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.

Exxelia expands its High-Performance Dielectric Resonators and Ferrites capabilities for Microwave Applications

New capabilities include the use of its latest E7000 material, which provides narrow bandwidths, temperature stability and high Q-factor together with advanced manufacturing skills such as the capability to deliver extremely small size, and complex ferrite designs.   Exxelia's E7000 series is a Ba-Mg-Ta based material that combines an ultra-high Q-factor and the possibility to get different temperature coefficients upon request. E7000 features the highest performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees a Qxf up to > 250 000 at 10GHZ. In addition, Exxelia is now able to support the most advanced RF designs with the delivery of complex geometries such as Y-shape ferrites for microwave switches or Toroidal designs for phase shifters applications. Those miniaturized and complex products may be as small as few mm only and benefit from exceptional quality, superior performance and low loss (ΔH) materials. Exxelia is a unique manufacturer producing its own raw materials for Ferrites and Dielectrics with proprietary formulations for use in the most demanding environments.   Nicolas Dabadie, Microwave Materials business development manager at Exxelia said: "We are pleased to support our customers’ more and more complex designs and demanding applications. Our unique capability to master the manufacturing from raw materials to high-end finished products opens the way to new solutions for microwave applications going from few MHz to 40GHz".     E7000 SERIES TECHNICAL SPECIFICATIONS : Dielectric constant : 24 Q x f Factor (GHz) : 250000 Frequency : Min : 5900 MHz / Max : 37150 MHz Custom shapes available : disk, cylinder, square etc… Typical Q factor: 25000 at 10 GHz   More information: https://exxelia.com/en/product/detail/636/e7000   Ferrite materials are used in microwave devices such as isolators, circulators, diplexers, filters and phase shifters. They have dielectric and magnetic properties due to the presence of magnetic ions such as iron within the composition. Exxelia also offers a wide range of dielectric resonators series, including coaxial resonators in different sizes. Please contact us for additional details !
