Figure 2: Typical Output Impedance (magnitude) of the filter looking

back into its output pins with the input pins connected to a source

with zero source impedance.

Figure 1: Simulation of calculated common-mode and differential-mode current

attenuation. The curves plot the ratio of noise current in a 50Ω LISN sensing port

connected to the noise output side of the filter to the noise current on the input side.

The filter case is also connected to chassis ground. Refer to Figures A and B.

Figure 3: MIL-STD-461E Method CE101 Low Frequency Conducted

Emissions of the MQHE-28-P filter with a MQHL-28-05S at 50W

output. Limit line (in red) is the ‘Submarine Applications DC Curve’.

Figure 4: MIL-STD-461E Method CE102 High Frequency

Conducted Emissions of the MQHE-28-P filter with a MQHL-28-05S

at 50W output. Limit line (in red) is the ‘Basic Curve’.

Figure 5: MIL-STD-461E Method RE101 Low Frequency Radiated

Emissions of the MQHE-28-P filter with a MQHL-28-05S at 50W

output. Limit line (in red) is the ‘Standard Curve’ from MIL-STD-

461C Method RE01, which is more strict than all RE101 limits.

Figure 6: MIL-STD-461E Method RE102 High Frequency Radiated

Emissions of the MQHE-28-P filter with a MQHL-28-05S at 50W

output. Limit line (in red) is the ‘Submarine External to Pressure

Hull Curve’.
