VSH Vishay Intertechnology

Vishay Intertechnology, Inc. (NYSE: VSH) today expanded its IHLE® series of low profile, high current inductors featuring integrated E-field shields with a new second-generation Automotive Grade device in the 10 mm by 10 mm 4040 case size. Offering an improved shield design over previous-generation solutions, and polarity marked for more consistent EMI performance, the Vishay Dale IHLE-4040DDEW-5A lowers costs and saves board space by potentially eliminating the need for separate board-level Faraday shielding.

Compared to traditional composite inductors, the device released today contains the electric and magnetic fields associated with EMI in a tin-plated copper integrated shield. When the shield is connected to ground, the IHLE-4040DDEW-5A provides up to 20 dB reduction in radiated noise interference, and a further 6 dB reduction in magnetic flux leakage to minimize crosstalk to nearby board components. The inductor features continuous high temperature operation to +155 °C and improved operating and isolation voltage ratings of 75 V and 100 V, respectively.

The IHLE-4040DDEW-5A power inductor is optimized for energy storage in switch mode power supplies and provides excellent noise attenuation when used as a DC power line choke. AEC-Q200 qualified, the device is designed for filtering and DC/DC conversion in entertainment / navigation systems; LED drivers; and noise suppression for motors, automotive domain control units (DCU), and other noise-sensitive applications.

Packaged in a 100% lead (Pb)-free, magnetically shielded, iron alloy encapsulant, the IHLE-4040DDEW-5A offers high resistance to thermal shock, moisture, and mechanical shock from the additional mounting support provided by its two shield terminals. The inductor is RoHS-compliant, halogen-free, and Vishay Green.
