The “H” series is manufactured using a very stable, X8G High Q ceramic dielectric that is able to provide ultra-low ESR, low loss performance and low power consumption. It can be used in high environmental temperature and high frequency systems.These MLCCs exhibit no ageing effects, with stability under voltage and very low drift.
The electrode system has been optimised for the lowest possible ESR and provides low metal losses that result in flatter performance curves and reduced losses at higher frequencies.
An extended operating temperature range of -55C to +150C accommodates modern high density microelectronics requirements where environmental temperature could be high.
According to Knowles they will be suitable in DC blocking, Impedance Matching, Coupling and Decoupling functions of PA module, LNA module and Antenna system of small cell or 5G networks - where environmental temperature is high as a result of high power generated in relatively small chambers. Automotive applications could also be another area of potential use.
With improved ESR performance and an extended temperature range, Syfer’s ‘H’ series High Q MLCCs can help to improve both power amplifier efficiency and the long term reliability of systems - greatly reducing power loss, heat dissipation and decreased battery drain.
0603 and 0805 case sizes are released with immediate effect with 0402 size following shortly.
