Ultra low ESR, high RF power and high self-resonant frequency                The new 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 Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia has developed with support of ESA and CNES, a new high-end dielectric material, E7000 series, designed for high-end filters where high Q factor is requested. 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 provides high-performance requested for space use in the frequency range 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Typical applications: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.

Exxelia SIC SAFCO celebrates its 100th anniversary !

Founded in 1921, SIC SAFCO, the historical brand of our electrolytic capacitors, is celebrating its 100th anniversary this year! We have come a long way since the creation of the Société Industrielle des Condensateurs (SIC)! In 1930, Louis Ségal, the founder of SIC, set up his company in Colombes, in the Hauts de Seine region of France, and presented a patent for the manufacture of a three-phase capacitor with insulated wound sheets.   In 1935, the French company for the manufacture of electrical capacitors (SAFCO) was born. SAFCO merged with SIC in 1954 to form the SIC SAFCO brand.  This is the beginning of a great adventure for SIC SAFCO which will launch several ranges of capacitors such as :  - The SNAPSIC range of aluminium electrolytic snap-in capacitors  - The CUBISIC range of aluminium electrolytic radial capacitors  - The FELSIC range of aluminium electrolytic capacitors with screw terminal Some changes for SIC SAFCO which inaugurates its new site in Saint Nazaire in 2011 then change of name in 2015 for Exxelia SIC SAFCO. In 2018, with the merger of Exxelia's French entities, Exxelia SIC SAFCO becomes Exxelia SAS. Let's finish with the last news of the brand: the release in 2021 of the CUBISIC SLP range of radial electrolytic aluminium capacitors.
