Additional Notes
MDI model 53738 and 23739 hermetic power line EMI filters allow DC-DC converters without internal filters to meet the latest MIL-STD-461C, CE03 and CS01 and MIL-STD D-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 53738 & 23739 provide such filtration in both modes to provide compliance whether measured in dBuA or dBuV test modes.
The resulting lower insertions loss design achieves the necessary attenuation for CE03 or CE102 compliance while minimizing the possibility of excessive input filter impedance mismatch mat might otherwise result in DC-DC converter loop instability.
The filter are rated as completely compatible with all normal, abnormal, emergency, over/under voltage and transient conditions listed in MDL-STD704A-F. A single filter can serve several DC-DC converters up to the rated maximums and two or more filters may be used in parallel to serve multiple DC-DC converters sharing the same input bus.
