Exxelia Releases Innovative New Products at electronica
Exxelia will be showcasing several of innovative new product ranges including aluminum electrolytic capacitors, chokes and ceramic capacitors. The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For example products can withstand 8000 hours at 105 degrees C under high values of current which makes them suitable for railway equipment. The family also has one of the lowest ESR for aluminum capacitors, less than 10m0hms in most cases. Products are available for voltages from 160- to 450-Vdc, and offer capacitance values from 1500µF up to 47000µF. Thus the family is a good compromise between reliability and compactness, with for example 47000µF at 160V in a 90x200mm volume.
Designed and qualified for aerospace, the TCM series is available in a through-hole package for horizontal and vertical mounting. TCM common-mode chokes are offered with inductances from 0.7 to 47mH under rated currents from 0.3A to 4A, and thoroughly tested by a dielectric withstanding strength at 1500Vac. Their excellent thermal properties allow the TCMs to operate without a hitch from -55 up to +125 degrees C, which, combined to the high mechanical resistance of the chosen materials (all meeting to UL94 V0 rating), make those products the perfect fit for aviation, defense and transportation industries.
New range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to achieve the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10-4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric are suited for power applications where heat dissipation may be detrimental to performances and reliability.
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 degrees 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.
