Quality You Can Rely On

We combine automated testing with expert inspection to ensure component quality and consistency from the first prototype to production.
We are ISO 9001:2015 certified, and the first Italian manufacturer of PCB transformers to achieve a ISO 9000 certification, back in 1992.
We also contribute to international standards as an active member of Technical Committee 96 (EN 61558).

Full Regulatory Support

We help you meet safety and EMC standards early on—avoiding delays, redesigns, and unexpected costs.

Innovation Through Collaboration

Itacoil works with leading semiconductor manufacturers to co-develop demo boards and push the boundaries of power electronics innovation.

Committed to Sustainability

Thanks to the expansion of our photovoltaic system, Itacoil’s headquarter has transitioned from energy consumer to net producer of renewable energy. We believe in innovation that respects the environment—today and for the future.
