Vishay Intertechnology releases second-generation automotive grade IHLE inductor with integrated EMI shield in 4040 case size

07 June 2024

Vishay Intertechnology, Inc. has 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 electromagnetic interference (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 contains the electric and magnetic fieldsSource: Vishay Intertechnology, Inc.Source: Vishay Intertechnology, Inc. 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.

Samples and production quantities of the IHLE-4040DDEW-5A are available now, with lead times of 16 weeks.
