CAP019DG-TL [Power Integrations]

CAPZero™ blocks current flow in the X capacitor safety discharge resistors when AC voltage is applied, reducing power loss to less than 5 mW at 230 VAC. When AC voltage is disconnected, it automatically discharges the X capacitor through series discharge resistors. This allows flexible X capacitor selection for optimized EMI filtering and reduced inductor costs without changing power consumption. The two-terminal design simplifies safety compliance and meets EuP Lot 6 requirements. The family includes 825 V and 1000 V voltage grades depending on surge requirements.
