WT83 - HIGH CAPACITANCE WET TANTALUM
With 470µf @100V in a D size, WT 83 is a pass to miniaturize your impactful miniaturization of existing or new designs!
Capacitance values have been strongly increased with Exxelia's new range of tantalum capacitors:
- WT83 is an extension of the ST79 families (according to CLR93 MIL values) but with double the capacitance. That is a pass for impactful miniaturization of existing designs by playing on both size and weight (for instance, WT83 offers 470µf 100V in a D size, whereas ST79 only gives 220µF in the same other conditions).

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.

State-of-the art absolute optical encoders Exxelia has acquired deep expertise in the development of contactless position sensors of several type: absolute and incremental optical encoders, magnetic technology and inductive sensors. Several ranges of state-of-the-art absolute optical encoders will be showcased at the company booth - Hall 5A booth# E543. Absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. They provide the highest resolution, operating speed reliability as well as long life operation in most demanding environments. Exxelia ranges of absolute optical encoders offer very high performance levels for a very small footprint: high precision (<30arcsc.), high resolution (up to 21 bits), extreme thinness (10mm) and EMI EMC compatibility. With their compact design, Exxelia miniature encoders meet the requirements of the most demanding application such as aerospace, defense, medical, oil & mining industries. Various protocols are available to match with any application. Exxelia encoders can be easily combined with other functions such as slip rings to provide customers turkey solutions. Two new ranges of MIL-qualified wet tantalum capacitors: MIL39006/22 & MIL39006/25 The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance.
