Abstract
A multi-tapped surface mount inductor (300) providing high quality factor (Q) and high inductance is capable of being surface mounted on any of its four sides. An inner substrate layer(s) (322) is provided with metallized patterns (328, 332) and vias (336) to form a multi-turn coil. The inner substrate layer (322) is then sandwiched between first and second outer substrate layers (324, 326) to form a six sided structure. Tapped element(s) (304) can be tapped off the multi-turn coil in increments of a quarter turn or less to provide a multi-tapped surface mount inductor capable of being mounted an any of its' four side surfaces (310, 312, 314, 316). When tapped element(s) (204) are tapped symmetrically between the input/output ends (214, 216), the surface mount inductor (200) may interchange its' input/output ends (214, 216) making the component surface mountable in eight different positions.
