MPXB185K305H is a Class X2 safety capacitor rated for 305 VAC, designed for across-the-line applications in EMI filters and outdoor use. It has a capacitance of 1.8 µF with a dv/dt rating of 100 V/µs, dimensions of 32x33x18 mm, a lead spacing of 27.5 mm, and lead diameter of 0.8 mm. Constructed with metallized polypropylene film, it features a flame-retardant epoxy-coated case (UL94V-0) and lead-free tinned terminals. It meets UL/CSA, ENEC, and CQC safety standards with a dissipation factor ≤0.4% at 1 kHz, insulation resistance >3000 MΩ terminal-to-case after life testing, and operates from -40°C to +110°C. The capacitor is rated for 100,000 hours at 85°C hot-spot temperature and withstands 2050 VDC between terminals and case for 60 seconds.
