This type of capacitor is a polarized aluminum capacitor constructed in which aluminum is an anode and selenium (Se) cathode is treated with electrical oxide film on the dielectric material. The MAL214890155E3 capacitor has a capacitance of 470μF and is rated an operating voltage of 25V. It has a voltage range of 10 - 28 VDC and an operating temperature range of -40°C - 105°C.

Application Field of MAL214890155E3

The MAL214890155E3 is ideal for a wide range of power supply and DC-DC applications such as DC/DC Conversion, Inverters, Power Line Feeding, and Voltage Regulation. This capacitor has a voltage range of 10–28 VDC, enabling it to handle large surges of power from engines or power supplies. It is also very resistant to temperature fluctuations, making it perfect for use in environments where temperature could rapidly change. This makes the MAL214890155E3 well-suited for use in industrial, automotive, and energy storage applications.

Working Principle of MAL214890155E3

The MAL214890155E3 utilizes an aluminum anode and a Selenium (Se) cathode. The anode is connected to the ground and the cathode is connected to a peak/average voltage oscilla-tion unit to form the circuit. When the voltage across the capacitor is applied, an electric field is created between the anode and the cathode. This electric field creates a charge, causing electrons to be moved from the anode to the cathode. As the electrons flow, an electrical current is created in the circuit. The result is a stored electrical energy, which is what capacitance measures.

The MAL214890155E3 can handle high voltage spikes because of its large capacitance. This capacitance is achieved through the thickness of the oxide layer between the aluminum anode and the selenium cathode. The thicker the oxide layer, the higher the capacitance. The working principle of this capacitor prevents the voltage across it from becoming too large and damaging the circuit.

Conclusion

The MAL214890155E3 aluminum electrolytic capacitor from Murata is a highly reliable device designed for power supply and DC-DC applications. The capacitor offers a large capacitance and is able to withstand large voltage spikes. It is also highly resistant to temperature fluctuations, making it suitable for use in industrial and automotive applications. Due to its broad range of features and applications, the MAL214890155E3 is a great choice for those looking for a reliable and versatile capacitor.
