Nippon Chemi-Con Developed LBK Series Lead Type Aluminum Electrolytic Capacitors with 44% Larger Capacitance for Automobile SRS Airbags
Nippon Chemi-Con has developed the LBK Series of large capacitance Lead Type Aluminum Electrolytic Capacitors for SRS airbags installed in automobiles.
The basic role of an aluminum electrolytic capacitor for airbag equipment is that of a backup power supply for actuating the airbag when the power supply from the battery is cut off due to an accident. Recently, the advent of multiple channels in airbag systems has increased the electric power necessary for actuating Automobile SRS Airbags, and aluminum electrolytic capacitors with larger capacitance are being demanded.
In addition, anticipating that airbag control units become smaller and electronic components are mounted more densely, Nippon Chemi-Con has developed and commercialized a series of products with capacitance that exceed the current LBG Series of aluminum electrolytic capacitors for airbag systems.
Technical Advantages
In order to realize larger capacitance, the LBK Series uses a high-magnification aluminum electrode foil with a larger capacitance per unit area compared to conventional products. In addition, the element storage efficiency has been improved by introducing features such as new electrolyte paper, thereby greatly increasing the foil area. This has led to a 44% larger capacitance compared to the existing series.
