An electronic device may include surface mount technology components mounted to a printed circuit board. The surface mount technology components may include electrical components such as resistors, inductors, and capacitors. In order to reduce the size of the electronic device, surface mount technology components may be stacked. A surface mount technology component may be mounted to metal members that electrically connect the surface mount technology component to contact pads on a printed circuit board. A surface mount technology component may be provided with integral standoff portions, and a second surface mount technology component may be mounted to the integral standoff portions. A single surface mount technology component may be used to implement different circuits depending on which face of the surface mount technology component is mounted to the printed circuit board.
