DATASHEET Common-mode Chokes EV/EH series Common-mode Suppression Chokes Rated currents up to 5 A Approvals & Compliances 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 capacitors building an AC EMI suppression filter Technical specifications device. 250 VAC 50C Maximum continuous operating voltage 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 25C 3000 VAC, 60 sec, guaranteed Low magnetic leakage flux 2000 V, 50 Hz, 2 sec, factory test Sectional winding Temperature range (operation and storage) -25C to +100C (25/100/21) Flammability corresponding to UL 94 V-0 Standard foot print Measuring frequency 10 kHz 5 mA <16 H Broad range of available inductances and current 500 A >16 H <160 H ratings 50 A >160 H >16 mH Custom-specific versions 50 mV >16 mH <160 mH Inductance tolerance 30% Schaffner offers you also EMI measure- ment service Resistance Tolerance max. 15% 25C 20 m, 1 A to verify that your design will pass the required >20 m 200 m, 100 mA >200 m 2 V, 10 mA safety standards Electrical characteristics 25C 2C MTBF 40C/230 V (Mil-HB-217F) >5,000,000 hours 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 schematic2 EMC/EMI Products Schaffner Group Datasheets 09 Dec 2021 Choke selection table EH choke Buy EV choke Buy L nominal DC resistance Rated current Weight (EH) (EV) (30%) R I (50C) mH m A g EH20-0.3-02-33M EV20-0.3-02-33M 33 1780 0.3 10 EH20-0.5-02-18M EV20-0.5-02-18M 18 725 0.5 10 EH20-0.8-02-5M6 EV20-0.8-02-5M6 5.6 245 0.8 10 EH20-1.0-02-3M9 EV20-1.0-02-3M9 3.9 168 1.0 10 EH20-1.2-02-3M3 EV20-1.2-02-3M3 3.3 127 1.2 10 EH20-1.5-02-1M8 EV20-1.5-02-1M8 1.8 72 1.5 10 EH20-2.0-02-0M8 EV20-2.0-02-0M8 0.82 38 2.0 10 EH24-0.5-02-44M EV24-0.5-02-44M 44 1250 0.5 18 EH24-0.8-02-18M EV24-0.8-02-18M 18 438 0.8 18 EH24-1.0-02-10M EV24-1.0-02-10M 10 244 1.0 18 EH24-1.5-02-4M5 EV24-1.5-02-4M5 4.5 116 1.5 18 EH24-2.0-02-2M5 EV24-2.0-02-2M5 2.5 62 2.0 18 EH24-3.0-02-1M2 EV24-3.0-02-1M2 1.2 29 3.0 18 EH24-4.0-02-0M5 EV24-4.0-02-0M5 0.5 16 4.0 18 EH28-1.0-02-75M-X 75 880 1.0 31 EH28-1.0-02-36M EV28-1.0-02-36M 36 591 1.0 31 EH28-1.5-02-27M-X EV28-1.5-02-27M-X 27 282 1.5 31 EH28-1.5-02-20M EV28-1.5-02-20M 20 282 1.5 31 EH28-2.0-02-15M-X 15 196 2.0 33 EH28-2.0-02-11M EV28-2.0-02-11M 11 162 2.0 31 EH28-3.0-02-9M0-X EV28-3.0-02-9M0-X 9 115 3.0 31 EH28-3.0-02-5M0 EV28-3.0-02-5M0 5 79 3.0 31 EH28-4.0-02-3M5-X 3.5 52 4.0 31 EH28-4.0-02-2M3 EV28-4.0-02-2M3 2.3 40 4.0 31 EH28-5.0-02-1M1 EV28-5.0-02-1M1 1.1 27 5.0 31 EH35-1.0-02-90M EV35-1.0-02-90M 90 628 1.0 70 EH35-2.0-02-20M EV35-2.0-02-20M 20 150 2.0 70 EH35-3.0-02-10M EV35-3.0-02-10M 10 72 3.0 70 EH35-4.0-02-5M0 EV35-4.0-02-5M0 5 53 4.0 70 EH35-5.0-02-3M6 EV35-5.0-02-3M6 3.6 33 5.0 70 All wires rated 130C or higher.
