ST’s EMI and common-mode filters (ECMF) and ASIPs for automotive applications are AEC-Q101 qualified and compliant with IEC 61000-4-2, ISO 10605, and ISO7637-3 for slow and fast transients.
Why are EMI filters and ECMF required?
Designers need EMI filters to comply with regulatory agency requirements in many markets that impose strict limits on radiated and conducted emissions.
EMI filters help designers ensure system immunity and fast design EMC compliance by mitigating conducted EMI and radiated emission in robust solutions.
They help ensure certification for the following standards:
- CISPR-25, international standard for radio disturbance characteristics
- 2004/104/EC European standard for radiated emission and immunity
- SAE J1113/41 for North American markets
These filters are useful in serializer/deserializer (SerDes) applications, including FPD-link, GMSL, and MIPI DSI or CSI. They help avoid vehicle-to-everything (V2X) frequency radiation (5.9 GHz) and global navigation satellite system (GPS, Glonass, BeiDou, Galileo, and IRNSS) frequencies.
What are the benefits of EMI of ECMF filters for automotive?
ST’s EMI filters, ECMF, and ASIP integrate 15kV ISO 10605 surge protection, combined with filters to offer higher integration. Thanks to its thin-film, high precision process, ST’s EMI and ECMF filters offer high design versatility and resolve many EMI issues.
EMI filters attenuate differential noise and ECMF filters attenuate common-mode noise.
They can reject specific frequency bands and mitigate high-frequency noise, while making end applications smaller and easier to design.
In this video, we explain why it is important to protect against electrostatic discharges. We give a quick demonstration to show exactly what happens when you shoot at a microcontroller with an ESD gun!
