Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components used mainly in power supplies and audio applications. These are very low capacitance, large size capacitors able to handle very high voltage. Aluminum electrolytic capacitors are the most versatile form of electrolytic capacitor type and are of two basic types: polar (also known as non-polar) and bipolar. They differ in their methodology of storing energy – polar capacitors use reverse leakage current and both AC and DC components, whereas bipolar (or non-polar) capacitors use only AC components.

The URS2G470MHD is a type of aluminum electrolytic capacitor manufactured by Nichicon, and is heavily used in power supplies, power management systems, consumer electronic electronics and automotive systems. It is one of the most popular types from Nichicon, offering excellent performance and reliability. It has a maximum capacitance of 2.2 µF, an operating voltage of 16V, a self-healing electrical failure system, and a product lifetime rating of up to 2000 hours.

The main application of the URS2G470MHD is in power supply applications. Due to its low capacitance, it can be used to filter power coming from a low voltage source, reduce electrical noise, and reduce output ripple. It can also be used as an additional buffer against voltage spikes in circuits driven by various means such as PWM, switching power supplies and others. Additionally, it can be used to provide transient protection in sensitive systems or as input filters to reduce the amount of electrical noise being picked up.

The working principle of the URS2G470MHD is similar to most aluminum electrolytic capacitors. It has a metal oxide layer between two aluminum foil electrodes and uses an anode and cathode fluid to cause reversible electrical charge flow. When a voltage is applied across the terminals, an electric field is formed, affecting the molecules in the anode fluid and causing them to be attracted towards the cathode. This generates holding force, and the capacitor stores energy in the field of attraction between these two charges.

When the charge becomes equal and opposite to the one that initiated it, the molecules of the anode fluid return to their original positions. This charge and discharge cycle can be repeated an indefinite number of times, provided that the capacitance does not exceed its maximum rating. The URS2G470MHD has a very low and stable leakage current, allowing for high-efficiency energy conversion. Additionally, its self-healing system enables the component to recover from any electrical short-circuits.

In conclusion, the URS2G470MHD is an ideal aluminum electrolytic capacitor for use in power supply applications. It has low capacitance, high voltage, low leakage current, and a self-healing system. It is also highly reliable, with a product lifetime of up to 2000 hours. This makes it one of the most popular aluminum electrolytic capacitors used in today\'s industrial and automotive applications.
