MIL Spec 39006, Now available in LEVEL R

Exxelia, global manufacturer of complex passive components and subsystems for harsh environments, is expanding its line of MIL-PRF-39006/22 & MIL-PRF-39006/25 tantalum capacitors, with the support of the reliability level R. MIL-PRF-39006 tantalum capacitors equivalent to CLR79 and CLR81 series: this is the new range of gelled tantalum capacitors meeting the standards required by the US Department of Defense in the manufacturing of components (compatibility & reliability).   Exxelia now offers reliability level R, in addition to level M and P for voltage ranges from 6 V to 125 V with capacitance values ranging from 1.7 µF to 1 200 µF. Available in all package sizes (T1 to T4), these fully sealed products are designed to operate at temperatures ranging from -55°C to +125°C and withstand the harshest environmental conditions. Performance highlights over solid tantalum capacitors include higher energy density, higher ripple currents, lower ESR and lower DC leakage current. Engineers with complex design requirements looking for a product that can be easily integrated into projects such as power supplies & converters or filtering units for the aerospace and defense industries will be pleased.  MIL 39006/22 & MIL 39006/25 Level R are now available for order with a lead time of 14 weeks.   "The introduction of these new ranges builds on our decades of experience in supplying high reliability capacitors to the military market and demonstrates Exxelia's ability to meet the most demanding specifications in terms of product development" says Jerome Tabourel, Exxelia's vice president of sales and marketing. "We are proud to be one of the few MIL qualified tantalum capacitor manufacturers, and our flexibility and advantageous lead times will bring new supply opportunities."   TECHNICAL CHARACTERISTICS Capacitance from 1.7 μF to 1,200 μF Voltage from 6 V to 125 V Operating temperature -55°C to +125°C Very good shock and vibration resistance (option H available)   Download the complete datasheet    

EXXELIA, A EUROPEAN SOURCE OF HIGH Q FACTOR DIELECTRIC RESONATORS

Operating frequencies in wireless communications have shifted towards high frequency band and thus frequencies higher than 1 Ghz are now commonly utilized. In addition, the microwave frequency spectrum becoming severely crowded and sub-divided into many different frequency bands, designers are systematically looking for resonators giving them a narrow bandwidth with smaller size. Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia Temex, daughter company of Exxelia Group, 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),
