Which EMC (electromagnetic compatibility) components are helpful for the design and modification of air wave pressure therapy devices?

The EMC design of this device requires handling multiple inductive loads. The power supply line for the air pump motor (typically AC or DC brushed) has a ferrite core in series, and a small capacitor is connected in parallel across the motor terminals. A freewheeling diode must be connected in parallel across each solenoid valve coil. The pressure sensor signal lines use shielded wires and are filtered by an RC low-pass filter after entering the control board. The microcontroller (MCU) I/O ports must have sufficient drive capability, or the valves and pumps can be controlled using driver chips such as Darlington arrays/ULN2003, which typically integrate freewheeling diodes. A medical-grade power adapter is used, and the internal PCB layout separates the power and logic sections.
