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.
MIL 39006-Qualified Wet Tantalum Capacitors
Exxelia has received the M-Level (1.0%/1000h) MIL-PRF-39006/22 and MIL-PRF-39006/25 qualifications approval for its new ranges of wet tantalum capacitors. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature hermetically sealed cylindrical tantalum cases and axial leads. Both ranges are available in all cases: T1, T2 T3 and T4 with extended capacitance and voltage ratings. MIL39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @ 6V to 56 µF @ 125V. MIL 39006/25 is qualified for voltages from 25V to 125V and provides from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with large temperature ranges -55°C up to 125°C and are available with H vibration and shocks features. These state-of-art MIL-qualified wet tantalum capacitors are widely used in avionics applications where high performance and extreme reliability are required. Performance highlights compared to solid tantalum capacitors include more capacitance, higher ripple currents, lower ESR and lower dc-leakage current. “These new ranges introduction leverages our decades of experience in providing high-reliability capacitors for the Military market, and proves Exxelia’s ability to reach the most demanding specifications in terms of product development”, states Exxelia Sales & Marketing VP, Jérôme Tabourel, “We are proud to be part of the few MIL-qualified manufacturers of tantalum capacitors, our flexibility and advantageous lead times will bring new supply perspectives.” MIL39006/22 and MIL39006/25 are available for order now.
NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM
Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements. 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.
