Ultra low ESR, high RF power and high self-resonant frequency The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking. 100% invar tuning screws with self-locking system   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. High Q Factor Dielectric Resonators in large batches Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication.

Exxelia unveils two brand new High Temperature Film Capacitors series operating up to 200°C

Exxelia unveils two brand new High Temperature Film Capacitors series operating up to 200°C June 30th 2020 - Paris, France - Exxelia, an established designer and manufacturer of complex passive components, resistors & sub-systems dedicated to harsh environments, launches its new 253P & 560P product series providing unmatched performances at high temperature.   253P series, the 200°C Film capacitor series with unmatched stability The PTFE 253P series is the most stable 200°C Film capacitor on the market with its unparalleled stability of <2,5% with capacitance from 0.22μF to 1μF under 250VDC to 800VDC. It offers the lowest loss characteristic (Tẟ) of all film technologies less than 0,1% at extreme temperatures (200°C) with excellent life performance in operations. The series offers great resistance to vibrations, shocks and to over voltage making it ideal for Oil & Gas applications as well as Defense and Civil Aviation. SPECIFICATIONS: Voltages from 250VDC to 800VDC Capacitance from 0.22μF to 1μF Standard Tolerance ±10%, ±5%* Operating Temperature -55°C to +200°C  560P Film Capacitor series, is a High Temperature Polymer operating up to 180°C Exxelia’s 560P product series combines electrical performance between BOPP & PET while exhibiting a higher operating temperature up to 180°C and longer lifetime, it is the perfect cost-effective solution for high reliability and performance in severe environments. With absolutely no derating up to 150°C, its very stable TCC <2,5% and its great resistance to vibrations, shocks and over voltage, the series supplant high temperature ceramics and tantalums being an ideal choice for many capacitor applications in harsh environments i.e. DC Link, AC Filtering, ....   SPECIFICATIONS: Voltages from 320VDC to 800VDC Capacitance value from 0.022μF to 10μF Standard Tolerance ±10%, ±5%* Temperature ranges from -55°C to +180°C   Both series are available with a high degree of customization (* tighter tolerances available upon request).
