Matching low-frequency transformers are suitable for operation in boreal climate conditions at ambient temperature from - 60… to +85 oC, including coil overheating and relative humidity up to 93% at +25 oC.

TOT-type transformers are used in household and industrial audio frequency amplifiers.

Transformers are manufactured as assembly components for PCB of semiconductor-based devices.
