High quality long life low ESR capacitors?

[carpenter]

An electrolytic capacitor is perhaps the most problematic component in today's electronics.
I want to ask what capacitors, manufacturers, series are considered to be of high quality?
I use Nippon LXZ or KZNm, there are certainly other good producers and maybe they have a better price / quality ratio
What capacitors do you recommend?

Hi,

if you go to your distributor´s internet site than you will find available capacitors form other manufacturers.
Look for "operating temperature" and expected lifetime in the datasheet.
Maybe there is a chart for this.

The major Japanese manufacturers, like Nichicon, Panasonic Industrial and the like are very reliable.

High quality long life low ESR capacitors?

It is an oxymoron. Compared to other electronic components, they have the poorest performance (life time being the key consideration).

The major problem is the electrolyte and ALL manufacturers closely guard their key secret. It is impossible to verify their claims independently.

It has been often been claimed that an overrated component (if your application demands 25V working voltage, use one with 65V) usually helps (appears reasonable).

Remember that internal corrosion can take place even when the product is not being used (in circuit; there is a shelf life).

Does word of mouth helps? Perhaps!

Today electrolytic capacitors are one of the fastest ageing electronic components. Design conservatively.

You can buy 10,000 hour 105 deg C electrolytics that last for a very long time at rated current - they just cost more ...
