In the past, RFI shielding has mainly addressed frequencies of up to 10GHz, but the requirement for RFI/EMI shielding is continuing to grow, with many more electronic devices entering the market. However, the requirement is also changing, as the frequencies used are getting higher and ultra-reliable, low-latency communications between devices are needed in safety-critical applications. These require real-time access to rapidly changing data, such as Advanced Driver Assistance Systems (ADAS) which are becoming common in new vehicles.
Electric vehicles are providing a new market for EMC products, with shielding required for battery management systems, DC-DC converters, LED lighting, and sensors. The charging infrastructure is also important, as the success of electric vehicles will rely on charging your vehicle quickly. The fast chargers found on motorways and service stations require shielding for the DC-DC converters. Lower-power charging points, like those you have at home, only need to meet the minimum EMC requirement to the same level as street lighting.
