Ferrite Inductors Soak Up EMI

The new LB series wound chip inductors have a special coating that reduces EMI radiation for applications in mobile communications equipment, notebook PCs, and disk drives. Produced in 0804 and 0806 sized packaging, the chips range in value from 1 to 100 µH and current ratings to 455 mA. The devices feature low DC resistance (0.09 to 4.5 ohms), depending on inductance value, a minimum Q of 10, and a minimum SRF of 100 MHz. Designed for use over the commercial temperature range (-25°C to +85°C), the inductors are suitable for reflow soldering and come packed in tape-and-reels for auto-insertion.
