Application Field

The UKL2A101MHD capacitor is ideal for high frequency applications such as on-board phone chargers and electronic devices. It can also be used in power converters and motor drives due to its high ripple charge/discharge current and low series equivalent resistance. This capacitor is also suitable for AC/DC converters, thyristor soft starters, sound small amplifiers, DC/DC converters, voltage-stabilized power supply, and UPS applications.

Furthermore, the UKL2A101MHD capacitor can be used in automotive applications such as engine control, instrumentation, electric/hybrid vehicles, and energy-saving systems due to its low equivalent series resistance (ESR) and high surge withstand capability. This capacitor is also suitable for aerospace and defense applications such as satellite power systems, weapon trigger, navigational systems, and so on.

Working Principle

The UKL2A101MHD capacitor utilizes aluminum oxide film and an electrolyte to achieve its capacitance. This capacitor is composed of two electrodes separated by an electrolyte, a cathode and an anode. The anode is typically composed of aluminum foil and an insulating paper, and the cathode is usually composed of mica paper and an electrolyte. When current flows through the capacitor, electrons are drawn out of the anode through the insulating paper, and then recombine at the cathode, which establishes the capacitance.

In its working principle, the UKL2A101MHD capacitor also utilizes a polarized electrolytic. This type of electrolyte has a higher oxidation potential than the anode, which allows it to carry more charge and provides higher capacitance. Additionally, the capacitor also contains a solid electrolyte which is a combination of aluminum oxide and solvent. This solid electrolyte increases the capacitor’s capacitance by reducing its equivalent series inductance.

The UKL2A101MHD capacitor also utilizes a sealed case construction, which is designed to prevent corrosion and reduce high frequency power losses. In addition, the capacitor uses heat-resistant technology to maintain stability even in high temperature applications. This ensures that the capacitor will perform up to maximum efficiency in its selected application.
