Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electronic eqipment. They are constructed with welded aluminum cases, aluminum anode foil, and metalized cathode foil. The electrolyte is a solution of acids in water or organic solvents. The metalized cathode is coated with an insulating coating to reduce polarization and increase capacitance.

35YXG4700MEFC18X35.5 Application Field and Working Principle

The 35YXG4700MEFC18X35.5 aluminum electrolytic capacitor is part of a series of high voltage, high reliability, and long life aluminum electrolytic capacitors. It has a rated voltage of 350 VDC, a maximum ripple current of 2.86A/uf at 120 Hz, and a servicing life of 2000hrs at +105°C. This type of capacitor is suitable for use in high voltage power supply and high frequency switching power converters, and particularly in applications with wide temperature range and low temperature performance.

The working principle of the 35YXG4700MEFC18X35.5 aluminum electrolytic capacitor is based on the use of an electrolyte to create an electrical and chemical bond between the anode and cathode of the capacitor. The electrolyte creates an electrically conductive pathway between the anode and the cathode, which ensures a continuous electrical link. The electrolyte also absorbs electrical charge, which allows for a highly stable electrical connection even at high frequencies. Additionally, the electrolyte shields the capacitor from electrical noise and other interference.

Capacitance Characteristics

The 35YXG4700MEFC18X35.5 aluminum electrolytic capacitor has a very high capacitance-to-volume ratio, which can be used as a key performance parameter for assessing its performance. The capacitance-to-volume ratio of this type of capacitor is usually in the range of 10 to 20 pF/µm and depends on the specific type of aluminum electrolyte used in the production process. This relatively high capacitance-to-volume ratio is an advantageous characteristic as it allows the capacitor to store a larger amount of energy for the same volume. This is especially advantageous in applications such as high-voltage converters, as higher amounts of energy can be stored for a given amount of volume.

Reliability and Durability

The 35YXG4700MEFC18X35.5 aluminum electrolytic capacitor is noted for its high levels of reliability and durability. The capacitor is designed to withstand temperatures up to +105°C, as well as an operating life of up to 2000hrs. Additionally, the aluminum electrolyte used in the capacitor\'s production helps to ensure a low rate of polarization even at high frequencies. This helps to reduce or even eliminate any additional noise that could be generated by the capacitor, making it a reliable component over a wide range of operating conditions.
