NRND — plan the BOM migration now
The LBC3225T3R3MR: That means it is still available for existing production BOMs, but the manufacturer will not support new design-ins. Any new board layout should target a replacement inductor; for current builds, the part remains orderable through independent distribution while inventory lasts.
3.3 µH, 820 mA — the DC bias and loss budget
Rated 3.3 µH ±20% at 100 kHz test frequency. The 820 mA current rating is the DC current at which the inductance typically drops by 10% due to core saturation — the nominal is not the absolute-max. With a DCR of 95 mOhm, the I²R loss at 820 mA is about 64 mW; the 105°C temperature ceiling leaves headroom for self-heating in a 85°C ambient if the trace copper and via count around the pad are adequate.
160 MHz SRF — where the inductor stops being an inductor
Self-resonant frequency is 160 MHz. Above that point the parasitic capacitance between windings dominates and the impedance becomes capacitive. For a DC-DC converter switching at 2–4 MHz, the SRF is well clear of the fundamental and the first few harmonics; for RF bias-tee or filter applications, verify the operating band stays below 160 MHz with margin.
1210 footprint, unshielded — layout considerations
Being unshielded, the magnetic field extends beyond the component body — keep sensitive traces or other magnetics at least one part-width away to avoid coupling.
