Power Inductors

An Inductor is nothing else but a wound coil, which smoothes the current flow or stores the electrical energy.

Functions : 

• Circuit protections against high current peaks (Surge Coil) 
• Smoothing the current flow : Filtering and noise cancellation 
• Energy transfer in converters 
• Impedance adaptation in LLC 

Type of inductors from our range :

• Filtering Chokes (Mainly Power) 
• Differential Mode Choke   
• Power Factor Correction (PFC)
• Interphase Inductor for “400Hz” Power Supply
• Common Mode Choke (CMC) for EMC
   

Yes, Exxelia's magnetic components are designed and manufactured to meet or exceed industry standards and certifications, including RoHS, REACH, and MIL-STD.

Encoders can use either optical or magnetic sensing technology. 

Optical sensing provides high resolutions, high operating speeds, and reliability, long life operation in most environments. 

Magnetic sensing, often used in rugged applications provides good resolution, high operating speeds, and maximum resistance to dust, moisture, and thermal and mechanical shock. 

Optical Encoders: principles 

Optical encoders’ principle of operation is relatively simple; a light source (photo-emitter) sends light through a mobile disk or scale, consisting of a succession of opaque and transparent parts, on photo-receivers. When the disk or the scale moves, it conveys or alternatively blocks the light emitted by the source; the scale or the disk is acts in fact as a beam switch. The photoreceiver generates an electrical signal, which is processed and analyzed in order to allow encoding the system position. 

An optical encoder consists of three major subsets: 

• Encoder housing. 
• Optical block: consisting of an emission system, an optical coding system and a detection system. It generates the position function signal. 
• Electronics block: it allows amplifying, converting and processing the signal. 

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.

Exxelia SVM designs inductors and chokes to block high-frequency ripple currents. Examples include filter inductors (5 mH, 15 A rms at 40 kHz; 10 mH, 10 A; dimensions specified). They also provide LCL filter inductors using rectangular Litz wire rated for high current (e.g., 100 µH, 360 A continuous, 510 A peak, 50 Hz–3.5 kHz).

Exxelia SVM develops fully custom magnetics, offering in-house tooling, MATLAB/FEMM modelling, special core designs, Litz wire constructions up to 350 A, and complete solutions from prototype to packaging.
