Aluminum Electrolytic Capacitors

The 380LQ561M250H042 aluminum electrolytic capacitor is a cylindrical, non-solid electrolytic capacitor consisting of an anode, which is made of aluminum, and a cathode, which is made of electrolyte. As a type of polarized capacitor, it has two leads, with the negative lead usually marked with a stripe.

The 380LQ561M250H042 aluminum electrolytic capacitor offers a range of advantages, including its larger capacitance, higher voltage ratings, lower equivalent series resistance (ESR), and longer operational lifespan compared to other types of capacitors. The main benefit of using aluminum electrolytic capacitors is that they are able to store more energy and have a larger dielectric breakdown field than other types of capacitors, allowing for higher voltage ratings.

The main application field of the 380LQ561M250H042 aluminum electrolytic capacitor includes power supplies, suppressed noise circuits, and audio crossover networks. The capacitor is also often used to provide short circuit protection to other components in the circuit or to provide statistical voltage regulation. It can be used in single-phase or multi-phase power supplies to filter out radiofrequency interference (RFI) or low-frequency noise.

Working Principle

Unlike non-polarized capacitors, aluminum electrolytic capacitors have two terminals – a positive (anode) and a negative (cathode) terminal. An electric charge builds up in the capacitor when a voltage is applied to its two terminals. The electric charge is initially stored on the anode as an oxide layer – this is what allows the capacitor to store a large amount of charge. The electric charge is then released when the voltage is reversed, allowing electric current to flow from the cathode to the anode.

When the applied voltage across the capacitor becomes too large, the electric field between its two terminals (which is proportional to the voltage) becomes greater than the breakdown field of the oxide layer. This can cause a short circuit between the anode and the cathode, leading to rapid discharge of the electric charge stored in the capacitor. This is why aluminum electrolytic capacitors have higher voltage ratings compared to other types of capacitors.

The size of the oxide layer can also affect the amount of charge stored in the capacitor. The oxide layer slowly decreases in size over time due to the migration of ions between the anode and the electrolyte. This is why aluminum electrolytic capacitors have a limited lifespan and must be replaced periodically.
