Aluminum electrolytic capacitors, or aluminum electolytics, are polarized capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. The aluminum foil acts as the cathode, and electrolyte, typically established by a wetting agent, serves as the dielectric.

The MAL211948151E3 is an aluminum electrolytic capacitor that falls into this category. This capacitor series is characterized by its low impedance and good noise attenuation. It can be used in a wide range of applications, ranging from DC blocking to signal filtering.

Applications

The MAL211948151E3 is commonly used in power supplies and oscillators. In power supplies, it can be used as a smoothing capacitor, reducing input voltage ripple and output voltage fluctuations. In oscillators, it is often used as an output filter, optimizing the output waveforms and improving power efficiency. It is also well suited for integrating complex motor control systems.

The MAL211948151E3 can also be used in a variety of other applications. It is effective in pre-charge applications such as AC-DC power supplies and SMPS. It can also be used as a charge/discharge buffer in devices such as inverters and UPS systems.

Working Principle

The working principle of the MAL211948151E3 is based on the electrolyte being ionized by a voltage, causing the positive ions to form an electric double layer on the anode. The negative ions then move to the cathode, allowing the electric field to be formed between the two plates. This electric field results in the energy storage capability of the capacitor.

The MAL211948151E3 is designed to be extremely reliable, and has a working life of more than 3000 hours at an ambient temperature of -25 to +85°C. It can withstand high levels of vibration, atmospheric pressure, and ESD-static pulse.

Conclusion

The MAL211948151E3 capacitor series is an efficient solution for a wide range of applications, especially in the fields of power supplies, oscillators, and motor control systems. The electrolyte-based working principle allows for the energy storage capability of the capacitor, while the robust design ensures reliable performance and long working life.
