Example Data Showing Results using
the FLT007A0 Modules
Figure 9 shows example results obtained using a
QBE025A0B1 DC/DC converter module with the
FLT007A0 filter module. The QBE025A0B1 module is
operated at an input voltage of 43.2V and output
loading corresponding to an input current of 6.2A, a
level close to the 7A capability of the FLT007A0 filter
module. A 10nF ceramic capacitor was connected
between Vin(-) and Vo(-) and a 4700pF ceramic
capacitor between Vin(+) and Vo(+). The results show
that the filter module is capable of meeting EN55022
Class B limits with sufficient margin.
