BACKGROUND:

Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.

Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.

If you would like to know more about Ee values, please take a look HERE

These electrolytic capacitors are NEW, old stock

It is IMPORTANT to read my information page about both new AND old stock electrolytic capacitors ... please go HERE

SEMCO (Samsung Electro Mechanics) is a subsidiary of Samsung Electronics and began operations in 1973, known for their high quality components.

Like so many "forums" online, I have read some absolute "dribble" regarding electronic component manufacturers from those who appear to have no engineering or technical background at all (a bit like the Twitter of the electronic discussion groups)

ALL of the electro's I am clearing out of our workshops have served us well over the years, it is NOT just the manufacturer that is important - storage conditions, circuit function & design and so many other criteria are also very important for the reliability of any electronic component. Take a high quality capacitor such as an EPCOS, put it in a badly designed circuit and it will "fail" just like any other capacitor.
