4 FAQs about Canberra Super Aluminum Electrolytic Capacitor

What is a conductive polymer hybrid aluminum electrolytic capacitor?

Conductive Polymer Hybrid Aluminum Electrolytic Capacitors (Hereinafter called capacitor) that uses highly conductive polymer electrolytic materials and electrolyte. Please read the following in order to get the most out of your capacitor.

What is an aluminum electrolytic capacitor?

An aluminum electrolytic capacitor with a non-solid electrolyte always consists of two aluminum foils separated mechanically by a spacer, mostly paper, which is saturated with a liquid or gel-like electrolyte. One of the aluminum foils, the anode, is etched (roughened) to increase the surface and oxidized (formed).

Can aluminum electrolytic capacitors withstand overvoltage?

Aluminum electrolytic capacitors can generally withstand extreme overvoltage transients of limited energy. Application of overvoltage more than about 50 V beyond the capacitor's surge voltage rating causes high leakage current and a constant-voltage operating mode quite like the reverse conduction of a zener diode.

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.
