Vishay Expands its Low profile, High Current E-Shield Reduced EMI Inductor Series

Vishay Intertechnology, Inc. expanded its IHLE® series of low profile, high current inductors featuring integrated e-shields for the reduction of EMI with new commercial and Automotive Grade devices in the 5050 case size.

The Vishay Dale IHLE-5050FH-51 and IHLE-5050FH-5A lower costs and save board space by eliminating the need for separate board-level Faraday shielding.

The devices released today contain the electric and B 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 centre of the inductor) when the integrated shield is connected to ground. Featuring high-temperature operation to +155 °C and coplanarity of their four terminals within ≤ 100 µm, the inductors are optimized for energy storage in DC/DC converters up to 2 MHz and provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor.

Applications for the IHLE-5050FH-51 will include desktop PCs, and servers; high current POL converters; low profile, high current power supplies; and battery-powered devices. The AEC-Q200 qualified IHLE-5050FH-5A will be used in automotive engine and transmission control units, diesel injection drivers, noise suppression for motors, windshield wipers, power mirrors and seats, entertainment/navigation systems, heating and ventilation blowers, and LED and HID lighting.

Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz 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 IHLE-5050FH-51 and IHLE-5050FH-5A are RoHS-compliant, halogen-free, and Vishay Green.
