UPM1J390MED

Aluminum electrolytic capacitors are electronic components that are widely used in every area of electronic products and systems. The UPM1J390MED is a great example of this type of capacitor. It is a surface-mount, radial-style aluminum electrolytic capacitor with a maximum rated voltage of 16V and a capacitance of 390uF. It is an ideal choice for applications requiring a high capacitance and wide voltage range, such as audio equipment, telecommunications equipment, and other industrial and consumer electronics.

Aluminum electrolytic capacitors are comprised of two aluminum plates electrode coatings, a spacer, and a dielectric material. This type of capacitor is characterized by its high capacitance to volumetric ratio. The UPM1J390MED is designed with a much larger surface than standard radial lead capacitors, which gives it a greater capacitance and higher voltage. The high capacitance makes it ideal for dc-dc converters and power supplies, as well as for energy storage and filtering.

In terms of working principle, the UPM1J390MED capacitor utilizes the Faraday Law of Electrolysis. When a voltage is applied between the two electrodes, the positive plate of the capacitor becomes positively charged while the negative plate becomes negatively charged. This creates an electric field between the two plates. This field creates a capacitance between the two plates, or more specifically, the greater the electric field, the greater is the capacitance. The electric field, in turn, is determined by the voltage applied, thus the greater the voltage applied, the greater is the capacitance.

This type of capacitor can also exhibit superb electrical characteristics, such as high stability, low ESR, as well as a high cycle life. This makes it well-suited for high-frequency applications, such as switching regulators, microprocessor-based systems, and other power systems. The UPM1J390MED can also handle a maximum rated temperature of 105°C, and is UL, CE, and RoHS approved, making it a safe and reliable choice for many electronic applications.

In conclusion, the UPM1J390MED is a great choice for applications requiring high capacitance, wide voltage range, and good stability. Its aluminum electrolytic design makes it ideal for filtering, energy storage, and dc-dc converters, and its high temperature and and voltage ratings make it suitable for use in many high-frequency and power systems. This versatile and reliable component is an excellent choice for all sorts of electronic applications.
