Aluminum Electrolytic Capacitors have been around for decades and offer ultrahigh capacitance values in very small form-factors. UBT1K101MPD8 capcitors are a particular type of electrolytic capacitors pioneered by Jamicon, designed for more specialized applications. This article will explain the application field and working principle of the UBT1K101MPD8 capacitor.

UBT1K101MPD8 capacitors are a kind of aluminum electrolytic capacitors designed for use in electrical systems that require space-saving, reliability, and high capacitance. Typical applications include power supplies, audio systems, and motherboards. Its aluminum-based design optimizes power usage, provides stability, and minimizes heat. This type of capacitor features a low-impedance construction to ensure fast, reliable operation in a wide range of temperatures.

UBT1K101MPD8 has a capacitance range from 1,000 to 10,000µF with rated voltage of 10 to 25 VDC. It is a non-polarized and non-inductive capacitor with tolerance of ±20%. Apart from the standard cylindrical types, its case and lead configuration can be customized to meet customer requirements. This versatile capacitor is available in both standard- and high-temperature, high-humidity versions.

The aluminum electrolytic capacitor consists of two metal plates — an “anode” and a “cathode” — that are separated by a thin dielectric oxide film, typically referred to as the “electrolyte”. In the UBT1K101MPD8 capacitor, electrolyte is made up of aluminium-cased bipolar electrolytic capacitors and the dielectric film is an aluminium oxide layer. It also includes a tantalum case and a dedicated terminal for connection. The oxide film serves to equalize the electric field across the plates, which helps make the UBT1K101MPD8 capacitor more reliable and efficient in performance.

The working principle of any aluminum electrolytic capacitor is based on the electrolyte\'s capacity to store, transfer, and resist electric charges. When an electric field is applied to the capacitor, electrical energy is stored in the electrolyte as an electrostatic charge that accumulates on the oxide film\'s surface. This charge creates an opposing electric field that forms a barrier between the two metal plates, allowing for energy storage and transfer over a period of time. The electrical energy that is stored then converts into an opposing voltage that prevents the capacitor from discharging prematurely.

The UBT1K101MPD8 capacitor is also designed to provide high ripple current and low Ambient Temperature Operating Ranges. It has a temperature coefficient of less than 0.009 for capacitance and 0.02 for Equivalent Series Resistance (ESR). Its other features include high heat capacity, which ensures compatibility with high-frequency applications, and a low ESR for more reliable performance in a wide temperature range. Its low leakage current and extended shelf-life also provide for better long-term reliability.

Overall, UBT1K101MPD8 capacitors represent a reliable option for use in electrical devices with demanding requirements for capacitance and stability. With its low-impedance construction, high heat capacity, and extended shelf-life, UBT1K101MPD8 is suitable for applications like power supplies, audio systems, and motherboards. Additionally, its versatile case and lead configuration offers users the flexibility to customize the product for their specific needs.
