Knowles Precision Devices High Q Capacitors High-Q

The Need For High Q Capacitors 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). Read about Q in the context of capacitors in general in our article on Capacitor Basics. Explore the importance of Q and ESR in our article on ESR measurement. Knowles Precision Devices offers devices based on a wide variety of High Q dielectrics including ultra-low ESR, high temperature, high power, ultra-stable and leaded options.
