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
Disc ceramic capacitor from some British valve equipment, nice 1000V variety
Disc Ceramic Capacitor
Z5U Series
Value: 0.02uF (103) 20nF
Voltage: 1000V DC
Tolerance: ± 20% (M)
Radial leads
Z5U's were general purpose capacitors, known to show wide variations in value due to environmental conditions and circuit design operating conditions. See my test results below ...
LABEL IDENTIFICATION ON THE BODY
(Company logo which looks like a flattened diamond shape - I do not recognise this company)
CM
.02M
Z5U
1KV
DIMENSIONS:
Body: 3mm thickness x 16mm diameter
Leads: 5mm Length x 0.5mm diameter tinned wire
COSMETIC CONDITION:
USED
CLEAN
Leads are shiny and ready to be made use of once again
TESTING:
Wherever possible I like to test used components, these have been tested and the capacitance values are:
15.65nF
16.24nF
17.03nF
18.39nF
18.59nF
18.73nF
All are reading on the low side of the nominal value, with all but one within the 20% tolerance band and the 15.65nF is only just outside this band - nice!
*** Where the photograph shows multiple components, this advertisement is for ONE capacitor only - not all that are shown ***
