Aluminum electrolytic capacitors are a type of electric component used to store electrical energy. USW1H4R7MDD aluminum electrolytic capacitors are manufactured and designed to be used under specific conditions and application fields. This article will discuss the application field and working principle of the USW1H4R7MDD capacitor.

Application Field of USW1H4R7MDD Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors with the USW1H4R7MDD series name are designed with a rugged case and cover to provide long-term reliable performance in extreme outdoor environments. They are also equipped with a long life design and an excellent ripple current capability. These features make them suitable for use in the automotive, agriculture, and marine industries. These capacitors can also be used in LED lighting applications, power systems, and industrial motor drives. They are available in can sizes ranging from 10 to 18mm and are rated up to 450 Vdc. These capacitors are suitable for both surface-mount and through-hole installations.

Working Principle of USW1H4R7MDD Aluminum Electrolytic Capacitors

The USW1H4R7MDD aluminum electrolytic capacitors operate using a simple electrolytic principle. This is done by sandwiching an electrolyte-soaked paper or wound foil between two aluminum plates, producing a capacitor with a high capacitance value. As electricity passes through the electrolyte, an electrical field is set up between the two aluminum layers, creating an electrical energy storage device capable of providing burst currents for a long period of time. The capacitance rating of these capacitors can be adjusted by varying the thickness of the aluminum plates or by using a thicker electrolytic paper or foil.

The USW1H4R7MDD aluminum electrolytic capacitors are designed to be two-terminal devices having two exposed plates. These plates are rated at different voltages, usually in the range of 25V to 250V. The voltage rating of each plate determines the current rating of the device. The electrolyte used in these capacitors varies with the application, but common electrolytes used in these capacitors include ammonium bicarbonate, ammonium sulfate, and sodium dodecylbenzenesulfonate.

Unlike other capacitors, aluminum electrolytic capacitors are not suitable for high frequency applications due to their low energy density and poor frequency response characteristics. They should not be used in high-frequency pulses or pulses that exceed the rated current. Additionally, the capacitance of aluminum electrolytic capacitors decreases with increasing temperature, making them unsuitable for high temperature applications.

The USW1H4R7MDD aluminum electrolytic capacitors are capable of providing ripple current capability for a long time and are rated for a life span of 5,000 hours and beyond. They have a maximum operating temperature range of -55˚C to +105˚C and can be used in an ambient temperature of +85˚C. The capacitors are designed to withstand reverse polarity and surge current capabilities, making them an excellent choice for automotive and power supply applications.

Conclusion

The USW1H4R7MDD aluminum electrolytic capacitors are manufactured and designed for use in specific application fields, particularly automotive and power supply applications. The capacitors are designed to provide long-term reliable performance in extreme outdoor environments and have an excellent ripple current capability. The aluminum electrolytic capacitor works using a simple electrolytic principle, where an electrolyte-soaked paper or wound foil is sandwiched between two aluminum plates. The capacitance rating of the aluminum electrolytic capacitor can be adjusted by varying the thickness of the aluminum plates or by using a thicker electrolytic paper or foil. These capacitors are rated for a long-term life span and capable of withstanding reverse polarity and surge current capabilities.
