Available in 2525, 3232, and 4040 Case Sizes, Devices Provide -20 dB Electric Field Reduction at 1 cm
Vishay Intertechnology, Inc. on Jan. 16, 2017, 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-
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 a 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.
