Exxelia is certified EN 9100, a quality standard specific to the aerospace, space, and defense sectors. Our facilities are also ISO 9001 certified (quality management), and some are certified ISO 13485 for medical devices. Other industry-specific standards, such as NADCAP or AQAP, may also apply depending on the products and markets.

The EN 9100 standard ensures a rigorous quality management system tailored to the critical requirements of the aerospace, space, and defense industries. It is required by major OEMs such as Airbus, Safran, Thales, or CNES. This certification guarantees product traceability, risk management, and compliance with international standards.

Yes, some of our facilities are ISO 13485 certified, the quality standard for medical devices. This certification enables Exxelia to design and manufacture components (such as coils, sensors, or capacitors) used in high-reliability medical equipment, including MRI scanners, ventilators, and imaging systems.

The railway industry demands durability, reliability, and long service life. While a dedicated certification like EN 9100 is not required, Exxelia applies IRIS standards and complies with IEC/EN regulations specific to railway applications. Our quality processes ensure component compliance for trains, metros, and tramways, including fire safety and electromagnetic compatibility.

Yes. Exxelia meets defense industry requirements through its EN 9100 certification and compliance with military standards (MIL-STD, STANAG). Our components are qualified for critical applications such as RF systems, embedded electronics, guided munitions, or radar systems. Some products are also subject to customer-specific qualification procedures.

The "Thermal Optimization" initiative aims to design the smallest possible high-reliability components for a specified power rating by incorporating the correct design margin. The main benefits include a better understanding and control of the operating temperature of our magnetic components, leading to size and weight reductions of up to 30%, and optimized thermal dissipation.

This initiative focuses on designing a control system that mitigates partial discharge inception. The goal is to create the smallest, highly reliable component for specified high operating voltages. The key benefit is achieving long-term reliability at high voltage with no partial discharge.
