Transformers integrated with a choke


Transformers integrated with a choke are a compact combination of transformer and inductive element. Transformer part of this combination adjust the voltage value to the receiver requirement while the choke part effectively suppresses the disturbances. Transformer integrated with a choke is a component with high short circuit voltage.
