The non-shielded SDR, semi-shielded SRN, and the shielded SRR and SRU inductors are offered in 3 mm, 6 mm, and 8 mm square footprints. These inductors have comparable performance and can be substituted for one another to test the effect of different levels of magnetic shielding. The next several pages will review a cross reference created by Bourns for users who would like to test the performance of comparable inductors with different levels of magnetic shielding.
