 | | LEGO train wire inductors and DCC —Ted Michon
|
| | | Anyone know the value of the inductors molded into the LEGO track connector wires? Considering the recommendations against (parallel wired) capacitors on the inputs to DCC decoders, then (seried wired) inductors would create a similar problem (...)

There would still be some coupling (and back EMF?) though... Sorry I don't (...) (20 years ago, 26-Jan-05, to lugnet.trains, FTX)

| | | | (...) Hi ! The devices you are referring to are RFI suppressors. They are simply little blocks of ferrite surrounding the wire to add a miniscule (a few hundred nanohenries at most) amount of inductance to the wire so high frequency doesn't get (...)
