Common mode noise capacitance c
(See note below)
Notes  : it is suggested to use a common mode capacitor Cc (10 nF/1.500V) to increase EMI performance. This capacitor should be layed-out as close as possible from the
DC/DC converter.
* For connection to chassis ground, if a higher isolation is required, it is suggested to use 10nF with voltage rating compliant with application requirements as capacitors
C5 and C6.
3- Schematic
The EMI front filter kit KG9501 can be used either :
 directly in front of any GAIA Converter DC/DC modules or assembly of DC/DC modules up to 50W power
 in front of GAIA Converter pre-regulator PGDS-50 series.
Both schematics are resumed hereafter.
3-1 Connection to GAIA Converter DC/DC Converter
3-2 Connection to GAIA Converter Pre-regulator PGDS-50 & DC/DC Converters
Notes  :  it is suggested to use a common mode capacitor Cc (10 nF/1.500V) for each DC/DC converter to increase EMI performance. This capacitor should be layed-out
as close as possible from the DC/DC converter.
* For connection to chassis ground, if a higher isolation is required, it is suggested to use 10nF with voltage rating compliant with application requirements as capacitors
C5 and C6.
