R41B series capacitors are THB Grade IIIB, Class X1/Y2, 350VAC, 125°C (automotive grade) metallized polypropylene film EMI suppression capacitors. R41B is constructed of metallized polypropylene film, encapsulated with self-extinguishing resin, in a box of material meeting the requirements of UL 94 V-0. Automotive Grade devices meet the demanding Automotive Electronics Council's AEC–Q200 qualification requirements. Suitable for use in electromagnetic interference (EMI) suppression filter in line-to-ground and across-the-line applications, requiring Y2/X1 safety classification. Suitable for use in situations where failure of the capacitor could lead to danger of electric shock.
