Potted Transformers

Transformers can be potted into circular shells or potting boxes to give additional protection in adverse enviromental conditions and to provide an attractive uniform package.

Plastic enclosures may be used and a range of metal shells are also available which can result in improved electromagnetic and electrostatic screening.

An extensive range of rectangular boxes is available, enabling laminated transformers to be potted and also facilitating the potting or encapsulation of the smaller ferrite components for PCB mounting
