Exxelia at EMV
Exxelia is pleased to exhibit at EMV 2019 in Stuttgart, Germany from March 19 to 21 inHall C2 Booth# 113, Exxelia will be introducing a new filter design conception.
Showcased at Exxelia’s booth #113 in Hall C2, will be Asymmetric filter solutions, the most optimized design in the market.
Smaller, lighter and consequently easier to install, Exxelia is the only manufacturer to solve HEMP requirements with Asymmetric filter designs, hence addressing the security challenges of tomorrow.
Exxelia pushes the limits of design with the new BDP series allowing a 50% space saving in your installation while keeping high technical specifications (insertion loss of 80dB, 1250A, 300kHz to 18GHz) and complying with the MIL STD 188 125 1&2 test requirements.
Asymmetric designs allow to combine safety and miniaturization while still handling HEMP and TEMPEST requirements. Three important benefits stand out from this conception, starting with a lower heat dissipation: as no magnetic field is generated, inductors suffer no heat dissipation. Secondly, the leakage is significantly lower thanks to a low value capacitance. Finally by using only one common inductor, these designs definitely save space.
Dr. Guillaume Aubard, Exxelia Filters’ Business Development Manager will be speaking at EMV Forum Hall C2-319 on March 20th from 3:40pm to 4pm about the Asymmetric filter solutions for HEMP and TEMPEST following by a Q&A.
Innovative RF/Microwave components at IMS - Booth# 635 -
Ultra low ESR, high RF power and high self-resonant frequency The 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. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking. 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 Q Factor Dielectric Resonators Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia has developed with support of ESA and CNES, a new high-end dielectric material, E7000 series, designed for high-end filters where high Q factor is requested. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q factor and the possibility to get all the temperature coefficients upon request. E7000 provides high-performance requested for space use in the frequency range 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Typical applications: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
Innovative new products at Electronica - Booth# B5 312 -
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. Ceramic capacitors based on the new C48X dielectric New 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. 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.
