Cornell Dubilier Film Paper Film Capacitors MPX684K305E

MPX684K305E is a metallized polypropylene film capacitor for X2 safety applications across the mains, rated for 305 VAC and operating from -40°C to +110°C. It has a capacitance of 0.68 µF with a dv/dt rating of 400 V/µs, dimensions of 18x22x12.5 mm, lead spacing of 15 mm, and lead diameter of 0.8 mm. The capacitor complies with UL/CSA, ENEC, and CQC safety standards for X2 class applications. It features a flame-retardant epoxy-filled case (UL94V-0), lead-free tinned terminations, and meets lifetime requirements of 100,000 hours at 85°C hot-spot temperature with ≤10% capacitance change. Terminal-to-terminal insulation resistance exceeds 30,000 MΩ at 100 VDC, and dielectric strength is 2050 VDC between terminals and case for 60 seconds. Self-inductance is less than 1 nH per mm of lead spacing and length.
