High-Q MLC Capacitors
Knowles’ capacitors are available in chip or ribbon-leaded formats
Knowles offers devices based on a wide variety of high-Q dielectrics including ultra-low ESR, high-temperature, high-power, ultra-stable and leaded options. A high Q value indicates low energy loss during operation, making these capacitors a good fit for applications requiring low power dissipation and high stability.
As operational frequency requirements increase, electronic systems downsize and power usage becomes more critical, the most important parameters are Q (quality factor) and ESR (equivalent series resistance).
