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.
TCM Series of High-Reliability Common-Mode Inductors
Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries. The TCM series of common-mode chokes is designed into circuit boards of a large number of power electronic devices used for a wide range of applications, including switch-mode power supplies and converters, inverters, battery management systems, and chargers. Exxelia’s TCM series fully complies with the requirements of RoHS and REACH.
Low Voltage 0402 MLCCs now in ESA QPL
Exxelia ranges of low voltage MLCC for surface mounting, CEC19 and CNC19, have achieved the Qualified Part List (QPL) status under the criteria of the European Space Component Coordination’s (ESCC) 3009/042 and 3009/043 respectively. The case size 0402 QPL-qualified parts are available from 10V to 25V, enabling substantial miniaturization and cost-saving. Dielectrics are based either in the very stable NPO (type 1) or the high capacitance X7R (type 2). CEC and CNC series combine high capacitance values with high thermal and voltage stability. Versions with polymer terminations are also QPL-certified. These ranges of versatile chip capacitors are intended for use in a wide variety of aerospace applications requiring the highest level of reliability: satellites, launch vehicles, payloads, etc. CEC19 features: - very stable NPO dielectric - maximum capacitance values: 330pF in 10V, 120pF in 16V and 100pF in 25V, - large operating temperatures: -55°C to 125°C CNC19 features: - high capacitance X7R dielectric - high capacitance rating values: from 68pF to 12nF in 10V, 8.2nF in 16V and 5.6nF in 25V - large operating temperatures: -55°C to 125°C
