Series Description
The GAIA Converter filter module FGDS-20A-50V provides a state-of-the-art product to fulfill Electromagnetic Interferences (EMI) requirements for Aerospace and Defence applications. The FGDS-20A-50V is a very compact and low loss solution for applications requiring up to 20A input current. 
The FGDS-20A-50V complies with major standards including : 
- the US MIL-STD-461 rev D, E and rev F, 
- the international DO-160 rev C, D, E, F & rev G.
In particular, the filter module is compliant with the following requirements of MIL-STD-461D/E and DO-160-C/D/E standards :
- MIL-STD-461D/E/F Part 2. & 3. requirements :
. Conducted Emission (CE) 
. CE102, 
power leads, 
emission over 10KHz to 10MHz, 
basic curve. 
. Conducted Susceptibility (CS) 
> CS101, 
power leads, 
frequency 30 Hz to 150 KHz, curve #1, 
> CS114, 
bulk cable injection, 
frequency 10 KHz to 400 MHz, 
> CS115, 
bulk cable injection calibrated spike, 
> CS116, 
damped sinusoidal transient.

DO-160-C/D/E/F/G requirements :
. Conducted Emission (CE) 
> Section 21 
power lines, 
emission over 15 KHz to 152 MHz, 
category B, AZ &LMH.
. Conducted Susceptibility (CS) 
> Section 20 
power lines, 
frequency 10 KHz to 400 MHz. 
In addition, this filter withstands in a transparent state without dammage the transient and spike requirements of : 
- MIL-STD-704A/D/E/F with up to 80V/100ms, 
- MIL-STD-1275A/B/C/D with up to 100V/50ms. 
The FGDS-20A-50V is suitable for all GAIA Converter DC/DC converters and DC architecture from 50W up to 300W output power, up to 20A output current, up to 50V permanent input voltage.
