| Subject: | LED Noise Filter |
As should have been expected, our ebay sourced PAR36 landing and taxi
lights (4 in total) are producing varying levels of VHF noise. I see lots
of old discussion about this on the list in 2013, but no products or
diagrams for filters. I am planning on ordering the parts from digikey and
making some filters unless there are some inexpensive filters available
that are suitable for 18W LED lamps?
The only circuit diagram I found online was
http://www.ptcaviation.com/wordpress/pi-filter/
Should I go with a simple 1 inductor 1 capacitor filter for each light or
the more complicated version diagrammed above? Does it make any difference
if we are planning on switching the power to 2 of the lights at 1 Hz?
Thank you,
Sebastien

The extra cost of the pi filter is so small I would just use them without e
ven trying a test of the simpler circuit.
One really small correction on the above diagram. C1 and C2 are to filter
high frequency noise while C3 is for lower frequencies. The leads from the
LED to the first high frequency capacitor should be as short as possible.
Therefore, the positions of C2 and C3 on the diagram should be swapped.
