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 ________________________________ Message 5 _____________________________________ Time: 10:18:30 AM PST US From: "The Kuffels" Subject: Re: AeroElectric-List: LED Noise Filter Sebastien, << 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 t he more complicated version diagrammed above >> 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.
