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
It is IMPORTANT to read my information page about both new AND old stock electrolytic capacitors ... please go HERE
SPRAGUE of course is synonymous with high quality American engineering, sadly in 1993 many of their capacitor product range was sold to Vishay
Ex workshop/spare parts stock but this electro was in the "NEW" box in error I believe, read my thoughts about this below in the section COSMETIC CONDITION
SPRAGUE - Aluminium Electrolytic Capacitor
Made in USA
Model: 36DX132F450CF2A
Value: 1300uF
Working Voltage: 450V DC
Screw terminals
DIMENSIONS:
Bright Blue external insulating plastic around the main metal body
Top side vent plug/hole (for safety)
145mm height x 64mm diameter
Weight: 600g
COSMETIC CONDITION:
USED Tested
CLEAN
Spade terminals are clean and complete with spring washer
As detailed above, this capacitor was in a box of NEW electro's but I am 100% sure this is NOT new product. Why? the most obvious thing to catch the eye is around the top rim, some of the insulating plastic is missing. This does not affect operation of the capacitor but a new cap should not look like that.
Next I saw the Grey/Black line which goes right around the capacitor and just below that line I can see where a metal clamp once was pressed against the plastic. This capacitor has at one time been sitting in a clamp for sure.
Physically there are no "bulges" or other Aluminium can deformities and the top safety valve has never "popped" it actually looks like this Sprague capacitor was a "salvage" job by one of the techs some time ago in the past.
TESTING:
Considering the age and the fact this capacitor has been in service once, I undertook a basic capacitance test. Note that I have NOT preformed the capacitor, just put it on the tester straight out of the box to see what readings I would get.
Measured at 1638uF ESR 0.89 Ohm
Being just 20% higher in measured value (without preforming) and the manufacturer's tolerance is +50%, this capacitor appears to be fine
The capacitor has now had the terminals shorted, then the capacitor completely wrapped in bubble-wrap and sealed within a plastic packet ready for a new owner
