The B82479A1223M000 is a 22µH 3.5A fixed inductor manufactured by TDK with a tolerance of 20%. It measures 18.54 x 15.24mm and has a surface-mount design (SMD). It features a ferrite core, with a shielded, grounded construction that helps reduce EMI and improve current capacity. The inductors incorporate a double-sided winding, which helps reduce the current path and reduces DCR for improved performance. It has an operating temperature range between -40°C and +125°C and can be used for a wide range of applications, including power supplies, switching regulators, DC-DC converters, and more.
