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 Ohmcraft Custom Resistors Help Ensure Reliability of Most-Deployed Anti-Tank Missile in the World

In times of warfare, the reliability of military weapons is absolutely critical to the success of a mission. For nearly a decade, military contractors have leveraged Exxelia Ohmcraft’s custom, high voltage resistors and dividers to ensure product performance in a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world. In a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world.“Missiles are exposed to extreme climate conditions and often sit idle—sometimes for several years—before they are launched. When that time comes, it is essential for those missiles to perform as expected,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Exxelia Ohmcraft custom resistors are designed to support the rigorous precision and reliability specifications required by military suppliers to withstand the harsh environmental conditions, ensuring that the missile remains fully operational under all circumstances. Exxelia Ohmcraft performs a full range of military lot acceptance testing (LAT) on resistors as necessary, and works closely with military contractors to meet the design requirements for each particular application. In the case of the FGM-148 Javelin, a small, lightweight form factor was imperative to keep the missiles as lightweight and portable as possible. Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

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
