SMT Inductors Weed Out EMI

Employing what is described as a powerful magnetic shield, the DR331-7-8-9 series surface-mount inductors promise reliable EMI protection to designers of high-frequency filtering circuits. The inductors also address space concerns with an open-frame design that yields seated profiles as low as 2.92 mm. Inductance values range from 1 to 10,000 µH with dc resistances from 0.04? to 32.8? maximum over a maximum current rating from 3A to 20 mA. Operating temperatures range from ?40°C to +130°C and all materials meet UL 94V-0 requirements. Prices start at $0.39 . DATATRONIC DISTRIBUTION INC., Romoland, CA. (888) 889-5391.
