Only second half of that statement is true. It should be apparent that, since the current through both series inductors is the same, the current rating does not change. Upvote 0 Downvote

Current Rating = The maximum number of amps which can flow through the device before it is damaged. JimB Upvote 0 Downvote

Click to expand... It depends on their ratings - if one 300nH is the same current rating, then two in series will be as well. Upvote 0 Downvote

K kewping New Member Jul 6, 2022 #11 Thank you. I am using 300nH (2222SQ-301_E), so the Irms value is 3.7. so two 300nH in series, is also 3.7 https://4donline.ihs.com/images/VipMasterIC/IC/COLC/COLC-S-A0013855760/COLC-S-A0013956462-1.pdf?hkey=6D3A4C79FDBF58556ACFDE234799DDF0 Upvote 0 Downvote
