Aluminum electrolytic capacitors are widely used in electronic devices, and the PSU18935A is one of the most popular models of aluminum electrolytic capacitors available on the market today. Aluminum electrolytic capacitors are characterized by their ability to store electrical energy, and the PSU18935A is no exception. This model offers many benefits over other aluminum electrolytic capacitors, making it a top choice for electronic applications.The PSU18935A is a polarized aluminum electrolytic capacitor with a cylindrical can form in which the electrolyte is contained. The operating temperature range of this model is -40 to +85°C and its electrolyte can tolerate temperatures up to +125°C. It has a 10% tolerance with a nominal value of 150uF and a working voltage of 50V.When it comes to the application field of the PSU18935A, this model is ideal for use in power supplies for audio systems, amplifiers, microscopes, and other electronic devices requiring a level of electrical stability. The PSU18935A is also commonly used to reduce circuit noise, improve control over low-frequency signals, and filter out interference. Additionally, it is well-suited for large current applications due to its high temperature range and high ripple current capabilities.The PSU18935A also excels in terms of its working principle. It is polarized, meaning that it has an anode and a cathode and the application of a voltage must follow the correct polarity. This is the key difference between polarized and non-polarized capacitors. The anode and cathode are both made of aluminum and the electrolyte, which is usually an aqueous solution of sulfuric acid, acts as a dielectric between them.When a voltage is applied, the negative charges move through the electrolyte and deposit on the anode as aluminum oxide. This forms a layer of aluminum oxide which acts as a dielectric. The positive charges then move through the electrolyte and deposit on the cathode, forming a layer of aluminum hydroxide. This forms an insulating layer which is the dielectric layer.As a result, the negative charges stored in the aluminum oxide layer repel each other, creating an electric field that opposes the application of a voltage. This is what gives aluminum electrolytic capacitors their high capacitance value and makes them perfect for large current applications.The PSU18935A is an excellent choice for applications requiring stable voltage levels over long periods of time. Its application field and working principle make it an ideal component for many types of electronic devices. It is strong, reliable, and energy-efficient, making it a top choice for those looking for a component that will provide the highest level of performance.
