17. INPUT FILTERING AND EMI INTERFERENCE
The VHK50W 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 10.1 and 10.2 for reference circuits.
note: The recommended components are a starting point but not guaranteed for meeting these EMI requirements. More or less
filtering may be required for a specific application or to meet other EMI standards, e.g.MIL-STD-461
