MALVERN, PA --- Vishay Intertechnology, Inc. introduces a commercial version of its popular Automotive Grade IHLE series of low profile, high current inductors featuring integrated e-shields for EMI reduction. Available in the 2525, 3232, and 4040 case sizes, the Vishay Dale IHLE-2525CD-51, IHLE-3232DD-51, and IHLE-4040DD-51 contain the electric field associated with EMI in a tin-plated copper integrated shield, providing up to -20 dB of electric field reduction at 1 cm (above the center of the inductor) when the integrated shield is connected to ground. By eliminating the need for expensive board-level Faraday shielding to lower EMI, the devices reduce costs and save board space.
Featuring high temperature operation to +155 °C and coplanarity of their four terminals within ≤ 100 µm, the inductors released today are optimized for energy storage in DC/DC converters and high current filtering. Applications include notebooks, desktop PCs, and servers; high current point-of-load converters; graphics cards; DC/DC converters for distributed power systems and FPGAs; and telecom infrastructure.
Built on Vishay Dale IHLP® technology, the IHLE-2525CD-51, IHLE-3232DD-51, and IHLE-4040DD-51 feature high efficiency with typical DCR from 1.55 mΩ to 167 mΩ and a wide range of inductance values from 0.22 µH to 47 µH. The devices provide rated currents to 36.0 A and handle high transient current spikes without saturation.
Packaged in an RoHS-compliant, 100 % lead (Pb)-free shielded construction, the inductors offer high resistance to thermal shock, moisture, and mechanical shock. In addition, devices' four-terminal connection (two ground connection points for the shield) provides high vibration performance for on-engine and chassis-mounted electronic circuits. The devices are halogen-free and Vishay Green.
Samples and production quantities of the new IHLE devices are available now, with lead times of 10 to 12 weeks for large orders. Pricing for U.S. delivery only ranges from $0.50 to $0.75 per piece in 10,000-piece quantities.
