Note:
Electromagnetic emission classification (EME)
Electromagnetic emission classes presented below are typical data found on bench test. For
detailed test description please refer to ’Electromagnetic Emission (EME) Measurement of
Integrated Circuits, DC to 1GHz’ of VDE/ZVEI work group 767.13 and VDE/ZVEI work group
767.14 or IEC project number 47A 1967Ed. This data is targeted to board designers to allow
an estimation of emission filtering effort required in application.
