Miniaturized Snap-In Aluminum Electrolytics Rated for 5,000 Hours at 105°C

Nichicon Corp. has developed a family of miniaturized snap-in aluminum electrolytic capacitors with a long lifespan (5,000 hours at 105°C) for ac-dc power supplies, which have been advancing in terms of miniaturization and efficiency in recent years.

Demand for miniaturization and space-saving in ac-dc power supplies for servers and similar applications has been strong in recent years as internal space decreases due to circuit integration. Meanwhile, the internal temperature of power supplies is trending upwards. Under these conditions, there is demand for the large aluminum electrolytic capacitors used in power supply smoothing circuits to be miniaturized and made highly reliable (long lifespan).

To meet these demands, Nichicon reduced the size (maximum volume reduction of 28%) of the current LGX series (5,000 hours at 105°C) to develop the smallest product on the market that meets these specs.

To achieve miniaturization, Nichicon employs a newly developed high-capacitance aluminum electrode foil as the main material for this product. It also incorporates electrolytic paper optimized for electrolyte retention to achieve a long lifespan. Employing this product in set devices can contribute to miniaturization.
