The 1.1 A current rating is the DC bias limit at which the self-heating from the 55 mOhm DCR keeps the temperature rise within the part's rated envelope — push beyond that and the inductance starts to roll off from core saturation, not just thermal runaway. Unshielded construction means the magnetic field from the wirewound coil radiates into the surrounding PCB area. In a power rail or DC-DC converter, that field can couple into nearby signal traces or sensitive analog sections — keep a ground plane under the part and maintain at least a 2–3 mm keep-out zone around the body to avoid unintended coupling into adjacent filter stages. The self-resonant frequency sits at 250 MHz, meaning the inductor behaves like a pure inductive element up to roughly a quarter of that frequency — above 60–80 MHz the parasitic capacitance starts to dominate, and the impedance rolls off. For switching regulators switching at 500 kHz to 2 MHz, this SRF gives plenty of headroom. ## NRND — sourcing reality for this part That means it is still available for existing BOM lines but is not the part to drop into a fresh layout — the manufacturer is winding down support.","metaTitle":"Taiyo Yuden LBC3225T1R0MR 1 µH Wirewound Inductor, 1.1 A","metaDescription":"Taiyo Yuden LBC3225T1R0MR 1 µH unshielded wirewound inductor, 1.1 A, 55 mOhm DCR, 1210 (3225 Metric) package.
