Filtering Elements - Capacitors
Discrete Capacitor 340
In high frequencies
capacitors with terminal
lead to parisistic inductors
Discoïdal capacitor 320
No terminal avoid parisistic
inductance
Coaxial Capacitor 340
No terminal avoid parisistic
inductance too.
Different kind of dielectric:
• Ceramic : small signals (Feed-through or surface mount filters). X7R or NPO (-40/+125°C)
⇒Advantage : small housing.
• Metalized plastic Film(Polyester, Polypropylene) : high signals in voltage AC and DC
(-40/+85°C)
⇒Advantage : High reliability for High current and long life cycle (self healing)

Filtering Elements - Inductors
Properties :
• In current (dissipation, “saturation”, voltage drop….)
• In frequency (Vdc, Vac 50Hz, 400Hz …)
• High weight, housing ….
Different kind:
• Simple winding (without tore)
• Winding around a tore (permalloide, ferrite, C ferrite circuit , steel…)
• Ferrite inductor: for 320 filter
• Substractive flow inductor (High value of inductor in Common mode)

Feed-through filters
1. Low-pass filtering C, L, П and T cell in feedthrough tube
(from Ø30 (3mm) to Ø170 (17mm))
Available AIR 2021E => update EN2382 in 2014
2.12 ESA Specifications (from Ø30 to Ø100):
3008/020, C, Ø30
3008/029, L, Ø100
3008/031, C, Ø35
3008/025, П, Ø35

Surface mount filters
Surface Mount Device (SMD) filter based on the same
construction of tubular filter with shielded package.
1.
Low-pass filtering C, L, П and T cell to mount on PCB
(fromØ30 (3mm) to Ø170 (17mm)).
2.
4 ESA specifications (Ø35):
3.
30% lighter
3008/034 for C cell
3008/036 for L cell
3008/037 for П cell
3008/035 for T cell
Shorter package offered as SCFMCS C cell in diameter 3.5mm
The advantage is a lenght arround 7,5mm instead of 12mm
for already qualified C cell version and for the same
performance.

Multiways filters
3.
Customized filter based on customer request.
1.
Multiways filter implementation, custom packages,
Not ESA
but can be
space qualified
2.
Advantages:
•
•
•
Using EFD Mechanical division to reach customer requirements.
Improvment of installation and housing.
EMC control of the entire implementation.
