The LQH43CN100K03L is a wirewound SMD Chip Inductor/Coil with 1812 case. The wirewound inductor consists of a copper wire spirally wound around the ferrite core. The wirewound inductor for power circuits, coated with various resins over the copper wirewound around the ferrite core. The purpose of the coating resin is to improve the strength of the product. The merits of using a wirewound product are demonstrated when used in large current areas and high inductance areas.
