Exxelia will exhibit the CCM series during the Applied Power Electronics Conference at Exxelia’s booth #623 from March 27-30, 2017 in Tampa, FL.
Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint.
Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204).
The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10.
CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating.
Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM
Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements. Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.
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
