of what he had said. If we as an electronic repairer and does not own any ESR meter, we will definitely have a hard time to locate problems in electrolytic capacitors. So is Electrolytic Capacitor your good friend?
