Dab tsi yog qee qhov teeb meem nrog cua coil inductors thiab lawv cov kev daws teeb meem?

Nws kuj raug cov kab mob parasitic capacitance nrog tsis xav tau resonance thiab microphonic los ntawm kev co. Cov kev daws teeb meem suav nrog kev ruaj ntseg winding, qhov sib nrug los yog toroidal core rau qis dua capacitance, thiab cov khoom uas ua rau muaj kev vibration.

Yuav ua li cas yav tom ntej trends yuav tsum nyob rau hauv cua coil inductortsim?

High-frequency cua coil inductor tsim uas yuav dhau los ua ntau dua yav tom ntej muaj xws li miniaturization nrog kev ua haujlwm siab, kev tsim cov khoom siv nrog txo qis zog ntawm cov zaus siab, thiab kev tsim kho tshiab rau kev txhim kho cua sov. Cov kev txhim kho no yog tsim los txhawb kev sib koom ua ke hauv cov khoom siv me me thaum tswj kev ua haujlwm thiab kev siv hluav taws xob.
