In applications where adverse electromagnetic fields exist, an

additional EMI protection may be necessary. In Figure 3, there is an

example of an electromagnetic interference protection of the PMB100

module. The EMI filters should be placed as close to the pins as

possible.

Figure 3 Electromagnetic interference protection of the

PMB100. Filters, for example, T-type EMI

suppression filters with capacitance of 47pF (like

Murata, DSS310-55Y5S470M100). This connection

setup fulfills the RF field immunity standard

EN61000-4-3.
