Additional Notes

MDI Model 3742 hermetic power line EMI filters compliment MDI DC-DC 3700 series converters without internal filters to meet the latest MIL-STD-461C, CE03, CS01 and MIL-STD 461D-G CE102 and CS101 and SSP30237 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 3742 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 SSP30237. A single filter can serve several DC-DC converts up to the rated maximums and two or more 3742 filters may be used in parallel to serve multiple DC-DC converters sharing the same input bus.
