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. Key Features Capacitance: 100nF (0.1µF / 104 code) Rated Voltage: 275VAC Safety Class: X2 suppression capacitor Tolerance: ±10% (“K” tolerance code) Operating Temperature: -40°C to +110°C Through-hole radial package Self-healing polypropylene film construction High surge and impulse voltage capability Flame-retardant and safety-certified design Suitable for EMI noise suppression across AC mains Typical Applications AC line filtering SMPS input filtering Appliance EMI suppression Motor noise suppression Snubber and interference suppression circuits Across-the-line mains applications Part Marking Breakdown X2 → Safety capacitor class for across-the-line AC applications 104 → 100nF capacitance code K → ±10% tolerance 275VAC → Rated continuous AC voltage
