Vishay’s New Advanced Automotive Grade Low-Profile, High-Current Inductors Integrates E-Shield to Lower Costs and Save Space

Vishay Intertechnology announces expansion of its IHLE series of low-profile, high-current inductors featuring integrated e-shields for reduction of EMI with new Automotive Grade devices in the 2525, 3232, and 4040 case sizes.

The new Vishay Dale IHLE-2525CD-5A, IHLE-3232DD-5A, and IHLE-4040DD-5A touts to lower costs and save board space by eliminating the need for separate board-level Faraday shielding.

The devices 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.

In addition, the devices’ 4-terminal connection (two ground connection points for the shield) provides high-vibration performance for on-engine and chassis-mounted electronic circuits.

Built on Vishay Dale IHLP technology, the new series 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. The devices are halogen-free and Vishay Green.

Key Applications include

Featuring high-temperature operation to +155 °C and coplanarity of their four terminals within ≤ 100 µm, the AEC-Q200-qualified inductors released today are 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, entertainment / navigation systems, and HID lighting.
