1-Subject
The EMI front filter kit KG9501 enables Gaia Converter DC/DC modules or preregulators front-end
modules below 50W power to be fully compliant with the MIL-STD-461-C Part 2 & 3 standard as
follow :
• CE03, class A1, narrowband
• CE03, class A1, broadband, curve# 1 & 2
• CS01, class A1, consult factory for criteria
• CS02, class A1
4
• CS06, class A1, spike # 2
This EMI front filter kit is compatible with all GAIA Converter DC/DC modules with J family of input
range (16-40 Vdc) or H family of input range (9-36 Vdc), with all pre-regulator PGDS-50 series and
can drive up to 2A input current.
This EMI front filter KG9501 is a kit of 15 components as follow.
