6 FAQs about [Low voltage capacitors non-liquid impregnation]
What is a non-solid electrolytic capacitor?
The electrolyte in non-solid electrolytic capacitors is a biodegrad-able liquid based on a stable solvent with a high boiling point as the main ingredient. The most common solvent is ethylene glycol (EG). Gammabutyrolactone (GBL) or other solvents may also be used.
What types of aluminum electrolytic capacitors are not covered?
Other types of aluminum electrolytic capacitors not cov-ered include the obsolete wet types without separator mem-branes, “hybrid” aluminum electrolytic capacitors containing both polymer and liquid electrolyte components and sol-id-polymer electrolytic capacitors.
What are polar non-solid aluminum electrolytic capacitors?
This guide covers the application of polar, non-solid aluminum electrolytic capacitors, which are those aluminum electrolytic capacitors featuring a wet, aqueous electrolyte with separator membranes such as cellulosic papers between two aluminum foils.
What is an aluminum electrolytic capacitor?
An aluminum electrolytic capacitor consists of a wound capac-itor element, impregnated with liquid electrolyte, connected to terminals and sealed in a can. See Figures 1 and 2. Voltage ratings are classified as < 100 VDC for low voltage, 101-250 for mid-voltage and 251-700 for high voltage.
Which capacitor should I use for charge-discharge applications?
For charge-discharge applications use capacitors designed for that use, such as our and strobe capacitors, Type PF, 7P photoflash and ST, or contact us for a special design for your requirements. High continuous ripple voltage can eventually have the same efect as charge-discharge duty, only to a lesser degree.
Can aluminum electrolytic capacitors withstand rapid charging?
Aluminum electrolytic capacitors can generally withstand rapid charging along with occasional overvoltage transient spikes of limited energy. If transients above the capacitor’s rated DC volt-age are anticipated in the application, please contact us to dis-cuss the best capacitor for the application.
