This is, I believe, how one arrives at the situation of having a ''non-polarized electrolytic'' capacitor. follow up - turns out that what might LOOK like two ordinary electrolytics are not, in fact, two ordinary electrolytics. Despite the uncanny resemblance to exactly that, it is highly probable that the devices I saw had other properties as well.

6 FAQs about [What is the error of electrolytic capacitors ]
How does an electrolytic capacitor fail?
The vast majority of electrolytic capacitor failures are caused by one or more of the following mechanisms: dry-out of the electrolyte, loss of adhesion between the electrode and electrolyte, corrosion of the electrode, or breakdown of the dielectric.
What causes electrolytic capacitor degradation?
It is important that designers understand what causes electrolytic capacitor degradation. When an electrolytic capacitor fails, it can be because of a short circuit, circuit damage, or even an explosion. Most electrolytic capacitor degradation results from a common failure mode: the vaporization or leakage of electrolyte.
What type of capacitor is most likely to fail?
Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.
What are the causes of short circuits in electrolytic capacitors?
The failure of the electrolytic capacitor in a circuit can cause a short circuit (due to mechanical failure), open circuit (manufacturing defect, mechanical failure), loss in capacitance, and high ESR. Short Circuit: Short circuits between the electrodes can occur due to vibration, shock, or stress on leads.
What happens if aluminum electrolytic capacitors fail?
Failing aluminum electrolytic capacitors can have significantly adverse effects on electronic circuits. Most technicians have seen the tale-tell signs – bulging, chemical leaks, and even tops that have blown off. When they fail, the circuits that contain them no longer perform as designed – most often affecting power supplies.
