The R41 series capacitors from Kemet are automotive grade, radial leaded, class Y2 metalized polypropylene film EMI suppression capacitors. These capacitors are constructed of multilayer metalized paper encapsulated and impregnated in self extinguishing material meeting the requirements of UL94 V-0 standard. It is used as electromagnetic interference (EMI) suppression filter in "line to ground" and "across the line" applications requiring Y2 / X1 safety classification. It is suitable for use in situations where failure of the capacitor could lead to danger of electric shock and not for use in "series with mains" type applications.
