The KXQ series is focused on smoothing the PFC output of OBC (on board charger), which is one of the key components of electric vehicles such as EVs and PHEVs that are expanding rapidly.
The KXQ series makes it possible to reduce the mounting area by increasing the capacitance
per unit and endurance at 105 ºC for 10,000 hours or more.
