NICHICON CORPORATION has launched the UTH series of miniature aluminum electrolytic capacitors with long life (guaranteed for 5,000 hours at 105°C), to meet the demand for compactness and long life in the power supply field.
Overview and Development Background
In the market for server power supplies and switching power supplies, there has been a strong demand for more compact passive components, including capacitors, to improve surface power density. This is in addition to demand for more highly integrated circuits and high-density mounting of electronic components. Further, the thermal design of equipment is also becoming more sophisticated due to the miniaturization, high integration, and high-density mounting of equipment, and capacitors are required to have high reliability.
To meet these market needs, we have developed and launched a new series, the UTH series, which is smaller in size than the current UPT series (guaranteed for 5,000 hours at 105°C).
The UTH series is based on our accumulated technologies. It realizes high capacitance and miniaturization by utilizing a newly developed high-capacity electrode foil and newly developed sealing rubber. As a result, the UTH series is as much as 50% smaller in height and 52.4% smaller in volume than the current UPT series when comparing products rated to the same voltage and capacitance.
This product will contribute to more compact, lower-profile, space-saving circuit designs.
