For my power supply in automotive project, I understand that I should have a series input resistor to help protect against high current. But, I am not sure how to figure out the value and wattage (have read anywhere from 3ohm to 10ohm). Also have read that it should not be SMD type but axial (and high wattage, with no tracks below, not sure why). Can someone explain please? Thanks.
