en.Wedoany.com Reported - Nichicon (Japan) has announced the development and market launch of the "UTK Series," a small lead-type aluminum electrolytic capacitor for AI server power supplies. By optimizing the electrolytic paper specifications, this product achieves increased capacity while maintaining high withstand voltage characteristics, meeting the growing demand for high withstand voltage guarantees.

In recent years, the proliferation of generative AI and large-scale language models has driven the rapid development of AI servers. These devices are equipped with a large number of high-performance GPUs, exhibiting trends toward high density and high power consumption. Meanwhile, the expansion of cloud services and automation demands has led to a sharp increase in market demand.

AI server power supplies have high output power, requiring capacitors to withstand long-term continuous operation under high loads. Consequently, the market demand for products with high withstand voltage and high reliability continues to rise. In response to this background, Nichicon has developed the "UTK Series," a small lead-type aluminum electrolytic capacitor guaranteed for 105°C and 5000 hours with high withstand voltage.

Compared to the existing "UCY Series," the new series offers up to a 100% increase in electrostatic capacitance, up to an 81.6% increase in allowable ripple current, and adds a 475V rated voltage option.

The series has a rated voltage range of 475 to 500V, a rated electrostatic capacitance range of 65 to 160μF, a category temperature range of -40 to 105°C, and is available in 10 sizes. Both samples and mass production can be accommodated, with a supply system planned at 100,000 units per month, manufactured at Nichicon Ohno.
