Electrode system optimised for lowest possible ESR

Electrode system optimised for lowest possible ESR
A new addition to the range of High-Q MLCCs has been released by Knowles Capacitors brand, Syfer. Designated as the “H” series they are manufactured from a very stable, X8G High Q ceramic dielectric to provide Ultra-low ESR, with excellent low loss performance and low power consumption, in high environmental temperature and high frequency systems. They exhibit no ageing effects, with stability under voltage and very low drift.

CapCad Take The Catwalk For Capacitor Modelling

Syfer Technology, is a web-based software package designed specifically to help designers select the optimum multilayer capacitor devices for their next design. Called CapCad, the software tool is easy and fast to use, and provides circuit designers with a readily accessible capacitor comparison facility. CapCad™ includes SPICE models with various parameter values that reflect typical performance at the chosen frequencies. Importantly, engineers can select the temperature range relevant to the application, and adjust it as necessary, to note how it may affect the expected performance of the design.
