[Al-cap] KVB Series | Snap-in type 105℃3000hrs. AEC-Q200 compliant for OBC

Jul. 21, 2022

KVB seriesKVB series is designed with enhanced vibration performance and we have achieved “AEC-Q200 compliant” for snap-in capacitors. KVB series is suitable for PFC output filter of OBC that is one of the key components of electric vehicle such as BEV or PHEV glowing rapidly in the automotive market.
Endurance is 105℃3,000hrs.
You could also select KVA series (105℃2,000hrs) or LVA Series (105℃5,000hrs) to meet your application life time.

Proposal for OBC related products

For OBC application, we have variety of products line up except KVB series.
Interleaved PFC

Electric vehicles are becoming part of the social infrastructure. Their key component, the bidirectional OBC (on-board charger), is expected to play an active role in standard home in the event of power outages due to disasters. The technical challenge is to realize a compact and lightweight OBC. Nippon Chemi-Con contributes to the downsizing and weight reduction of your application with our new generation of common mode coils, nonflammable Varistors, AEC-Q200 compliant aluminum electrolytic capacitors, and metal cap MLCC for DC-DC converters.
