Aluminum electrolytic capacitors, also known as wet aluminum capacitors, are generally non-solid electrolyte capacitors that use electrolyte in the form of a paste or liquid to separate the charge carriers. The capacitor\'s case is generally formed of two metal plates, one of which is the anode and the other is the cathode, separated by varying distances depending on the device type. The spiral shape of the plates in an aluminum electrolytic capacitor usually feature a layer of insulating material, which can be paper, plastic, or a ceramic material, to contain the electrolyte. The aluminum foil that forms the plates of the capacitor can be etched or punched to form the many finger-like structures which serve to increase the surface area of the plates.

The UPJ1K100MED1TD series of aluminum electrolytic capacitors is designed for use in a variety of applications, including DC Link, energy storage, biomedical measurement, LCD/LED backlight, and high-frequency power supply. Depending on the specific application, different device configurations may be necessary, such as with its large ripple current capability, its low equivalent series resistance, and its wide capacitance range. Regardless of the application, the UPJ1K100MED1TD aluminum electrolytic capacitor series offers the same general working principle.

A basic understanding of how aluminum electrolytic capacitors work is relatively simple. When powered up, an electric field is created between the plates, which causes electrons to migrate through the liquid electrolyte past the insulation medium. This migration of charge helps to form the electrical connection between the plates and the device, allowing it to act as a charged storage device. This is known as capacitive compensation, and it is essential for the functioning of an aluminum electrolytic capacitor.

The UPJ1K100MED1TD series aluminum electrolytic capacitors are specifically designed with an expanded operating temperature range to handle higher ripple currents and higher than normal temperature ranges that other aluminum electrolytic capacitors may not be able to handle. Additionally, the UPJ1K100MED1TD series aluminum electrolytic capacitor is designed with a majority of its bleed voltage occurring within the range of +10% to -33%, as compared to other aluminum electrolytic capacitors that typically feature a bleed voltage of +15% to -25%. Furthermore, the circular shape of the device allows for easy installation and offers superior heat dissipation due to its increased surface area.

In general, aluminum electrolytic capacitors are well-suited for use in many applications, including energy storage, DC link, biomedical measurement, and LCD/LED backlights, depending on the specific configuration of the device. The UPJ1K100MED1TD series, in particular, stands out due to its extended temperature range, low equivalent series resistance, wide capacitance range, and increased surface area. These features combine to create a greatly enhanced capacitor that provides superior current handling capabilities and long-term stability under varying temperatures and application workloads.
