1 FME0- EMI Input Filters Features Attenuation to 0 db at 00 khz Operating temperature - to + C Nominal 0 V input, 0 to 00 V operation Transient rating to 00 V for 0 ms Up to. A throughput current Compliant to -- MIL-STD-C, CE0 Description The FME0 Series EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint s high frequency DC/DC converters. FME0 filters minimize electromagnetic interference (EMI) for the MHP0 Series of converters. These filters are intended for use in 0 volt applications which must meet MIL-STD-C CE0 levels of conducted emissions. One filter can be used with multiple converters up to the rated output current of the filter. Input Ripple and EMI Switching DC/DC converters naturally generate two noise components on the power input line: differential noise and common mode noise. Input ripple current refers to both of these components. Differential noise occurs between the positive input and input common. Most Interpoint converters have an input filter that reduces differential noise which is sufficient for many applications. mode noise occurs across stray capacitances between the converter s power train components and the baseplate (bottom of the package) of the converter. Where low noise currents are required to meet MIL-STD-C, a power line filter is needed. The FME0 EMI power line filters reduces the common mode and differential noise generated by the converters. FME0 filters reduce input ripple current by as much as 0 db at 00 khz and db at MHz when used in conjunction with Interpoint s DC/DC converters. Place the filter as close as possible to the converter for optimum performance. The baseplates of the filter and the converter should be connected with the shortest and widest possible conductors. Transients A transient of -00 to +00 V for up to 0 ms will not damage the filter but will be passed on to the converter: Operation over Temperature The FME0- Series filters are rated for full power operation from - C to + C case temperature. Current is derated linearly to zero at + C case temperature. Insertion Loss The maximum dc insertion loss at full load and nominal input voltage represents a power loss of less than %. Packaging FME0- filters are sealed in metal hermetic side-leaded packages. See cases U, V, W, Y, and Z.
