Shielded and Semi-Shielded Series Ferrite Inductors

Vishay shielded IFDC series and semi-shielded IFSC series of wirewound, surface-mount ferrite inductors offer devices in 2020DE, 3232DB, and 5050HZ case sizes. Featuring improved performance at a lower cost than previous-generation ferrite solutions, the Vishay Dale inductors combine higher inductance and current ratings with lower DCR for computer and consumer applications. The IFDC-5050HZ, IFSC-2020DE-01, and IFSC-3232DB-01 match the performance of previous-generation ferrite solutions but with a 60% smaller size. The inductors offer enhanced performance compared to similar-sized devices, including higher operating temperatures and operating voltages.

The IFSC-2020DE-01 and IFSC-3232DB-01 feature 40% lower DCR, while the IFDC-5050HZ supports higher saturation currents. While other high-performance inductors typically offer a maximum inductance of 100 mH, the IFSC and IFDC series devices achieve significantly higher values. By utilizing efficient manufacturing techniques and a simple bobbin-style wirewound construction, the inductors provide improved quality and reliability at a three times lower cost. With the enhanced efficiency enabled by their low-loss ferrite core construction and low DCR, the devices are ideal for use as energy storage inductors in a variety of DC/DC conversion topologies found in consumer electronics and battery-powered devices. The IFSC and IFDC families make cost-effective solutions in differential LC filter topologies for noise suppression on power lines. The IFDC-5050HZ features a coil enclosed in an exterior magnetic material that contains stray flux, minimizing EMI and crosstalk to nearby components.
