The smaller constructions of Litz Wire Types 1 and 2 are typically used in High Q circuitry, such as toroidal coils and transformers. The larger Type 2 and Type 3 Litz wire designs have greater current carrying capacities necessary for high frequency power supply, inverter and grounding applications. Types 4, 5 and 6 Litz wire constructions all utilize at least one inert core and are used primarily in tuning circuitry for high power radio transmitters. Type 9 coax-style Litz constructions are used to carry high frequency electrical signals with low losses and are engineered to block signal interference.
