Shielded Inductors Free Up Board Space

Allowing components to be mounted closer together on pc boards, the SMRF 5025S series inductors integrate shielding into the inductor via a sleeve of magnetic material wrapped over the coil. The shielding is said to present less than 2% coupling as opposed to distributed gap materials that typically yield 3% to 5%. The inductors are available in values from 10 to 10,000 µH and in incremental current ratings from 3,900 to 54 mAdc (based on a 35°C temperature rise at an ambient temperature of 90°C), with custom designs also available for user-specific applications. Operating temperature range is from -55°C to 125°C. Pricing in production quantities is $0.81 each. GOWANDA ELECTRONICS, Gowanda, NY. (716) 532-2234.
