Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electronic and electrical circuits, particularly in the filtering, decoupling, and buffering of high-frequency power electronics and RF systems. They offer excellent temperature stability, long service life and low-temperature derating.

200HXC680MEFCSN25X35 is a kind of aluminum electrolytic capacitor. The ‘H’ in the product code represents the product is a screw terminal type capacitor. The ‘X’ indicates the ceramic type base of the capacitor. ‘C’ means the capacitor has a high temperature (200 °C) rating and ‘SN’ means it is a sealed capacitor.

Application Field:

200HXC680MEFCSN25X35 is mainly used in power electronics systems, such as motor drivers, traction converters, UPS systems, and power supplies.

It is also ideal for use in other applications such as welding equipment, high-intensity discharge lamps, and high-efficiency power systems.

Working Principle:

Aluminum electrolytic capacitors have an anode made of a porous, sintered aluminum. The cathode is made of liquid electrolytic and a metal case. A charge exchange occurs when the applied voltage causes the ionization of the liquid electrolyte. This exchange creates a positive charge at the anode and a negative charge at the cathode.

The anode is able to store the charge because of its large surface area and porosity. This results in large capacitance values, but also makes them temperature-sensitive. The electrolyte, in addition to providing a charge exchange, acts as an insulator to prevent the current from flowing between the electrodes.

The electrical characteristics of these capacitors are strongly influenced by the purity and composition of the electrolyte, as well as the physical characteristics of the anode material. They are also affected by temperature, particularly high temperatures. That is why they are rated for high-temperature operation.

In addition to the above, 200HXC680MEFCSN25X35 aluminum electrolytic capacitors are designed to meet UL 94V-0 standards for flammability testing, in order to ensure safety and reliability.
