An improved structure of a multi-slotted iron rod includes a core, a coil, and a lead frame. The core is a rod is made from good magnetic iron powder. The core has a fixture area and a winding area. The winding area has several winding sections and isolation sections. The winding area is used for coil winding. The isolation sections serve as capacitors. The fixture area has a hexagonal cross section and is used as a fixing end during winding. The coil winds on the winding sections of the core. The lead frame is attached to the two sides of the isolation sections of the core for connection to an electrical circuit. The device utilizes the above components to wind the coil on the winding sections of the core. The output pin of the coil is soldered to the lead frame of the isolation sections. The lead frame is soldered on the PC board. The capacitor of the isolation section of the core is connected in parallel to the coil in the winding section. The lead frame is soldered directly to the PC board or is mounted by Surface Mounting Technology (SMT) to the PC board. The device functions as capacitor and inductor at the same time.
