Abuja Super Aluminum Electrolytic Capacitor

What are aluminium electrolytic capacitors?

Aluminium electrolytic capacitors (AECs) are known for their high specific capacitance, wide range of operating voltages and low cost compared to other capacitors , and have been widely used in daily consumer electronics, while demonstrating great potential in high energy and high-power applications , , , .

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.

What is the international standard for aluminum electrolytic capacitors?

The international standard for aluminum electrolytic capacitors is IEC 60384-4. The sectional specification mentioned above is complemented by a set of detail specifications that applies to specific design types (e.g. electrolytic capacitors with axial wire leads).

Are aluminum electrolytic capacitors reliable?

Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capacitors for high-reliability applications and capacitors for general-purpose applications. This differentiation has also been adopted in the relevant IEC standards.
