KEMET Introduces AAR80 Aluminum Rectangular Capacitors designed for EV On-Board Chargers (OBC)

KEMET, part of the YAGEO Group and leading global electronic components supplier, announces its new AAR80 series, an AEC-Q200 qualified aluminum rectangular capacitor, designed for automotive applications. It offers high capacitance, good ripple current capability, and robust vibration resistance. Rated at 105°C, the AAR80 offers good volumetric efficiency in a shape that lends itself to stacking into modules. The large surface area of the aluminum case with stainless steel shell, allows for easy use with a heat sink.

KEMET’s Aluminum Electrolytic Snap-In capacitors have been widely used on OBC as DC-Link Capacitor for stabilizing the Output PFC DC voltage. This new Rectangular AAR80 series brings same performance with additional space saving.
