Syfer, a Knowles Capacitors brand has made a new addition to their range of High-Q Multi-layer Ceramic Capacitors (MLCC). The H Series capacitors, are manufactured from a very stable, X8G High Q ceramic dielectric to provide Ultra-low ESR, with 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.
This electrode system is optimized 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 -55ºC to +150ºC accommodates modern high density microelectronics requirements where environmental temperature could be high. They can be used for DC blocking, Impedance Matching, Coupling and Decoupling functions of PA modules, LNA modules and Antenna systems in small cells or 5G networks - where environmental temperature is high as a result of high power generated in relatively small chambers. Automotive applications are also another area for potential use.
With the excellent ESR performance and extended temperature range, their H Series High Q MLCCs can contribute to improving power amplifier efficiency and long term reliability of systems - greatly reducing power loss, heat dissipation and decreased battery drain. These capacitors are currently available in 0603 and 0805 case sizes. A 0402 size will follow shortly.
