Toroidal Chokes for Tube Applications
High quality inductors for tube applications complement PLITRON’s power and output transformers.
Like the other PLITRON tube audio transformers, these units are encapsulated in spun aluminum cases with textured black finish.
Toroidal architecture brings many of the same advantages to inductors as it does for power transformers. Inductors are common in analog and signal processing applications.
When used in conjunction with capacitors, they form an LC filter circuit, to remove DC fluctuations after rectification in power supplies.
Hi-B electrical steels used in toroidal cores are classified as ‘square-loop’ materials, thus they are linear in operation and exhibit high saturation levels. However, the knee of the curve is abrupt and becomes non linear, and above that point can be driven into saturation – especially when used in DC filtering applications.
