Commercial and automotive grade shield inductors in compact 2020 case size

09-03-2022 | Vishay | Passives

Vishay Intertechnology has expanded its IHLE series of low profile, high current inductors offering integrated E-field shields to reduce EMI with new commercial and Automotive Grade devices in the 5mm x 5mm x 3.4mm 2020 case size. The Vishay Dale IHLE-2020CD-51 and IHLE-2020CD-5A are the smallest devices on the market that lower costs and save board space by removing the requirement for separate board-level Faraday shielding.

The devices contain the electric and B field associated with EMI in a tin-plated copper integrated shield, offering up to -20dB of electric field reduction at 1cm (above the centre of the inductor) when the integrated shield is connected to ground. Featuring high-temperature operation to +155C and coplanarity of their four terminals within ≤100µm, the inductors are optimised for energy storage in DC-DC converters up to 3MHz and provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor.

Applications for the IHLE-2020CD-51 includes servers and desktop PCs, notebooks, high current POL converters, low profile, high current power supplies, FPGAs, and battery-powered devices. The AEC-Q200 qualified IHLE-2020CD-5A can be employed in automotive engine and transmission control units, LED drivers, instrumentation panels, entertainment/navigation systems, ADAS devices/sensors, and noise suppression for PWM-controlled motors.

Packaged in a 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the inductors offer high resistance to thermal shock, moisture, and mechanical shock and handle high transient current spikes without saturation. The devices are RoHS-compliant, halogen-free, and Vishay Green.
