Hi,
I'm looking at the internals of a car aerial in-line filter (noise
suppression). It has a coax input& output & another white lead... Should the
extra lead go to ground, earth or where?
It's a passive filter with a 10nF ceramic cap between input & output, and
what looks like a 5.6uH & 2.6mH & 22uF 50V cap in series between input &
ground. At the junction of the 22uF cap & 2.6mH inductor, there is a tap to
a 2.2uH inductor, the other end of which is connected to the white lead. I
hope this makes sense.
I'm pretty sure of the component values - I checked then with an Atlas LCR
meter (good enough for this job).
What's this extra white lead for?
Thanks
