[0002] Currently, most suspension system motor pumps directly solder large capacitors and inductors onto the PCB board. This layout has the following problems: First, large capacitors and inductors occupy a lot of PCB board space, limiting the layout of other circuit components on the PCB board and hindering the miniaturization design of the motor pump. Second, the heat generated by large capacitors and inductors during operation is superimposed on other heat-generating components on the PCB board, resulting in poor heat dissipation and affecting component lifespan and system stability. Third, independently installed large capacitors and inductors are prone to loose electrical connections under vibration, and maintenance and replacement require complex operations on the PCB board, increasing maintenance difficulty and cost.
