The DO3316P-473MLD is a surface mount unshielded Power Inductor with ferrite core. This inductor features gold over nickel over phosphor bronze terminations and is resistance to soldering heat maximum three 40 seconds reflows at +260°C, parts cooled to room temperature between cycles. This inductor also features moisture sensitivity level (MSL) of 1, failures in time (FIT)/mean time between failures (MTBF) is 38 per billion hours/26,315,789 hours, calculated per Telcordia SR-332 and only pure water or alcohol recommended for wash. Current at 25°C causes an inductance drop of 10% typical from its value without current. ±20% inductance tolerance and this high inductance value inductor are perfect for EL driver.
