Additional Notes

MDI model 3723 hermetic power line EMI filters compliment MDI 3700 series DC-DC converters without internal filters, to meet the latest MIL-STD-461C, CE03, CS01 and MIL-461D-G, CE102, CS101 test method requirements.

In applications where low reflected noise currents are needed to meet MIL-STD-461, power line filtering provides attenuation to reduce common mode (line to ground) and differential mode (line to line) currents. MDI’s model 3723 provides such filtration in both modes to provide compliance whether measured in dBuA or dBuV test modes.

The resulting low insertion loss design achieves the necessary attenuation for CE03 or CE102 compliance while minimizing the possibility of excessive input filter impedance mismatch that might otherwise result in DC-DC converter loop instability.

The filters are rated as completely compatible with all normal, abnormal, emergency, over/under voltage and transient conditions listed in MIL_STD-704A-F. A single filter can serve several DC-DC converters up to the rated maximum and two or more 3723 filters may be used in parallel to serve multiple DC-DC converters sharing the same input bus.
