What this 10 µH wirewound does in a power rail
The LBC3225T100MR is a 10 µH unshielded wirewound inductor in the standard 1210 (3225 Metric) footprint, rated for 540 mA continuous current with a DC resistance of 133 mOhm. Its self-resonant frequency of 23 MHz means it behaves as an inductor well into the low-MHz switching range — suitable for DC-DC converter output filters or input pi-filters where the ripple frequency stays below that point.
