Do not use these products in any Automotive
Power train or Safety equipment including Battery
charger for Electric Vehicles and Plug-in Hybrid.
Only Murata products clearly stipulated as
"for Automotive use" on its catalog can be used
for automobile applications such as Power train and
Safety equipment.
*: In case of use C0G char., DC630V product with
pulse voltage, be sure not to use with 10kHz and
less pulse or ripple voltage condition.
and these product are not suitable for commercial
power line voltage application, such as AC filter.
For those applications, be sure to use AC voltage
rating product.(GA2/GA3 series)
