6 FAQs about [The function of aluminum cover mold for capacitor]
What happens if you cover a non-solid aluminum electrolytic capacitor with resin mold?
For a non-solid aluminum electrolytic capacitor, covering up the entire surface of the rubber seal with resin mold materi-als will obstruct the normal diffusion of internal hydrogen gas from the capacitor and result in serious failures.
Why do aluminum electrolytic capacitors have colossal capacitance?
Aluminum electrolytic capacitor construction delivers colossal capacitance because etching the foils can increase surface area more than 100 times and the aluminum-oxide dielectric is less than a micrometer thick. Thus the resulting capacitor has very large plate area and the plates are intensely close together.
What are aluminium electrolytic capacitors?
Aluminium electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminium foil with an etched surface. The aluminum forms a very thin insulating layer of aluminium oxide by anodization that acts as the dielectric of the capacitor.
What affects the lifetime of aluminum electrolytic capacitors?
The lifetime of aluminum electrolytic capacitors is affected mainly by the loss of electrolyte as the result of diffusion through the rubber seal materials, which leads to a decrease in capacitance and increase in tanδ.
Why do aluminum electrolytic capacitors have non-solid electrolytes?
Aluminum electrolytic capacitors with non-solid electrolytes have an exceptional position among electronic components because they work with an electrolyte as liquid ingredient. The liquid electrolyte determines the time-dependent behavior of electrolytic capacitors. They age over time as the electrolyte evaporates.
What influenced the development of aluminum electrolytic capacitors?
The development of tantalum electrolytic capacitors in the early 1950s with manganese dioxide as solid electrolyte, which has a 10 times better conductivity than all other types of non-solid electrolytes, also influenced the development of aluminum electrolytic capacitors.
