Inductors feature integrated e-shields

The newly extended Vishay Dale IHLE series of low profile, high current inductors featuring integrated e-shields are in stock at New Yorker Electronics.

These integrated e-shields reduce EMI in new commercial and Automotive Grade devices.

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

These new inductors contain the electric and B field associated with EMI in a tin-plated copper integrated shield.

They provide up to -20dB of electric field reduction at 1cm (above the centre of the inductor) when the integrated shield is connected to ground.

They are packaged in a 100% lead (Pb)-free shielded, composite construction that reduces buzz to ultra-low levels.

It also demonstrates high resistance to thermal shock, moisture and mechanical shock.

The inductors are used for energy storage in DC/DC converters and high current filtering in such products as desktop PCs and servers, high current POL converters, low profile, high current power supplies and battery-powered devices.

They also have many automotive applications such as 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.

High temperature operation is up to +155 °C. The inductors are AEC-Q200 qualified and can handle high transient current spikes without saturation.

They are offered in a 5050 case size and have co-planarity of their four terminals within ≤ 100µm

They are RoHS-compliant, halogen-free, and Vishay Green

Samples and production quantities of the new IHLE devices are available now from New Yorker Electronics, with lead times of nine weeks for large orders.

As a franchise distributor for Vishay Dale, New Yorker Electronics supplies its complete line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
