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.

Two new ranges of MIL-qualified 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. PHM 912, very high energy density film capacitors PHM 912 is a new standard series of film capacitors based on a novel metallized plastic film dielectric from Dupont Teijin®. The PHM 912 capacitors are specifically designed for DC filtering or energy storage. Very stable in both temperature and frequency, they are well-adapted for applications such as filtering in H.F. switch mode power supplies, DC link or decoupling. The range can withstand temperatures up to 155°C and up to 175°C in custom version. With their high energy density, these capacitors allow highly integrated power filters. Their compact construction results in a low ESR, ESL and excellent high current and frequency performances. The series provides 250V @68µF and 0,27µF @1000V. The PHM 912 series makes significant advances over previous technologies by combining the benefits of excellent temperature resistance with superior energy densities, making it one of the most compact capacitors on the market. Felsic HV, long lifetime and high voltage screw terminal aluminum electrolytic capacitor The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density combined with ultra-long lifetime. For instance, 6 800µF @450V fit into a volume of Ø77x220mm and can withstand 200,000 hours between 0 to 70° under 37Amps, which makes them the perfect choice for use in rolling stock traction systems or the CVS. The family also has one of the lowest ESR of its class with less than 10m0hms in most cases. Products are available for voltages from 160 to 450Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compactness.
NHB series - NPO dielectric
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.
