Nippon Chemi-Conhas developed three Series of snap-in type aluminum electrolytic capacitors for automotive OBCs (on-board chargers). These Series meet the vibration resistance requirements of AEC-Q 200, the standard for automotive electronic components.
In recent years, with the increase in driving range and popularization of EVs and PHEVs, aluminum electrolytic capacitors for input voltage filtering used in automotive OBCs are required to have higher capacitance and reliability. Against this backdrop, we have been developing products for automotive OBCs with the aim of further improving the performance of the existing ultra-small Series.
The three newly developed Series all have a rated voltage of 450V. The guaranteed endurance of the KVA Series is 2,000 hours at 105C, the KVB Series is 3,000 hours at 105C, and the LVA Series is 5,000 hours at 105C.
We have achieved high reliability compliant with AEC-Q 200 standards while maintaining basic performance equal to or higher than that of conventional products by selecting appropriate material and adopting a proprietary vibration-resistant design.
