Shielded inductors lower costs and save space in high-current converters

The Vishay IHLE-2020CD-51 and IHLE-2020CD-5A inductors feature an integrated E-field shield for the reduction of EMI, enabling power-system designers to lower costs and save board space by eliminating separate board-level Faraday shielding.

These additions to the IHLE® series of low-profile, high-current inductors are housed in a 2020 case with dimensions of 5 mm x 5 mm x 3.4 mm. The case has an integrated tin-plated copper shield which provides up to -20 dB of electric field reduction at 1 cm above the center of the inductor when the shield is connected to ground. It gives excellent attenuation of EMI noise in high-current filtering applications up to the inductor’s self-resonant frequency. The shielded, composite construction of the IHLE-2020CD-51 and IHLE-2020CD-5A also limits buzz noise to very low levels. 

The IHLE-2020CD-51 is for commercial applications, and the AEC-Q200-qualified IHLE-2020CD-5A is for automotive applications.
