Aluminum Electrolytic Capacitors are small electronic components which are mostly used in electronic circuits. The SK471M016ST is one such type of aluminum electrolytic capacitors which is used in various applications. This capacitor is ideally suited for power supply and energy storage due to its high capacitance value. This article will discuss the application field and working principle of SK471M016ST.

SK471M016ST is a type of non-polarized aluminum electrolytic capacitor, and its application field mainly includes power and energy storage, such as voltage stabilization module, switching power supply, UPS uninterruptible power supply, etc. It features a higher capacitance-to-volume ratio and lower ESR, making it very efficient for power supply and energy storage.

The working principle of the SK471M016ST is quite simple. It consists of two metal electrodes, usually tin-plated aluminium foil, which are separated by a semi-permeable membrane. An electrolyte covers the electrodes and semi-permeable membrane. When a voltage is applied to the capacitors, electrons migrate from one electrode to the other, forming an electric double layer between the two electrodes. This electric double layer, or capacitance, stores the energy and when the voltage is removed, the capacitance is released, providing the stored energy.

The SK471M016ST has an operating temperature range of -55 to +105 °C, and its capacitance can range from 4,700 to 4700 µF. Its AC working voltage range is from 16V to 50V, with a rated ripple current of 4.19A. Other important parameters of this capacitor include its insulation resistance of over 10,000 MΩ, dielectric strength of 250 V/μs, and maximum self-healing of 0.5A. All of these parameters make SK471M016ST an ideal solution for applications requiring capacitance at higher temperatures and higher ripple currents.

In conclusion, the SK471M016ST is a type of non-polarized aluminum electrolytic capacitor which has a wide application field. It is specifically suited for power and energy storage applications such as voltage stabilization modules, switching power supplies, and UPS uninterruptible power supplies, due to its high capacitance-to-volume ratio and low ESR. The working principle of the capacitors is also quite simple, involving two metal electrodes which are separated by a semi-permeable membrane and covered with an electrolyte. This capacitor is also known for its high stability, durability, and long lifespan.
