C&D Technologies has introduced its 5000 series of surface-mount common mode chokes. The series provides line filtering of power converters, reducing unwanted common mode noise in EMC sensitive applications. This series offers inductance values ranging from 0.47 mH to 4.7 mH and a DC current rating of up to 700 mA. Able to attenuate at frequencies of up to 100 MHz, these devices are suited for use in low current DC input switching power supplies and telecom applications. Dimensions of 7.0 mm × 5.9 mm × 4.4 mm and an industry standard pad layout facilitate the design-in of series parts into existing applications and to new designs. Operating temperature range is -40°C to +85°C.
