Vishay Intertechnology Low-Profile, High-Current Inductor Lowers Costs and Saves Space With Integrated E-Shield

Vishay IHLE-4040DC-5A

Vishay Intertechnology introduced a new automotive-grade low-profile, high-current inductor featuring an integrated e-shield for reduction of EMI in the compact 4040 case size. Lowering costs and saving board space in automotive and other applications by eliminating the need for separate board level shielding for the inductor, the Vishay Dale IHLE-4040DC-5A contains 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. In addition, the 4-terminal connection (two ground connection points for the shield) provides extra vibration performance for under-the-hood and chassis mounted electronic circuits.

Featuring high-temperature operation to +155 °C and coplanarity of its four terminals of < 100 µm, the AEC-Q200-qualified device released today is optimized for energy storage in DC/DC converters and high-current filtering for automotive engine and transmission control units, diesel injection drivers, noise suppression for motors, windshield wipers, power mirrors and seats, and HID lighting.

Built on Vishay's IHLP® technology, the IHLE-4040DC-5A features high efficiency with max DCR from 1.66 mΩ to 178 mΩ and a wide range of inductance values from 0.47 µH to 47 µH. The device provides rated currents to 30 A and handles high transient current spikes without saturation. Packaged in an RoHS-compliant, 100% lead (Pb)-free shielded construction, the inductor offers high resistance to thermal shock, moisture, mechanical shock, and vibration.
