In this article, we will explore the application field and working principle of the UPJ1A392MHD.

Capacitance and Voltage Rating

The UPJ1A392MHD is a two terminal aluminum electrolytic capacitor with a capacitance of 3900 microfarads (µF). It also has a wide operating temperature range (-55°C to 105°C) and a voltage rating of 25 VDC. This capacitor is designed primarily for applications with higher ripple current requirements, such as power supplies and battery chargers. The capacitance and voltage rating of the UPJ1A392MHD make it a suitable choice for a wide range of operating conditions.

Size and construction

The UPJ1A392MHD aluminum electrolytic capacitor is housed in a compact, Pb-Free SMD (surface mount device) package. This package measures 7.3 mm in length and 5.7 mm in width, and is 0.6mm in height. Inside the package is a sealed aluminum electrolyte containing a snake-like series of aluminum and dielectric layers. These layers are separated by an electrolyte, which is a jellied conductive material containing aluminum ions, water and other chemicals. This combination of materials forms the capacitor, which is capable of storing an electrical charge.

Working Principle

The working principle of the UPJ1A392MHD aluminum electrolytic capacitor is based on the movement of electrons. Electrons flow through the aluminum layers of the capacitor, which act as a barrier to prevent the flow of electric current. As the capacitor charges, the electrolyte between the aluminum layers stores energy, which creates an electric field around the capacitor. This electric field interacts with the field created by the external power source and causes a voltage difference between the terminals of the capacitor. This voltage difference is responsible for the capacitor’s ability to store an electrical charge.

Application Field

The UPJ1A392MHD aluminum electrolytic capacitor is suitable for a wide range of applications. Due to its low impedance and good ripple performance, the device is often used in power supplies, power converters, battery chargers and other applications requiring high ripple current operation. In addition, its capacitance, voltage rating and wide operating temperature range make it ideal for automotive, industrial, aviation and military electronics. The UPJ1A392MHD aluminum electrolytic capacitor is also suitable for use in medical devices, as well as in consumer electronics such as radios, TVs, computers and mobile phones.

In conclusion, the UPJ1A392MHD aluminum electrolytic capacitor is a highly capable device designed for a wide range of applications. Its capacitance and voltage rating, combined with its low impedance and good ripple performance, make it suitable for a variety of applications, from automotive and industrial electronics to consumer electronics.
