With the development of automotive intelligence, today's cars, more and more electronic equipment in them, so that the owner enjoys more driving fun at the same time, but also provides a high degree of reliability and safety. However, the safety of these electronic devices and the normal operation of the car is closely related, and even related to the personal safety of the owner and passengers. If the circuit protection measures are not in place, it is easy to cause electronic equipment to strike or even permanently damage, such as the most common load-throwing phenomenon.
In accordance with relevant international and domestic standards and regulations, for the sake of automotive safety and longevity, electronic equipment in places such as ignition modules, electronic regulators, airbags, display instruments, car navigation, and reversing systems need to be tested for load-throwing voltage shocks by ISO7637-2 5a/5b. ISO7637-2 5a/5b load-throwing tests have become a mandatory step in the process of automotive electronics. The ISO7637-2 5a/5b load throw test has become a must for automotive electronics.
Not to know ISO7637-2 5a/5b test
ISO7637-2 standard: Road vehicles - electrical nuisance caused by conduction and coupling, electrical transient conduction along the power line, there are five test pulse waveforms, respectively, are waveforms 1, 2a/5b, 2a/5b, 2a/5b and 2a/5b. Are waveforms 1, 2a/2b, 3a/3b, 4, 5a/5b. In all test pulse waveforms, the simulated load-throwing 5a/5b waveform is the most energetic pulse. Simulated load-throwing test, in addition to testing the automotive electronic equipment in the waveform 5a/5b under the action of anti-interference ability, but also test the load-throwing on the equipment components of the destructive.
It is undeniable that the ISO7637-2 5a/5b test is the most destructive test, and also the most difficult test for automotive electronic equipment to pass. Generally speaking, if you pass the ISO7637-2 5a/5b test, the other waveform test tests will be out of the question. In reality, it is the 7637-2 5a/5b simulated load-throwing impact test that really puts automakers in a difficult position. DOWO has a professional EMC lab, provides free 7637 testing, and offers high-quality circuit protection devices to help pass the 7637-2 5a/5b simulated load-throwing impact test.
