Introduction of DSCC 93026 qualified Wet Tantalum Capacitors
Exxelia has received the qualification by the Defense Supply Center Columbus (DSCC) as an approved provider of WT84 wet tantalum capacitors under the drawing DSCC 93026.
Exxelia’s range of wet tantalum capacitors WT84 is now fully qualified to DSCC 93026 drawing for voltages from 25V up to 125V. Available in all case sizes (T1, T2, T3, T4) the family is housed in a hermetically sealed tantalum case and is designed to withstand the most stringent environmental constraints. Thanks to the continuous improvements conducted in the manufacturing processes combined with the high purity tantalum powder used by Exxelia, DSCC 93026 provides the highest capacitance per unit volume. In addition, compared to conventional wet tantalum capacitors, DSCC 93026 features much lower ESR and higher ripple current.
DSCC 93026 is qualified for capacitance values range from 10µF up to 1800µF at voltages from 25V up to 125V, and with operating temperatures of -55°C to 125°C. The series is ideal for use in high-reliability defense, avionics, radars and power supply applications requiring high capacitance or high energy storage.
DSCC 93026 is available now for order.
Exxelia MIL Wet Tantalum Capacitors M39006/22 now qualified to Level P
Exxelia MIL Wet Tantalum Capacitors M39006/22 now qualified to Level P June 24th, 2019 – Paris, France – Exxelia, a French leading global designer and manufacturer of high-rel passive components and sub-systems dedicated to harsh environments, has received the P-Level qualification approval for its Wet Tantalum Capacitors MIL-PRF-39006/22. Exxelia’s MIL 39006/22 equivalent to CLR79 series is now approved to P-level reliability (0,1% / 1,000 h) for voltage ranges from 6V to 125V with a capacitance value ranging from 1,7µF to 1200µF. Available in T1, T2, T3 and T4 case sizes, these products are housed in a hermetically sealed Tantalum case operating from -55°C to +125°C and are designed to withstand the most stringent environmental constraints. FEATURES: Qualified for voltages up to 125V Provides from 1200µF at 6V to 56µF at 125V Highest Energy Density Unlimited shelf life Available with H vibration and shocks Manufactured in France MIL 39006/22 Level P are now available for order with a 14 weeks lead-time.
Larger Batches of High Q-Factor Dielectric Resonators
Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. 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 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
