ULD1A331MPD1TD

Aluminum electrolytic capacitors, sometimes referred to as "aluminum electrolytics", are capacitors with Aluminum electrolytic anodes and electrolyte conduction medium. This kind of capacitors has a wide range of uses, such as decoupling, filtering, compensation, energy storage, and so on, in the electronic circuits, and its application field includes power electronics, consumer electronics, automotive electronics, and medical electronics, etc.

The ULD1A331MPD1TD is a type of miniaturized aluminum electrolytic capacitor, it is widely used in circuit design for its high capacitance density, high ripple current capability and small physical size. The capacitance range of ULD1A331MPD1TD can be up to 330μF, and its operating temperature range is from -55℃ to +125℃.

The basic principle of ULD1A331MPD1TD is to utilize the capacitance generated by the Aluminum electrode and electrolytic anode. When a certain voltage is applied between the two electrodes, current will flow from the anode to the cathode in a liquid medium, which will form an electric double-layer capacitor, and a certain capacitance is produced between them. The more the number of double layers formed, the larger the capacitance.

The ULD1A331MPD1TD aluminum electrolytic capacitor is of a cylindrical structure, with length-to-diameter ratio of 5 to 6. The capacitor is filled with a liquid electrolyte to improve the contact between the electrolytic aluminium anode and the cathode, improve the electrochemical polarization characteristics, and further increase its capacitance. The main components of the capacitor are a positive and negative aluminum electrodes, separator, and a flux. The positive aluminium electrode in the capacitor is usually made with an anodic oxidation layer and a conductive oxide layer, which makes it possible for the capacitor to reach high capacitance value.

The ULD1A331MPD1TD capacitor is widely used in circuit design, mainly for filtering, smoothing and DC blocking, carrying high ripple current. It is also widely used in power electronics equipment, consumer electronics products, motor drives, medical equipments, automotive electronics and other industry applications, to meet the need for high reliability, high voltage, high capacitance value and long life.
