At Mech-Tronics, we design and manufacture transformers and inductors in various shapes and materials depending on the specifications and requirements of your application. As you search for the right component for your project, you need to consider:
- Whether you need a transformer or inductor
- Your operating frequency requirements
- Your voltage/current requirements
- How much size and space you have available
- Your mounting requirements
- EMI (Electromagnetic interference)
- How much heat dissipation or retention you need
If you need guidance in selecting the right component for your application, we can help. Just schedule a free transformer problem solving session and we’ll help you sort through your various needs and requirements.
