UVR2A470MPD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are some of the most commonly used capacitors in electronic circuits and appliances, where they are employed for specific functions such as timing, filtering, bypassing, decoupling, or tuning. They have several advantages over other capacitor types, such as higher capacitance and lower equivalent series resistance, and are used in digital as well as analog circuits.

UVR2A470MPD-specific Applications and Working Principle

The UVR2A470MPD series aluminum electrolytic capacitor is a high-performance capacitor designed for a wide range of applications, from digital circuits to strong VRMs. The device is constructed with two main components: a housing and an aluminum electrolytic core. The housing is made of highly resistant materials and provides a pressure-tight seal, making it reliable and durable even in extreme environmental conditions. The aluminum electrolytic core is composed of two parts: a burnished anode band and a cathode band. When exposed to electrical current, the anode releases positively charged ions which come into contact with the negatively charged cathode, forming a polarized capacitor.

UVR2A470MPD capacitors are specially suited for applications involving high frequency and high temperature operations, as they are highly efficient in dissipating heat and have a wide temperature range (−40 to +105°C). The series\' high capacitance is ideal for VRM decoupling, which calls for low current flow and a high capacitance. Power supplies are also a suitable fit for this large-capacitance capacitor thanks to the long-life design of P-E construction that ensures low ESR, and increased temperature stability.

In addition to VRMs and power supplies, UVR2A470MPD capacitors are often used for automotive circuitry, wherever the need for a large capacitance, reliability and low ESR are important considerations. This includes applications like engine control, sensors and fuel injection systems. Withstanding ratings of up to 350V and an operational life of up to 8,000 hours, it is an excellent device for all types of automotive applications.

As with all aluminum electrolytic capacitors, the UVR2A470MPD capacitors have a polarity and must be installed correctly to avoid damage. An incorrect installation can cause the capacitor to fail prematurely, likely due to the buildup of high internal heat due to the wrong placement of the anode and cathode. It is therefore important to ensure the correct orientation of the component, particularly when connecting to other devices.

Conclusion

The UVR2A470MPD series aluminum electrolytic capacitors offer a number of advantages over other types of capacitors, making them ideal for a wide variety of applications including VRMs, power supplies and automotive circuitry. While it is important to ensure the anodes and cathodes are correctly oriented to avoid failure, their high capacitance, reliability, and thermal stability make them a great choice when a large capacitance is required.
