Vishay Unveils IHLE Integrated E-Field Shield Inductors

Applications for the IHLE-2020CD-51 will include servers and desktop PCs; notebooks; high current POL converters; low profile, high current power supplies; FPGAs; and battery-powered devices.

Vishay Intertechnology has extended its IHLE series of low profile, high current inductors featuring integrated E-field shields for the reduction of EMI with new commercial and Automotive Grade devices in the 5 mm by 5 mm by 3.4 mm 2020 case size.

Vishay IHLE E-Field The smallest such devices on the market, the Vishay Dale IHLE-2020CD-51 and IHLE-2020CD-5A lower costs and save board space by eliminating the need for separate board-level Faraday shielding.

The devices released 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 center 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 3 MHz and provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor.

Applications for the IHLE-2020CD-51 will include 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 will be used in automotive engine and transmission control units; entertainment/navigation systems; LED drivers; instrumentation panels; 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 IHLE-2020CD-51 and IHLE-2020CD-5A are RoHS-compliant, halogen-free, and Vishay Green.
