Murata Manufacturing has introduced the DE5 series of automotive safety-certified leaded disc ceramic capacitors for electric vehicle (EV) onboard chargers and other automotive power applications.
The capacitors have received X1/Y1 certification under IEC 60384-14, which defines safety requirements for capacitors connected to commercial power sources.
The certification covers withstand voltage and flame-retardant performance intended to reduce the risk of fire and electric shock caused by leakage current.
Safety-certified capacitors are used on ac power lines to suppress electrical noise and are also incorporated into EV onboard chargers. While Y2-class certification is commonly used for onboard charging applications, designs requiring greater voltage capability or additional safety margin may call for Y1-class components.
Compared with Murata’s existing DE6 series, the DE5 series increases the rated voltage from 300 Vac to 500 Vac. Its impulse withstand test voltage has also increased from 5 to 12 kV.
The higher voltage capability is intended to support onboard charger designs requiring greater electrical robustness and safety margin.
