Electro Magnetic Compatibility (values depend on R_M!)
Characterization of Electro Magnetic Compatibility are carried out on sample base of one
qualification lot. Not all specification parameters have been monitored during EMC
exposure. Only key parameters as e.g. switching current have been monitored

1) According to 7637-1 the supply switched "OFF" for t = 200 ms.
2) According to 7637-1 for test pulse 4 the test voltage shall be 12 V ± 0.2 V. Measured with R_M =75Ω only.
Mainly the current consumption will decrease. Status C with test circuit 1.
3) Applying in the board net a suppressor diode with sufficient energy absorption capability.
