This is a 5,432 foot spool of served litz wire. The construction of this wire is 8 strands of 38 AWG wire, and it is served with a single layer of white nylon strands. In general, litz wire is made up of individually-insulated strands of magnet wire that are twisted together in a specific pattern. This unique construction mitigates skin and/or proximity effects and lends to fewer losses in high frequency applications.
