Designing for EMC in Vehicle Electronics

摘要

The automobile is a particularly vicious environment for modern electronic components. Ambient temperatures range from -40℃ to 125℃, vibration and shock are constant, and electrical noise can come from a surprising array of sources, such as the windshield wiper motor, fuel pump, spark ignition coils, air-conditioning actuators, intermittent disconnection in the wiring harness to the alternator, and wireless products such as cell phones and pagers.
