Innovative low pass filters

Exxelia has developed several ranges of miniature filters with different low-pass configuration (C, L, Pi, T, 2xPi, 2xL and 2xT) mainly intended to protect electronic equipment from interferences.


Low-pass filter solutions are mainly used for EMI suppression in electronics systems. Exxelia Technologies (ex-Eurofarad), part of Exxelia Group, has developed several ranges of miniature filters with different low-pass configuration (C, L, Pi, T, 2xPi, 2xL and 2xT) mainly intended to protect electronic equipment from interferences.
Exxelia Technologies produces sophisticated filters assembling Exxelia Group’s manufactured ceramic capacitors (X7R/ NPO) with ferrite inductors or winding cores in a shielding case. This solution’s main benefits are performance, reliability and optimal traceability.

Considering a filter in a shielding case implies a good metallic package to insure high shielding performances with attenuation up to 10 GHz. Among options, Exxelia offers glass sealing, steel or kovar package using tin, silver or gold plating treatments to withstand any thermally or mechanically challenged applicaiton.
Exxelia offers innovative EMI suppression filter solutions providing great shielding performance including the FC030 feedthrough mounted on shielding enclosure and FCM030 series designed to prevent EMI on printed circuit board.

FC030 series is feedthrough filter allowing to prevent not only EMI conduction but also EMI radiation on power supply or data signals designs up to 200V. FC030 insertion loss can be 20dB at 1MHz to reach 70dB up to 10 GHz. FC030 series is extremely performant on low frequencies applications.
On the other hand, FC030 can offer very low capacitance values starting from 5pF allowing to protect high bandwidth data signals. Operating temperature from -55C° up to +175C°. FC030 series is ESA qualified.

FCM030 features same design and performances’ as FC030 and is intended for surface mount devices. FCM030 is packaged in full metallic silver plated allowing optimal contact with ground plane that improves the interferences flow to the ground.
The series particularly fit for amplifiers, radars, sensitive HMI, accurate measuring.

Our presence at Electronica 2022

Aircraft & Space Embedded Products cluster, bringing together components that can be mounted on a satellite, radar or aircraft, we were ready to introduce two innovations that are particularly well suited to the challenges of the aviation of the future and the objectives of decarbonisation of the air. Its latest film capacitor innovation called MML™ (named after its "Miniature Micro-Layer" dielectric) shows an energy density up to 4 times higher than other film dielectrics. MML® technology makes power capacitors smaller, lighter and compatible with higher temperatures, and is therefore particularly suitable for DC-Link, decoupling & charge-discharge applications. Alongside MML™ components, we presented the latest innovations in magnetic components, saving up to 40% in weight and 20% in volume while dissipating more power, some of which have been designed for eVTOL applications, as well as the CCM & Dual Active Bridge multi-output transformers. Rail & Energy Exxelia showed Alcon capacitors for the first time at its Rail & Energy cluster. Alcon is one of India's leading designers and manufacturers of standard and customised aluminium electrolytic and film capacitors for niche markets. Alcon supplies many of the components used in trains, electrical charging stations and power generation systems. Exxelia's film and ceramic capacitors for signalling systems, as well as current and instrument transformers, and resistors was presented on display.   Medical​​ Exxelia Micropen & Exxelia Ohmcraft components was showcased at Electronica for the very first time with a unique offering for the medical sector. Indeed, Exxelia Micropen's unique additive printing technology is widely used for disposable medical equipment such as endotracheal tubes or surgical ablation tools, and high voltage resistors are used in laboratory equipment such as mass spectrometers or thermal cyclers.  

Magnetic Components based on Adaptive CCM Technology at APEC – Booth# 653 –

Exxelia will exhibit the CCM series during the Applied Power Electronics Conference at Exxelia’s booth #623 from March 27-30, 2017 in Tampa, FL. Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC.  Component materials meet UL 94-V0 rating. Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
