Vishay Intertechnology, Inc. introduced a new automotive-grade low-profile, high-current inductor featuring an integrated e-shield for reduction of EMI in the compact 4040 case size. Lowering costs and saving board space in automotive and other applications by eliminating the need for separate board-level shielding for the inductor, the Vishay Dale IHLE-4040DC-5A contains the electric 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. In addition, the four-terminal connection (two ground connection points for the shield) provides extra vibration performance for under-the-hood and chassis-mounted electronic circuits.
