Soviet capacitor, what are the specs : r/AskElectronics
Hey just a heads up - the electrolyte in these old capacitors is quite toxic, often containing PCBs. If you blow them up you may have to take some serious measures to clean up your house. Make sure they''re properly disposed of at a
Explaining Capacitors and the Different
Learn about the different types of capacitors and why you would use different compositions. since materials released during a failure can prove to be quite toxic.

Properties of aged oil impregnated paper power capacitor
The oil impregnated paper capacitor had been produced until 1982, and most capacitors are operated still. Because the operated years pass 20 years or more, and the troubles occurred in some operated capacitors, the research of the deterioration mechanism and development of diagnosing method for the operated capacitor have been continued. In this paper, the

What can replace .005mF waxed paper capacitors from 1949?
I have found film capacitors on the Digikey site for all but one value - .005mF. Inside this radio are five of them but of different voltages. One is 200 volts, two are 500 volts and two are 600 volts. Any suggestions on what to use for substitutes? If there are .005mF capacitors still available, and are 600 volts, that should cover all of them.

Wax Paper Capacitor Test
Wax-dipped capacitors dominated the defect pile while caps with plastic/epoxy/polymer cases age well. I believe this too. Bentonite suspended in water. Worked great, as non-toxic as you can get, and with a field of under 100V/cm would handily demonstrate the effect. Instead of 30,000V. Took some doing to convince the head of the department

Datasheet Audio Silver Mica Capacitor
After vacuum impregnation with a specially developed wax we have a solid non-resonant structure which is far superior to the more common (and cheaper!) ''Clamped'' mica construction Incineration of resin encapsulated mica capacitors can cause emission of toxic fumes. • Unsafe use Most failures are of a passive nature and do not
Replacing Tubular Wax Capacitors
It seems that the decision to replace the wax capacitors in any radio set depends upon how the set has been stored over the years. I have some sets that work great with all of their original caps in place (except for the electrolytics). I have other sets that would definitely benefit from a capacitor-ectomy.

Others are judged on merit - for instance a 100 nF wax capacitor shunting a 150 ohm cathode bias resistor in an IF amplifier would probably be left alone. During alignment, I might temporarily shunt it with another, just to check that it''s doing its job. Tone correction capacitors wired across the output transformer primary can also generally
Mechanically damaged aluminium electrolyte capacitor
$begingroup$ The electrolyte is not very toxic, but it will make you sick if you swallow enough of it. If you just touched a small amount of it you should have no reason to worry. At room temperature, there would not be much vapor. A capacitor that overheats in a live circuit will release some vapor. I have seen large capacitors overheat and

If it was a "wet" capacitor with a gel / liquid electrolyte, that was likely either ethylene glycol (aka "anti-freeze") or boric acid (think Borax laundry soap).
Can capacitor burst be dangerous?
If a capacitor explodes due to a revers voltage being applied, then toxic gases and corrosive chemicals can be expelled and if they are ingested or land on skin or clothing can produce
6 FAQs about [Is capacitor wax toxic ]
Are disc capacitors safe to use if overloaded?
Disc capacitors tend to crack open if overloaded-the polarity does not matter. Unless you overvoltage them or reverse voltage them or have a high current ripple in the DC power line beyond the capacitors rating they are safe to use. I have had them (electrolytic can capacitors) explode in my face due to being installed in reverse.

Can a capacitor kill you?
Some doesn't. If properly abused, that capacitor would make quite a bang and mess. It is unlikely that the bang would kill you even if you were a couple of feet away, but you can't rely on that, and it could certainly hurt you pretty severly. A serious injury like loosing one or both eyes isn't far fetched at all.
How do you know if a capacitor is wet?
If it was a "wet" capacitor with a gel / liquid electrolyte, that was likely either ethylene glycol (aka "anti-freeze") or boric acid (think Borax laundry soap). If it was a solid capacitor, the equivalent of an electrolyte was another film of manganese dioxide (MnO2). Wet caps usually pop, but not smoke.
What happens if a capacitor is abused?
If properly abused, that capacitor would make quite a bang and mess. It is unlikely that the bang would kill you even if you were a couple of feet away, but you can't rely on that, and it could certainly hurt you pretty severly. A serious injury like loosing one or both eyes isn't far fetched at all. The secondary effect could be quite serious too.
