Vishay’s new Low Profile Power Inductors key to space-saving for Portable Electronics

Non-Shielded and Shielded Devices Deliver Inductance Up to 100 µH in 1212, 1616, and 2020 Case Sizes

189

Vishay Intertechnology, Inc. on April 10, 2017, introduced two new series of low profile power inductors optimized for DC/DC conversion in portable electronics. Offered in compact 1212, 1616, and 2020 case sizes with low profiles down to 1.0 mm, Vishay Dale IFL and IFLS series devices deliver inductance up to 100 µH — values normally reserved for larger components.

With their small size, high inductance values, and frequencies up to 5 MHz, the devices released provide a space-saving solution for notebooks, desktop PCs, and servers; low profile, high current power supplies and point of load (POL) converters; and DC/DC converters for distributed power systems and FPGAs.

IFL and IFLS series devices feature a ferrite core with polyurethane enameled copper wire and an epoxy resin adhesive. The non-shielded IFL series offers typical DCR from 42 mΩ to 2460 mΩ and high rated saturation current to 7.5 A. The shielded IFLS series protects nearby components from magnetic radiation while providing typical DCR from 43 mΩ to 1730 mΩ and rated current to 3.8 A. All devices are RoHS-compliant and operate over a temperature range of -40 °C to +105 °C.
