100 µH wirewound in a 1210 footprint
The Taiyo Yuden LBC3225T101MR is a 100 µH unshielded wirewound inductor in a 1210 (3225 Metric) surface-mount package. It is part of the LB, C Type series, rated for 150 mA with a DC resistance of 1.4 Ohm. The self-resonant frequency of 6 MHz sets the upper bound for the inductor's useful range — above that, the parasitic capacitance dominates and the impedance drops. For a 100 µH part, this is typical of a general-purpose wirewound construction.
