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
NEW OLD stock from my workshop yonks ago, back in the days of valves with +300V B rails
It is a long time ago but I think I had these for some valve based RF projects, the values are very small
It is time for me to clear out EVERYTHING I have amassed over the years, both personal interest and professionally, so these caps are looking for a "purpose in life!"
MANUFACTURER UNIDENTIFIED - Disc Ceramic Capacitor
Olive Green Series
Value: .0033pF (3300pF)
These are all reading high, see my measurements below ...
Voltage: 630V DC
Temperature Coefficient: not stated
Tolerance: M (+/-20%)
Radial leads
IDENTIFICATION ON THE BODY
.0033
630V
M
No other markings or colour coding is used on the body
DIMENSIONS:
Body: 2.45mm thickness x 10.7mm diameter
Leads: 29mm Length x 0.55mm diameter tinned wire
COSMETIC CONDITION:
NEW
OLD stock
CLEAN
Leads have a 'dull shine' meaning that some oxidisation has occurred but they will still remain fine for soldering, even without a "brush up"
TESTING:
Wherever possible I like to test OLD components, even they are new
Measurement 'band' results:
Lowest: 2666pF
Highest: 3082pF
The majority sit in the region 2800 ~ 2990pF
These measurements indicate that all of these capacitors measure on the low side of the stated value. As the tolerance is specified as 20% (M), all of these capacitors are well within the expected values, on the low side.
*** Where the photograph shows multiple capacitors, this advertisement price is for ONE capacitor only - not all that are shown ***
