Crane Aerospace & Electronics Power Solutions FMCE-0828 EMI Input Filters 28 Volt input – 8 Amp Features Attenuation to 60 dB at 500 kHz, typical • Operating temperature -55° to +125°C • Nominal 28 V input, -0.5 to 50 V operation • Transient rating -0.5 to 80 V for 1 second • Up to 8 A throughput current over the full input voltage range of -0.5 to 50 V • Compliant to -- MIL-STD-461C CE03 -- MIL-STD-461D, E and F CE102 -- MIL-STD-461C CS01 -- MIL-STD-461D, E and F CS101 Input Voltage and Current • Compatible with MIL-STD-704 A-E 28 VDC power bus Input (V) 28 Description Current (A) 8 The FMCE-0828™ EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint’s high frequency DC/DC converters. FMCE-0828 filters minimize electromagnetic interference (EMI) for the MFL, MOR, MTR, MHV and MHF+ Series of converters. These filters are intended for use in 28 volt applications which must meet MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of conducted emissions. One filter can be used with multiple converters up to the rated output current of the filter. 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. Input Ripple and EMI The FMCE-0828 Series filters are rated for full power operation from -55°C to +125°C case temperature. Current is derated linearly to 80% at +135°C case temperature. 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. Common 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 CE03 of MIL-STD-461C and/or CE102 of ML-STD-461D, E and F, a power line filter is needed. The FMCE-0828 EMI power line filters reduce the common mode and differential noise generated by the converters. FMCE-0828 filters reduce input ripple current by 60 dB, typical, at 500 kHz and 1 MHz when used in conjunction with Interpoint’s DC/DC converters.
