LDQ2D391MERYGA

Aluminum electrolytic capacitors are polarized capacitors designed to provide high capacitance compared to other types of capacitors. They are often used in applications where space requirements are critical, such as in portable electronics and components of modern digital systems. The LDQ2D391MERYGA is one such aluminum electrolytic capacitor.

Application Field

The LDQ2D391MERYGA is an expanded temperature, extended life, radial lead aluminum electrolytic capacitor. It is used in a variety of applications, such as adjustable power supplies and power supplies for temperature control and timer systems. Furthermore, this capacitor is also suitable for high frequency input filtering, as it is small in size and has wide capacitance range. Other application areas include telecommunications, switch-mode power supplies, DC/DC converters, and automotive electronics.

Working Principle

Aluminum electrolytic capacitors are constructed with a positive anode and a negative cathode, separated by an insulating electrolyte material. This creates two distinct sections, between which the electric charge is separated. The electrolytic material allows current to run in one direction only. This makes it an ideal choice for filtering out AC signals and power supplies.

The LDQ2D391MERYGA capacitor has an expanded temperature range of -50 to +125°C, making it suitable for more extreme temperature applications. This capacitor has a long life expectancy, as its micro-endur technology increases the working lifetime through double electrolyte injection and higher-than-normal bright tin plating. This technology also significantly reduces the occurrence of short-circuits, ensuring top-notch safety in harsh environments.
