Additional Details

The 0805 package size refers to the physical dimensions of the inductor, with a length of 2.0 mm and a width of 1.2 mm. The high self-resonant frequency (SRF) indicates the frequency at which the inductor's impedance becomes primarily resistive. The Q factor (quality factor) is a measure of the inductor's efficiency, with higher values indicating lower energy loss. Wire-wound inductors typically offer higher Q factors compared to other inductor technologies. These inductors are typically mounted using solder reflow techniques in automated assembly processes.
