Haven't you noticed recently that some (in fact many) types of relatively cheap electrolytic CAPS fail after no longer than a few months??.. Specially those of east asian origin...I start to become sick of returning repaired LCD/LED TVC's for the same symptoms and reasons: same failure of same caps in the SMPS area!! Very short lifetime...Even higher than required voltage / temperature rating doesn't help much!
The question I ask is: where does the real manufacturing deficiency or problem reside in their fabrication ? The chemical/dielectric procuct inside these capacitors or what, exactly?
The other quest is: What is your advice regarding the choice of good/better/ best longlife caps?
I'm ready to pay 10$ for just ONE 470 or 1000 micofarad/50 or 63v if I know that its life time is a garanteed "more than 5 or 10 years" period (in normal working conditions). I know It's worth it, very simply because my client will get full satisfaction and he/she may come back for repair but NOT for the SAME problem!
