DATASHEET Common-mode Chokes EV/EH series Common-mode Suppression Chokes Rated currents up to 5 A Approvals Broadband attenuation characteristics Low magnetic leakage flux UL rated materials RoHS compliant Common-mode suppression chokes are mainly used to filter noise on AC power lines. Noise on commercial power lines could enter the equipment and disturb the proper function. Noise generated by the equipment for example from switch mode power supplies need to be filtered and the spread of such generated noise need to be suppressed. Common- mode suppression chokes together with line bypass Technical specifications capacitors building an AC EMI suppression filter device. Maximum continuous operating voltage 250 VAC @ 50°C Features and benefits Operating frequency DC to 400 Hz Rated currents 0.3 to 5 A Rated currents up to 5 A Overcurrent 1.5x Inominal for 1 minute, once per hour Compact and light weight winding-to-winding @ 25°C 3000 VAC, 60 sec, guaranteed 2000 V, 50 Hz, 2 sec, factory test Low magnetic leakage flux Temperature range (operation and storage) -25°C to +100°C (25/100/21) Sectional winding Flammability corresponding to UL 94 V-0 Standard foot print Test conditions Broad range of available inductances and current Measuring frequency 10 kHz; 5 mA <16 μH; ratings 500 μA >16 μH <160 μH; Custom-specific versions 50 μA >160 μH >16 mH; 50 mV >16 mH <160 mH Schaffner offers you also EMI measure- ment service Inductance tolerance ±30% to verify that your design will pass the required Resistance Tolerance max. ±15% @ 25°C; ≤20 mΩ, 1 A; safety standards >20 mΩ ≤200 mΩ, 100 mA; >200 mΩ ≤2 V, 10 mA Electrical characteristics @ 25°C ±2°C Typical applications Input filters for switch mode power supplies Filters to reduce leaking noise TVs, VCRs, multimedia and audio equipment Office automation, communications and other electronic devices Electric ballast AC/AC converters Typical electrical schematic
