Introduction

Aluminum electrolytic capacitors (AECs) are electronic components capable of storing electrical energy. The two types of AECs available are polarized and non-polarized. The polarised type has a positive and a negative lead, while the non-polarised type does not have leads at all. Typically, AECs are used for filter applications, smoothing purposes and even energy storage.

ALS71U752NS550 Aluminum Electrolytic Capacitor

The ALS71U752NS550 capacitor is a surface-mountable, anodized, polarised, mini-radial aluminum electrolytic capacitor. This capacitor has a capacitance value of 4700μF (micro farad) at a rated voltage of 25V. It has a leakage current of less than 2.1μA and an ESR rating of 65mΩ (milli ohms). The dimensions of the capacitor are 7.3 (Diameter) * 7.5 (Length) mm. The temperature range for which this capacitor can handle is from -40°C to 105°C.

Application Field and Working Principle

The ALS71U752NS550 capacitor is mainly used for environmental noise reduction by smoothing out short bursts of energy. This capacitor is widely used in modern electronic circuits and in power electronics. It can also be used for energy storage, power filtering and signal filtering.The working principle of AECs is that aluminum acts as an anode and cathode, while an electrical insulating oxide film acts as the dielectric. When voltage is applied to an AEC, it creates a layer of ions on the oxide film. This, in turn, creates an electric field and thus a capacitance. The capacitance of an AEC is almost independent of frequency, while its leakage current is frequency dependent. This makes them well suited to many applications, including filter applications.

Conclusion

The ALS71U752NS550 capacitor is a reliable and robust aluminium electrolytic capacitor that is widely used in modern electronics. It has a wide temperature range and also a good capacitance value. Its application mainly focuses on noise reduction, power storage and filtering. The working principle of the capacitor is based on the layer of ions created on the oxide film, which creates an electric field and thus a capacitance.
