MIL 39006-Qualified Wet Tantalum Capacitors
two new ranges of wet tantalum capacitors qualified to MIL 39006/22 and MIL 39006/25.
MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature hermetically sealed cylindrical tantalum cases and axial leads. Both ranges are available in all cases: T1, T2 T3 and T4 with extended capacitance and voltage ratings.
MIL39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @ 6V to 56 µF @ 125V. MIL 39006/25 is qualified for voltages from 25V to 125V and provides from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with large temperature ranges -55°C up to 125°C and are available with H vibration and shocks features.
These state-of-art MIL-qualified wet tantalum capacitors are widely used in avionics applications where high performance and extreme reliability are required. Performance highlights compared to solid tantalum capacitors include more capacitance, higher ripple currents, lower ESR and lower dc-leakage current.
“These new ranges introduction leverages our decades of experience in providing high-reliability capacitors for the Military market, and proves Exxelia’s ability to reach the most demanding specifications in terms of product development”, states Exxelia Sales & Marketing VP, Jérôme Tabourel, “We are proud to be part of the few MIL-qualified manufacturers of tantalum capacitors, our flexibility and advantageous lead times will bring new supply perspectives.”
QPL CERTIFICATION for PM907S & PM948S SERIES OF FILM CAPACITORS
Series PM907S and PM948S of Film capacitors obtained the QPL certification from the European Space Components Coordination (ESCC). According to the ESCC Detail Specification No. 3006/025 and 3006/026 QPL certified products ensure superior performances, quality and reliability intended for use by the European Space Agency (ESA) and in Space in general. PM907S and PM948S are full series of Polyester Film Capacitors. PM907S products are suitable for voltages from 50V up to 1250V and offer capacitance values from 82nF up to 180μF. PM948S can be used with a voltages from 50V up to 630V with capacitance values from 22nF up to 47μF. Both series can support extreme conditions with temperatures from -55°C to +125°C, and offer high energy density, low ESR & ESL and high RMS current. Products are typically being used in SMPS (Switch Mode Power Suppliers) and BUS filtering. These two certified series complete the list of Exxelia Group’s QPL certified film capacitors, that now includes: – PM90S – PM907S – PM96S (T) – PM94S – PM948S – MKT5 – KM111S – KM94S
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.
