Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of neonatal incubators?

EMC design for neonatal incubators requires attention to the heating and control units. The AC power leads for the heater (e.g., PTC or infrared) should be fitted with ferrite cores to suppress high-frequency noise propagation along the power lines. An RC snubber circuit can be connected in parallel across the solid-state relay (SSR) or silicon controlled rectifier (SCR) controlling the heating power. Sensor signal lines used to monitor temperature and humidity inside the incubator should be shielded, and the signals should be low-pass filtered before entering the control board. The microcontroller (MCU) clock circuit should be shielded; when its I/O ports drive fans or alarms, a small resistor can be connected in series or a buffer driver can be used to mitigate edge noise and reduce radiation.
