Sino-European Aluminum Electrolytic Capacitors

Are polymer hybrid aluminum electrolytic capacitors sustainable?

PHAECs have obvious environmental advantages over liquid AECs and polymer AECs. The study is beneficial to the sustainable development of future PHAEC products. Polymer hybrid aluminum electrolytic capacitors (PHAECs) are a new generation of aluminum electrolytic capacitors (AECs) following traditional liquid AECs (LAECs) and polymer AECs (PAECs).

What types of capacitors are available?

Our product portfolio at a glance: Aluminum electrolytic & aluminum polymer capacitors, film capacitors & energy capacitors (energy-c).

What is an aluminum electrolytic capacitor?

Except for a few surface-mount technology (SMT) aluminum electrolytic capacitor types with solid electrolyte systems, an aluminum electrolytic capacitor consists of a wound capacitor element, impregnated with liquid electrolyte, connected to terminals and sealed in a can.

What is a non polar aluminum electrolytic capacitor?

In non-polar aluminum electrolytic capacitors and motor-start aluminum electrolyte capacitors a second anode foil substitutes for the cathode foil to achieve a non-polar capacitor in a single case. These figures show typical constructions of the non-surface-mount aluminum electrolytic capacitors.

What are the tolerances for aluminum electrolytic capacitors?

While tolerances of ±5% and ±10% are routine for ceramic capacitors, ±20% and –10% +50% are the norms for aluminum electrolytic. This makes aluminum electrolytics the choice for high-capacitance applications like rectification filters and power hold up where more capacitance is a bonus.

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.
