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
This electrolytic capacitor is NEW, old stock
It is IMPORTANT to read my information page about both new AND old stock electrolytic capacitors ... please go HERE
Joe Master aluminium electrolytics were intended for general purpose and could often be found in older Asian produced audio equipment.
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 design functional requirements and so many other criteria are also very important to determine the suitability and reliability of any electronic component in circuit. Take a high quality capacitor such as an EPCOS, put it in a badly designed circuit or expect it to perform functions that it simply was not designed to undertake and it will "fail" just like any other capacitor.
I seem to recall that although these caps have a very English sounding name, they were in fact manufactured in Asia - specifically I think it was Taiwan.
It was a long time ago that I got these and I cannot seem to locate any current manufacturer using the same trade name so I guess they have faded into the mists of time ...
JOE MASTER - Aluminium Electrolytic Capacitor (1)
Made in Taiwan (??)
Value: 1000uF 10V
Termination: Axial leads
Dimensions: 20.75mm L x 13.2mm Diameter
Lead length 25~30mm x 0.55mm diameter tinned wire
TESTING:
I had some spare time so I took a "look" at these capacitors in more detail ...
As I only have a small number, every cap has been tested
Average Vloss around 2.4%
Average ESR around 0.8 R
Most measured in the region of 1400uF, a couple closer to 1000uF
Overall, these remain "acceptable" general purpose caps although best not suited for use in power supplies although this is not likely in any case due to the low working voltage of just 10V DC.
COSMETIC CONDITION:
Very good condition
Leads remain very serviceable with just a hint of light dullness due to oxidisation.
Stored in the original sealed plastic packet
