MXT105K305G20 is a 1.0 µF X2 class EMI/RFI suppression capacitor designed for harsh environment applications. The capacitor features a metallized polypropylene film construction encapsulated with self-extinguishing epoxy resin in a UL 94V-0 flame-retardant plastic case, providing robust performance across demanding conditions. It is rated for 305 Vac operation with an operating temperature range of -40°C to +110°C, a dissipation factor of 0.001 at 1 kHz, and demonstrates high stability with a THB rating of 1,000 hours at 85°C and 85% relative humidity. The capacitor exhibits self-healing properties and is suitable for across-the-line class X2 applications, making it ideal for power supply filtering, EMI suppression, and industrial equipment requiring reliable capacitive performance in harsh environments.
