Electromagnetic Compatibility

Electromagnetic Compatibility (values depends on RM!). See Figure 9

Note:

Characterization of Electro Magnetic Compatibility is carried out on samples based on one

qualification lot. Not all specification parameters have been monitored during EMC exposure. Only

key parameters e.g. switching current have been monitored.
