15. INPUT FILTERING AND EMI INTERFERENCE
The VHB75W converters have input capacitors that control input current ripple and the associated EMI interference. However, it
has not been tested to a formal standard for conducted emissions. Additional filtering may be needed to ensure compliance to an
EMI standard. Refer to FIGURE 10 for a reference circuit.
V-Infinity offers a line of dc input filter modules designed to help reduce common and differential mode noise. The table below
provides a list of dc-dc converter models within the series and the mating dc input filter.
note: The recommended components are a starting point but not guaranteed for meeting these EMI requirements. More or less
