The highest q i have measured in very large inductors of optimum form factor in the hf range has been near 1000.

Inductor q minimum. What is srf self resonant frequency. The q of an individual reactive component depends on the frequency at which it is evaluated which is typically the resonant frequency of the circuit that it is used in. Alewin75 on may 11 2018.

The higher the q is the narrower the bandwidth of the resonant circuit. The quickest search for passives in the market today. Quality factor or q factor affects lc filter circuits in the same way that it does for inductors and capacitors.

Often inductors may be thought of as having a pure inductance whereas in reality they have some resistance. I am looking for guidance on calculating the minimum inductance required to prevent subharmonic oscillation on the lt8650. An inductor has low distributed capacitance between terminal electrodes or the turns of a wire wound conductor and its inductance with such distributed capacitance resonates at a certain frequency.

It is generally very important to ensure that the q is maintained at a sufficiently high levels for the circuit to provide adequate filtering. 100 mh fixed inductors are available at mouser electronics. High q inductors are used with capacitors to make resonant circuits in radio transmitters and receivers.

I was not able to locate the sx voltage ramp parameters for the 8650. Quickbuilder by nic components. An inductor q is a valuable quantity.

The q factor of an inductor is defined as where l is the inductance r is the dcr and the product wl is the inductive reactance. The q factor can be applied to an inductor just as it can to a resonant circuit containing inductance capacitance and resistance. Inductors coils inductors coils inductors coils a.

The q of an inductor with a series loss resistance is the q of a resonant circuit using that inductor including its series loss and a perfect capacitor. I found the mention of app note 19 which is an amazing reference and the details there. The highest q hf inductors i have measured at least when operated away from self resonance are copper tubing coils and edge wound inductors such as those commonly used in high power tank coils.
