【文字介绍】Vishay Intertechnology, Inc. announced 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 m to 167 m 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’ 4-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.
