UHD1H271MPD1TD

Aluminum Electrolytic Capacitors are among the most preferred options in the utilization of energy-storing components for electronic devices. UHD1H271MPD1TD is one of the commonly used versions in this category. Its field of application and working principle are detailed in this article.

Field of Application

UHD1H271MPD1TD is a high-quality aluminum electrolytic capacitor suitable for products that demand large capacitance. In fact, it can offer up to 271 milliFarads of capacitance, when using a common 10mm x 10mm size. This large capacitance makes the capacitor ideal for use in a variety of motor-driving, switchmode power converters/supplies, and consumer electronics. In particular, UHD1H271MPD1TD is the preferred choice for products like brushless DC motors, HID lamps, or anti-lock brakes, where a large capacitance is absolutely required.

Working Principle

UHD1H271MPD1TD comprises two aluminum plates soaked in an electrolyte solution, further enclosed by a thin insulating film. This electrical double layer acts as a capacitor; i.e., the energy gets stored in the electric field between the two plates. When a voltage is applied to the plates, the electrical charge moves, as a result of the difference in potential, leading to flow of current throughout the circuit. The main properties of these capacitors include their low equivalent series resistance (ESR), high capacity in terms of capacitance, and the ability to withstand large spikes in voltage.

The most significant feature of this type of capacitor is the excellent performance it offers in terms of self-healing property. In its normal state, the voltage applied to the capacitor is limited by the dielectric characteristics. On application of higher voltage, it causes fraying of the thin insulating film, eliminating the possibility of explosion. The frayed segments immediately heal with the help of the electrolyte solution, maintaining the capacitor in its original form. This increases the safety and the capability of the capacitor.

Points to Remember

Although UHD1H271MPD1TD offers excellent features and benefits, it is essential to take certain precautions while installing and using it. The board surface should be clean and must not come in contact with any moisture. Excessive current passing through the capacitor can damage its components and induce heating. During handling, high static charges must be taken care of, since it can cause serious damage to the material. It is thus very important to use suitable grounding tools and assembling equipment.

In conclusion, UHD1H271MPD1TD is an excellent aluminum electrolytic capacitor that is widely used in various applications demanding large capacitance. Its performance with respect to capacity, self-healing potential, and ESR makes it a preferable choice for various products. However, it is important to make sure that all precautionary measures are taken before and during its use.
