Aluminum Electrolytic Capacitors: SMG350VB47RM20SLL Application Field and Working Principle

Aluminium electrolytic capacitors (electrolytic capacitors, aluminum electrolytic capacitors, or electrolytic aluminum capacitors) are capacitors which make use of electrolyte as one of its two electrodes. This type of capacitor is capable of storing a moderately high amount of electrical energy since their capacitance values range from 1µF to several thousand µF.The SMG350VB47RM20SLL is a radial-style aluminium electrolytic capacitor ideal for applications in a wide variety of settings, such as battery-operated devices, power supplies, electronic circuit boards, and electronic control systems. The device is a type of non-polarized electrolytic capacitor, containing a water-based electrolyte solution which provides a high capacitance-to-volume ratio and a high level of reliability.

Working Principle

Aluminium electrolytic capacitors rely on a thin oxide layer formed on its aluminium capacitor anode, through the electrolyte solution, to provide insulation between the capacitor\'s electrons and its conductive electrolyte. This thin oxide layer is what allows the capacitor to maintain a high capacitance-to-volume ratio, and is key in providing the device\'s stability and reliability.This oxide layer acts as an insulating dielectric material when a voltage is applied across the anode and the cathode. In the case of the SMG350VB47RM20SLL, its anode is made from a high-quality aluminium which provides excellent tolerances and a low level of thermal expansion, thus allowing the capacitor to better handle a variety of DC or AC voltage in different applications.The electrolyte solution used in aluminium electrolytic capacitors can be either aqueous or non-aqueous. The aqueous solutions are considered to be more reliable and will generally have a higher capacitance-to-volume ratio than their non-aqueous counterparts. SMG350VB47RM20SLL uses an aqueous electrolyte solution, paired with its high quality anode material, allowing for reliable performance in a variety of different configurations.

Application Field

The SMG350VB47RM20SLL is a versatile non-polarised electrolytic capacitor, and thus suitable for a large variety of applications across many industries. It can be used in a wide range of battery-operated equipment, such as mobile phones and tablets, as well as in power supplies, power management systems, and solar panels.Furthermore, these capacitors can be used in electronic control systems thanks to their ability to handle a wide range of DC or AC voltage while still providing reliable performance. Additionally, the SMG350VB47RM20SLL can be used in automotive, communications, medical, and industrial applications.Finally, the SMG350VB47RM20SLL can be used as an output filtering or decoupling capacitor in electronic circuit boards as well. Its high-quality anode allows for wide margins of operation, and its reliable aqueous electrolyte solution provides stability across different frequencies.

Conclusion

The SMG350VB47RM20SLL is a high-quality radial electrolytic capacitor ideal for a variety of applications. Its stable construction alongside its excellent capacitance-to-volume ratio makes it suitable for a wide range of devices, from small consumer electronics to large industrial systems. Its non-polarised electrolyte, paired with its reliable aqueous solution, allows it to provide a high degree of stability and reliability in a wide range of temperature and voltage ranges.
