Aluminum electrolytic capacitors are one of the most widely used electrical components. The model SMG35VB392M20BLL is no exception, with many applications in electronics and engineering. This article will explain the field of application for the SMG35VB392M20BLL and the working principle behind it.

The SMG35VB392M20BLL capacitor is a non-solid aluminum electrolytic. It is most commonly used as a decoupling or filter capacitor in analog and digital signal circuits. This capacitor is suitable for circuits that operate in temperatures from -40°C to +110°C. The stated capacitance range is from 39µF to 120µF. Capacitance will decrease by 20% at a temperature of +25°C and drop by almost 40 to 50% at +85°C.

The SMG35VB392M20BLL\'s working principle is based on the Helmholtz double-layer concept. An aluminum oxide layer on the surface of the aluminum substrate provides a separation between the two layers of ions, preventing direct contact between the two metals. The aluminum oxide layer thus serves to create a space charge that is directly proportional to the impedance between the two electrodes, resulting in high capacitance. By increasing the surface area of the aluminum, more ions are able to be stored and the capacitance increases.

In addition to non-solid aluminum capacitors, the SMG35VB392M20BLL is also frequently used in combination with electrolytic capacitors. The combination of the two components is sometimes used as a low-noise filter. Due to the double-layer concept, the SMG35VB392M20BLL is capable of delivering very low levels of noise compared to other aluminum electrolytic capacitor types.

The SMG35VB392M20BLL is also suitable for a variety of applications related to voltage regulation, such as DC/DC converters and battery management systems. It is well suited for use in power supply circuits, where a combination of electrolytic and aluminum electrolytic capacitors are used to reduce output ripple and improve uniformity. The SMG35VB392M20BLL is also popular in audio applications, where it can provide excellent AC impedance characteristics at low frequencies.

In summary, the SMG35VB392M20BLL is a versatile aluminum electrolytic capacitor designed for a variety of applications. Its double-layer structure provides excellent capacitance and low noise performance, making it ideal for use in analog and digital signal circuits, audio applications, and voltage regulation circuits.
