The X2-104K-275VAC is an X2-class safety film capacitor commonly used for EMI/RFI suppression across AC mains lines in power supplies, appliances, chargers, and industrial equipment. It is designed to safely operate directly across line-to-neutral AC connections and withstand voltage surges and transients on the mains.
