Shielded inductor delivers -20dB electric field reduction at 1cm
Available in the 2525, 3232, and 4040 case sizes, the Vishay Dale IHLE-2525CD-51, IHLE-3232DD-51, and IHLE-4040DD-51 contain 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 centre of the inductor) when the integrated shield is connected to ground. By eliminating the need for expensive board-level Faraday shielding to lower EMI, the devices reduce costs and save board space.
Featuring high temperature operation to +155 °C and coplanarity of their four terminals within 100µm, the inductors are optimized for energy storage in DC/DC converters and high current filtering. The devices exhibit a typical DCR from 1.55mΩ to 167mΩ and a wide range of inductance values from 0.22µH to 47µH. The devices provide rated currents to 36.0A and handle high transient current spikes without saturation.
