I have two options for input filter having ferrite bead and reverse polarity protection diode as shown below
The input supply is from 9 - 16 VDC. This is meant to protect the solution from EM immunity requirements as per ISO 7637.
I am also unsure about the values of the capacitor to be used in option 2.
The input current is around 1.5A.
Which of the above two options fits the best?
Also, how should I place these components on the PCB.
