Hauv hluav taws xob engineering, zaus yog ib lub tswv yim zoo.
Hluav taws xob zaus yog hais txog qhov zaus ntawm kev hloov pauv nyob rau hauv qhov voltage thiab tam sim no nyob rau hauv alternating tam sim no, uas yog, cov kev taw qhia thiab loj ntawm tam sim no hloov ntawm ib tug tej zaus.
Resistance tus nqi ntawm aresistortuaj yeem sib txawv ntawm ntau zaus, uas feem ntau cuam tshuam nrog cov lus teb zaus ntawm cov khoom siv resistor. Feem ntau hais lus, cov khoom siv tiv thaiv feem ntau pom muaj tus nqi ruaj khov nyob rau hauv qhov tsawg zaus, tab sis raws li qhov zaus nce, qee qhov cuam tshuam yuav ua rau muaj kev hloov pauv ntawm tus nqi kuj. Cov hauv qab no yog qee yam uas yuav ua rau muaj kev cuam tshuam ntau zaus:
Cov nyhuv ntawm daim tawv nqaij:Nyob rau hauv high zaus, qhov tam sim no nyiam ntws los ntawm qhov chaw ntawm tus neeg xyuas pib es tsis yog los ntawm tag nrho cov hla ntu ntawm tus neeg xyuas pib. Qhov no yog hu ua Schottky effect, uas ua rau tus nqi kuj nce ntxiv nrog rau qhov ntau zaus.
Cov nyhuv sib thooj:Kev sib nrig sib inductance nyhuv yog ib qho tshwm sim uas tshwm sim ntawm cov neeg nyob ib sab ntawm cov zaus siab. Qhov no yuav ua rau muaj kev hloov pauv ntawm cov nqi tiv thaiv ze ntawm tus neeg xyuas pib, tshwj xeeb tshaj yog nyob rau hauv high-frequency AC circuits.
Cov nyhuv Capacitive:Nyob rau hauv high zaus, lub capacitive nyhuv ntawm resistive pab kiag li lawm yuav ua tau ib tug tseem ceeb, uas ua rau ib theem sib txawv ntawm tam sim no thiab voltage. Qhov no tuaj yeem ua rau tus nqi tiv thaiv kom pom cov impedance nyuaj ntawm cov zaus siab.
Dielectric Loss:Yog tias cov khoom siv hluav taws xob muaj cov khoom siv dielectric, cov ntaub ntawv no yuav ua rau poob ntawm qhov ntau zaus, ua rau muaj kev hloov pauv ntawm qhov tsis kam.
Hauv cov hluav taws xob hluav taws xob dav dav, qhov kev cia siab ntawm kev tiv thaiv feem ntau tsuas yog txiav txim siab hauv cov xov tooj cua zaus zaus (RF) circuits lossis cov ntawv thov tshwj xeeb. Rau feem ntau qhov tsawg zaus thiab DC daim ntawv thov, qhov cuam tshuam ntawm qhov tsis kam yog feem ntau negligible. Nyob rau hauv high-frequency circuits, tus tsim engineers yuav xaiv tshwj xeeb uas tsim los ntawm high-frequency resistor pab kiag li lawm kom tau raws li qhov yuav tsum tau muaj nyob rau hauv ntau zaus.

Thaum twgresistorsyog siv nyob rau hauv high-frequency xov tooj cua zaus (RF) circuits los yog tshwj xeeb high-frequency daim ntaub ntawv, kom tsis txhob muaj kev cuam tshuam ntawm zaus ntawm cov kuj, non-inductive resistors feem ntau yog xaiv.
Ceramic Resistor
Thick Film Resistors
ZENITHSUN tsim cov yeeb yaj kiab tuab thiab cov khoom siv hluav taws xob sib xyaw ua ke, ob qho tib si ntawm cov uas tsis yog-inductive resistors. Yog lawm, hlau qhov txhab resistors kuj tuaj yeem ua rau hauv hom inductance tsawg, tab sis cov nyhuv uas tsis yog inductive yog qis dua rau cov yeeb yaj kiab tuab thiab cov khoom siv ceramic. Qhov kev xaiv zoo tshaj plaws yog ceramic compositeresistors, uas txais yuav tsis yog-inductive tsim thiab muaj zog tiv thaiv mem tes muaj peev xwm.
