ESD/EFT Protection Component Selection
We are designing a custom board. We need to meet IEC/EN 61000-4-3 (RF Immunity).
Can anyone share special criteria required for component selection and suggestions to consider while designing?
There are many resources on TI's web that can assist you.One of these is TI Training.
This will show training topics related to the IEC specification.
EMI immunity is platform specific, components, layout.You may find information in device product folders.|Here is an example.
TLE2141 and TLE2141-Q1 EMI Immunity Performancehttp://www.ti.com/lit/an/sboz026b/sboz026b.pdf
"EMI Rejection Ratio (EMIRR)
The electromagnetic interference (EMI) rejection ratio, or EMIRR, describes the EMI immunity ofoperational amplifiers (op amps). An adverse effect that is common to many op amps is a change in theoffset voltage as a result of RF signal rectification. An op amp that is more efficient at rejecting this changein offset as a result of EMI has a higher EMIRR and is quantified by a decibel value."
So there are many ways to find information in the TI web.If you have device specific questions, create a thread and ENTER A PART NUMBER, in order for the thread to be routed properly.
