NICHICON Launches Miniature Aluminum Electrolytic Capacitors with Long Life

24.10.2023
Reading Time: 2 mins read

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

Nichicon Develops High Voltage 150C Film Capacitors using Sabic High-Heat Foil

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).

Features

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.

Key Specifications

  • Rated voltage range :400 to 450V
  • Rated capacitance range :47 to 200μF
  • Category temperature range:-40 to 105℃
  • Product dimensions :φ16×20Lto φ18×40L(10 Sizes)
  • Life : 5000 hours guaranteed at 105°C(Rated ripple current superimposed)
  • Terminal shape :Lead type
