Aluminum Electrolytic Capacitors: UUJ2A331MRQ1MS Application Field and Working Principle

Aluminum electrolytic capacitors, or just electrolytic capacitors, are widely used in electronic systems. One of the most popular models is the UUJ2A331MRQ1MS capacitors by Nippon Chemi-Con. Let’s take a closer look at the application field and working principle of these types of capacitors.

Application Field of UUJ2A331MRQ1MS

The UUJ2A331MRQ1MS is an electrolytic capacitor with a 10V rating. It has a small surface, low ESR, and its capacitance range is 330 to 2200 μF. Its structure offers exceptional long life, making it an ideal capacitor for a variety of industrial and consumer electronic applications such as power and audio systems.The UUJ2A331MRQ1MS has a lead configuration of 1-pole, 90° through-hole. It has a bandwidth of up to 100 kHz and an operating temperature range of -55°C to +105°C. It is also designed to offer high current characteristics for resistance to low DC bias current.

Working Principle of UUJ2A331MRQ1MS

The UUJ2A331MRQ1MS is an electrolytic capacitor, which means that it relies on electrolytes set between aluminum foil plates. An electrolytic capacitor works in the same way as a conventional electrical capacitor, except it has an electrolyte instead of a dielectric.Whenever a capacitor is connected to a DC power source, the current flows from the positive terminal to the negative terminal. During the charging process, electrons are added to the plates of the capacitor, creating a negative charge on one plate and a positive charge on the other. This the voltage difference across the plates stores energy.When the capacitor is connected to a circuit, the charges on the plates interact with each other and create a current with a specific frequency. This frequency is determined by the capacitance of the capacitor and the load on the circuit.When the voltage across the plates of the capacitor is equal to the input voltage, the current reversal and the capacitor is now “filled” with energy. At this point, the capacitor is acting as a resistor and providing a constant voltage to the circuit.

Conclusion

The UUJ2A331MRQ1MS aluminum electrolytic capacitor is a reliable and versatile component for a variety of applications. It is compact and has low ESR and a wide capacitance range, making it suitable for many high-performance industrial and consumer applications.This capacitor also has a long life and is designed to offer reliable performance in a wide range of temperatures, from -55°C to +105°C. The electrolyte-filled plates provide a low DC bias current to resist current spikes and offer a constant voltage for long periods.
