Aluminum Electrolytic Capacitors

The 100YXG470MEFCGC18X31.5 capacitor is an aluminum electrolytic capacitor that uses a leakage resistant organic solid electrolyte to increase its long-term reliability. It features a high capacitance and low equivalent series resistance (ESR). This type of capacitor also has an unlocked memory as part of its design.

Application Field

The 100YXG470MEFCGC18X31.5 aluminum electrolytic capacitor is typically used in electronic equipment, such as computers, notebooks and other personal electronic devices, to smooth electrical signals and provide filtering for power supplies. It is also used in DC/DC converters, LCD inverters, motor drives and other applications that require a high capacitance or a low ESR.

Working Principle

The aluminum electrolytic capacitor is based on the principle of a conventional capacitor, where an electrolyte, typically aqueous electrolyte, is used to store electrical charge in an enclosed space. However, in an aluminum electrolytic capacitor, an organic solid electrolyte is used instead of an aqueous solution. This allows for a higher capacitance and a wider range of operational temperature.

The aluminum electrolytic capacitor relies upon a thin oxide film formed from a reaction between anodized aluminum and the organic electrolyte. The thin film provides high capacitance and a low ESR. The electrolyte also provides a barrier against leakage and free radical formation. When in operation, current enters a capacitor plate, resulting in a decrease of potential on the plate. This causes a corresponding increase in the potential on the other plate. The two plates are disconnected during this process and the field created maintains the charge until the current stops.

The 100YXG470MEFCGC18X31.5 aluminum electrolytic capacitor has a rated capacitance of 470uF and an ESR of 18mOhm. It has a temperature range of -40°C to +105°C. It is also rated for 2000 hours at 105°C and has a maximum ripple current rating of 1.45A at 100KHz.

The 100YXG470MEFCGC18X31.5 aluminum electrolytic capacitor is widely used in various applications due to its high capacitance, low ESR, wide temperature range, long life and low leakage. It is one of the most reliable and efficient types of capacitors available today.
