Aluminum Electrolytic Capacitors

The ALS81U392NF500 is an aluminum electrolytic capacitor. It is a type of passive electronic component used in a variety of electronic devices. An aluminum electrolytic capacitor consists of two aluminum foils separated by paper impregnated with an electrolyte. The paper is a insulator, and the two metal foils act as electrodes, with one side positive and the other negative. The capacitance value is determined by the size of the foils, the thickness of the paper, and the type of electrolyte used.

The ALS81U392NF500 is a radial-leaded, non-polarized aluminum electrolytic capacitor with a maximum operating voltage of 50 volts and a capacitance value of 0.39 microfarads. The application of this capacitor includes power supplies, audio amplifiers, and electrical circuits. It is also used in the filtering of power-supply ripple and as a bypass for smoothing DC signals in power amplifiers. This capacitor has a low ESR and is suitable for a wide range of frequencies, both AC and DC.

The working principle of an aluminum electrolytic capacitor is based on the ability of the electrolyte to store charge. The electrolyte is a mixture of water and various solutes such as sulfuric acid and potassium hydroxide. When the electrodes of the aluminum electrolytic capacitor are charged, an electric field is created in the paper which moves the ions in the electrolyte. The positive ions are attracted to the negative electrode and the negative ions to the positive electrode, resulting in a charge being stored. As electricity passes between the electrodes, the ions move, resulting in the buildup and discharge of electrical energy.

The ALS81U392NF500 has a long operating life and is capable of providing excellent performance even in harsh conditions. It is resistant to vibration and shock and also offers excellent stability against temperature. This aluminum electrolytic capacitor is also an environmentally friendly product since it does not contain hazardous substances, and it is RoHS compliant.

Overall, the ALS81U392NF500 is a versatile aluminum electrolytic capacitor that is perfect for use in a variety of applications. It has a wide operating range and is highly reliable. The aluminum electrolytic capacitor is also very affordable and easy to install, making it a great choice for designers looking for quality and affordability.
