Additional Notes


MDI Model 53747 hermetic power line EMI filters compliment MDI DC-DC converters without internal filters to meet the latest MIL-STD-461C, CE03, CS01 and MIL-STD 461D-G CE102 and 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 53747 provides such filtration in both modes to provide compliance whether measured in dBuA or dBuV test modes.

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 converts up to the rated maximums.
