100% invar tuning screws with self-locking system 
Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

High power and high frequency ceramics with the new C48X dielectric

Range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10–4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability.

Magnetic components based on adaptive CCM technology

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 CCM technology adapts to most every need, even the harshest environments, including VIGON® resistance. 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. 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. 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.

Ultra low ESR, high RF power and high self-resonant frequency The new NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment.     Felsic HV, long lifetime and high voltage screw terminal The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For example products can withstand 8 000 hours at 105°C under high values of current which makes them the perfect choice to overcome railway constraints. The family also has one of the lowest ESR for aluminum capacitors, less than 10m0hms in most cases. Products are available for voltages from 160 to 450 Vdc, and offer capacitance values from 1500μF up to 47 000μF. Thus the family is a good compromise between reliability and compacity, with for example 47 000μF @ 160V in a 90x200mm volume.     Cost-effective common-mode chokes qualified for aerospace Designed and qualified for aerospace, the TCM series is available in a through-hole package for horizontal and vertical mounting. TCM common-mode chokes are offered with inductances from 0.7 to 47mH under rated currents from 0.3A to 4A, and thoroughly tested by a dielectric withstanding strength at 1500VAC. Their excellent thermal properties allow the TCMs to operate without a hitch from -55°C up to +125°C, which, combined to the high mechanical resistance of the chosen materials (all meeting to UL94 V0 rating) make those products the perfect fit for aviation, defense and transportation industries.       Two new ranges of Metallized Polyester Film Capacitors qualified for space Ranges PM907S and PM948S of Film capacitors obtained the QPL certification from the European Space Components Coordination (ESCC). PM907S and PM948S part of the PM series, are full ranges of Metallized Polyester Film Capacitors. PM907S products are suitable for voltages from 50V up to 1250V and offer capacitance values from 82nF up to 180μF. PM948S can be used with a voltages from 50V up to 630V with capacitance values from 22nF up to 47μF. Both ranges can support extreme conditions with temperatures from -55°C to +125°C, and offer high energy density, low ESR & ESL and high RMS current. Products are typically being used in SMPS (Switch Mode Poser Suppliers) and BUS filtering.   A new range of high capacitance wet tantalum capacitors The new wet tantalum WT83 capacitors series is based on the CLR93 MIL specification but with double the capacitance. For instance, WT83 offers 1000µf 100V in a D size case. That is a pass for impactful miniaturization of existing designs by playing on both size, by reducing the PCB footprint, and weight. Besides, thanks to their hermetically sealed package, the WT83 series can withstand high vibrations and shock levels (50g and 100g respectively) which makes them the solution of choice for Aviation, Space and Defense.
