10Base-T Protection
Capacitance across the pair of wires = (D1 || D2) + P0640EA/SA
The MUR 1100E diodes capacitance is approximately (10 pF || 10 pF) 20 pF. Then, adding
the capacitive effect of the SIDACtor (typically 50 pF), the total capacitance across the pair
of wires is approximately 14 pF. This provides a GR 1089 intra-building compliant design.
(Figure 3.43)
Note: MURS160T3 is an SMT equivalent of the MUR 1100E.
