Application Field and Working Principle of UPJ1C182MHD6TN

The UPJ1C182MHD6TN is an aluminum electrolytic capacitor, a passive component widely used in various electrical and electronic circuits, mainly for energy storage, signal bypass, and filters for analog circuits, power supplies, etc. Its shape is cylindrical, with two lead wires, and the surface is printed with capacitance, rated voltage and the brand logo.

Application Field of Aluminum Electrolytic Capacitor

Aluminum electrolytic capacitor has a large capacity, a wide range of operating voltages and frequencies, less space, reliably and stable performance, long working life and a low price. It is mainly used in a variety of electronic circuits, including:

• Audio-frequency filter and bypass.
• The DC stability and de-noising of switching power supply.
• Circuit timing, interference filtering and energy-storing of Wireless Equipment.
• Tuning and filtering of RF circuits.
• Smoothing circuit of current supply.
• Suppressing transient pulse.

Working Principle of the UPJ1C182MHD6TN

This capacitor consists of two metal electrodes, an electrolyte and an insulating paper separating them. When a voltage is applied to both of the capacitor\'s electrodes, a layer of oxide film is formed on the anode, creating a dielectric that produces a positive charge at the anode. This causes current to be blocked and charge accumulation to occur. The size of the charge created is based on the capacitance of the electrodes, the applied voltage and the nature of the electrolyte.

There are two types of Aluminum electrolytic capacitor dielectric in commercial use, aluminum oxide and tantalum pentoxide. The former has a higher distributed capacitance but exhibits poor resistance to high temperatures, while the latter is more stable at high temperatures but has a lower distributed capacitance. However, its superior performance at high temperatures make it suitable for high power circuits and by running at a temperature lower than its limit, the UPJ1C182MHD6TN Aluminum Electrolytic Capacitor can easily meet the requirements of most circuits.
