Working Principle

An aluminum electrolytic capacitor is a type of capacitor with an electrolyte between two aluminum foils. The electrolyte is an paste made of metal oxide, which can accept charged ions and store the charge. The metal oxide is usually a mixture of polymers, such as polyesters or polypropylene oxide, and can have a variety of additives. This combination ensures that the capacitors are relatively stable and free from moisture or corrosion.

The UKW1A153MHD is a radial aluminum electrolytic capacitor. The construction of this type of capacitor is a radial wrap of both aluminum foil and electrolyte. The structure is sealed with a rubberized sleeve and capped with a plastic cover. As the electrical field charges the metal oxide, ions from the electrolyte are attracted to the edges of the aluminum foils, creating a high quantity of local charge carriers that oppose the initial electric field. This produces a very high capacitance for its size.

The UKW1A153MHD capacitor has a rated voltage of 100V and is capable of withstanding surge voltages of up to 125V. It also has a temperature range of –25 to +105°C, and a tolerance of ±20%. This makes it suitable for a wide range of applications, from automotive to industrial and medical equipment.

Conclusion

The UKW1A153MHD is a high-performance aluminum electrolytic capacitor suitable for use in a wide variety of applications. It has low equivalent series resistance, high ripple current, long lifetime, high temperature resistance and excellent frequency response. This makes it an ideal choice for power filter and DC/DC converter applications. It is a reliable and cost-effective capacitor that is sure to meet the needs of many different applications.
