HISTORY:
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 BRAND 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 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.
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: 470uF 63V
Termination: Axial leads
Dimensions: 30.75mm L x 13.25mm Diameter
Lead length 35mm x 0.55mm diameter tinned wire
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 packs and I am fine with supplying any quantity from just one cap up to the full available quantity showing on this page (with the resulting substantial quantity discounts automatically applied)
TESTING:
Being old stock, I decided to "batch test" some of these capacitors ....
Random batch of 5 capacitors tested
Vloss % range: 1.4 1.4 1.4 1.6 1.4
Measured values: 488 469 478 471 475
ESR range: 0.92 0.94 0.90 0.88 0.89
*** Where the photograph shows multiple components, this advertisement is for ONE capacitor only - not all that are shown! ***
