Aluminum electrolytic capacitors are passive electronic components that play a major role in electrical circuits due to their charge-storage capabilities. Among various dedicated capacitors, the 139R263M7R5AA2A aluminum electrolytic capacitor is one of the most popular ones. It serves a critical role in maintaining an optimized electrical environment for various systems.

Introduction

139R263M7R5AA2A aluminum electrolytic capacitor is a type of capacitor that uses aluminum oxide film as the dielectric material. As the dielectric, the aluminum oxide helps form a pseudocapacitance at the interface between the anode and the electrolyte. Its configuration allows for a higher charge density than other—similarly sized—capacitors. As the charge density increases, it creates a very low impedance, making it suitable for high frequency, interference suppression, and power filtering applications.

Application Fields

The 139R263M7R5AA2A aluminum electrolytic capacitor has a wide variety of applications and is extensively used in aerospace, automotive, consumer electronics, industrial, medical, and telecom fields. Its low impedance, high capacitance size, and long service life all make it fit perfectly for various types of electronic systems. For instance, the capacitor can be used to filter high-voltage DC power supplies in heavy-duty applications such as industrial and telecom. Meanwhile, the capacitor is applicable in a range of motors such as electric window motors in cars. On the other side, the device is also a key component in stabilizing signals and preventing circuit malfunctions in consumer electronics.

Working Principle of the 139R263M7R5AA2A

The 139R263M7R5AA2A aluminum electrolytic capacitor is a polarized capacitor. Its design features an anode that is solid aluminum conductor with extremely thin aluminum oxide film. On the opposite side, the cathode is a solid aluminum oxide called a cathode foil. As positive voltage is applied, the electrons are attracted to the positiveside of the capacitor, forming an electric field. Since the dielectric is the aluminum oxide, it acts as a barrier that creates an “electrical clamp” between the anode and the cathode. When the voltage drops, the electrons released back to the anode, completing an electrical cycle.

Key Specifications and Parameters of the Device

The 139R263M7R5AA2A aluminum electrolytic capacitor is a non-inductive, polarized capacitor. Its capacitance value ranges from 0.1µF to 10µF, and it can be used at temperatures ranging from -40°C to +105°C. The device has a maximum voltage rating of 450V DC and a rated voltage ranging from 170V to 250V DC. It is also able to withstand high frequency ripple at a maximum of 20kHz.

Conclusion

The 139R263M7R5AA2A aluminum electrolytic capacitor is an indispensable addition to any electrical and electronic systems. It features excellent features, such as a high capacitance, high frequency ripple, and wide operating temperature range. What’s more, its low impedance ensures super-fine electricity transmission, making it one of the top choices in the capacitor industry. This multi-purpose capacitor has been adopted by many industries and fields, and it is the perfect choice for applications such as interference suppression and power filtering.
