Most inductors are not just some Henry-s, but also have some R-s and C-s (or Q-s). So using a simple spec sheet that gives you the inductance can possibly lead you astray. In simple circuits it may work, in critical circuits it may not. Good luck, Ahne. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Monday, July 27, 2015 9:03 AM To: [log in to unmask] Subject: [TN] Obsolete Multilayer Ferrite Inductor replacement? Hi All, We have a board here that uses a Multilayer Ferrite Chip Inductor from Murata that has gone obsolete. It's PN# CS321613-330. Murata decided to quit making it because according to the obsoleting notice they weren't selling many of these and not making any money: http://www.bourns.com/data/global/pdfs/IC1320_CS321613_POM.pdf So I've been looking for a replacement. I found a few out there, it needs to be a 1206, but I'm not an electrical guy, so I can't really make the call. Can any of you look at these and have an idea whether or not they would work? Below are the ones I found: AIML-1206-330 IC1206A33R-10 CL321611T-R33K-N Steve -- This email and any attachments are only for use by the intended recipient(s) and may contain legally privileged, confidential, proprietary or otherwise private information.
