[Al-cap] MHU series that realized longer lifetime and high vibration resistance. AEC-Q200 compliant.
Oct. 16, 2021
Car sharing is a major factor in the MaaS (Mobility as a Service) .With car sharing become widely used, we are expecting the car will be using under more severe environments in the future.
In addition, Infrastructure such as 5G base station is also required longer lifetime in high temperature.
Nippon Chemi-Con has developed aluminum electrolytic capacitor SMD type with new generation platform in order to achieve endurance for severe conditions.

Key Technologies and Advantage
- Sealing by Resin*1
Evaporation of electrolyte is a main degradation factor of aluminum electrolytic capacitors,
The electrolyte evaporation can be suppressed by new sealing method using rubber and resin.
*1: Patent Pending.
- New structure
Realized innovative high vibration resistance with using vibration resistance base plate and sealing by rubber and resin.
