Aluminum electrolytic capacitors are, in general terms, the most widely used power capacitors in the world today. They are mainly used in dc-dc converters, power supplies and other related applications. The UPW1E472MHD Aluminum Electrolytic Capacitor is a unique device designed for applications with very high power densities. It uses an aluminum oxide layer as its dielectric, which is deposited on an aluminum foil. The ultra-thin dielectric layer is then subjected to electrical fields which effectively increase the capacitance of the device and give it superior electrical performance.The UPW1E472MHD Aluminum Electrolytic Capacitor is typically used in the application of high voltage DC power supplies, computers, and communications systems. Its main purpose is to filter AC pollution from directly connected power lines. As DC is a more stable voltage source, it needs fewer filtering components compared to AC power. This is where the UPW1E472MHD Aluminum Electrolytic Capacitor comes into play. By providing a large capacitance, it is able to filter out a significant amount of noise and reduce the ripple and EMI (electromagnetic interference) in the system.The capacitance of the UPW1E472MHD Aluminum Electrolytic Capacitor mainly depends on three factors: the size of the aluminum foil, the thickness of the dielectric layer, and the dielectric breakdown voltage of the aluminum oxide. The physical size of the aluminum foil is important for the capacitance as a smaller foil area will lower the capacitance. The thickness of the dielectric layer is also an important factor; a thinner layer will result in a higher capacitance. Lastly, the dielectric breakdown voltage of the aluminum oxide layer plays an important role in determining the capacitance. The higher the breakdown voltage of the aluminum oxide layer, the higher the capacitance will be.The UPW1E472MHD Aluminum Electrolytic Capacitor has a very wide operating temperature range, from -55°C to 125°C. The high temperature range allows the capacitor to be used in applications where high operating temperatures are commonly found. It also has a low dissipation factor which ensures low energy losses and increases its performance in applications such as dc-dc converters and power supplies.The UPW1E472MHD Aluminum Electrolytic Capacitor is a reliable device with high voltage ratings and long life span. It is a very effective device when used in high voltage applications, due to its increased capacitance and high temperature resistance. In conclusion, the UPW1E472MHD Aluminum Electrolytic Capacitor is an excellent power capacitor for applications that require high power densities and long product life.
