Pros & Cons of Using Low-Profile Planar Transformers & Inductors

Electronetics deploys this relatively new construction technique to design custom planar transformers and inductors with extremely low profiles. These components are ideal for applications with space or height restrictions, such as mobile electronics.

We build stand-alone magnetics and can also consult on designs to seamlessly integrate the core and coils into your printed circuit board. Pros and cons of planar magnetics are as follows:

Pros

• Very low profile
• Excellent repeatability from unit to unit
• Simple construction increases volume producibility
• Especially suitable for higher operating frequencies

Cons

• Higher cost of materials
• Not suitable in complex coil configurations
• Limited turns ratio options
• Limited core types and sizes limit design flexibility
