Checking the contents of the LP filter bag, product number 1021.
Check that the bag contains three toroidal cores, they can be black, red, yellow or other colors depending
what frequency they are made for. Typically, they are yellow.
The larger bag also contains two smaller bags that holds surface mount capacitors. To avoid getting the
capacitors mixed up I recommend that they stay in their bags until it is time to solder them to the board.
Finally, there is also a piece of wire that will be used for the toridal cores.
Checking out the schematics for the filter.
If we check the schema, we see that the inductors are called L1 to L3 and that the capacitors are designated C1
to C4
