Ib tug varistor yog ib tug resistor nrog nonlinear volt-ampere yam ntxwv.Zoo li lub thermistor, nws yog ib qho khoom siv tsis muaj kab.Varistor yog rhiab heev rau voltage.Nyob rau hauv ib tug tej yam voltage range, nws kuj hloov nrog kev hloov ntawm voltage.
Varistorstau dav siv hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob, kev lag luam thiab lwm yam kev lag luam los ntawm kev tsim txiaj ntawm lawv tus kheej zoo.Piv txwv li, microwave ncu, cua txias, thiab lwm yam txhua yam muaj varistors.Kev khiav hauj lwm kub ntawm varistor yog -40 ° C ~ + 85 ° C.Varistor muaj kev ua haujlwm ruaj khov.Tom qab nws ua haujlwm tsis tu ncua rau 1000 teev ntawm qhov kub ntawm +40 ° C (± 2 ° C) thiab cov av noo ntawm kwv yees li 90%, thiab tom qab ntawd hloov mus rau qhov kub thiab txias, qhov hloov pauv ntawm qhov ntsuas varistor tsawg dua. 10%.
Nrog rau lub caij ntuj sov tuaj txog, qhov kub thiab txias tau nce siab dua, thiab varistor tuaj yeem muaj teeb meem thaum ua haujlwm kub.Qhov tseeb, tsis muaj teeb meem nrog lub varistor ua haujlwm ntawm qhov kub thiab txias rau lub sijhawm luv luv.Thaum lub varistor ua haujlwm nyob rau hauv qhov kub thiab txias ntev ntev, qhov qis-resistance linearization ntawm varistor maj mam intensifies, lub to tam sim no nce thiab ntws mus rau hauv lub tsis muaj zog point, thiab cov khoom ntawm cov tsis muaj zog point melts los tsim ib tug luv luv-circuit qhov. , ib tug loj tam sim no yog tsis tu ncua poured rau hauv lub luv luv-circuit qhov los ua ib tug high tshav kub, uas yuav ua rau lub varistor hlawv tawm thiab ntes hluav taws.
Yog li ntawd, thaum siv cov cuab yeej siv hauv tsev, tshwj xeeb tshaj yog cov khoom siv hluav taws xob siab, peb yuav tsum tau ua tib zoo saib xyuas qhov kub thiab txias nyob ib puag ncig cov khoom siv kom tsis txhob siab dhau, thiab tswj qhov kub thiab txias kom tsis txhob muaj xwm txheej txaus ntshai.
Xaiv lub chaw tsim khoom txhim khu kev qha thaum yuav varistor tuaj yeem zam ntau yam teeb meem tsis tsim nyog.JYH HSU (los yog Dongguan Zhixu Electronics) tsis tsuas yog muaj tag nrho cov qauv ntawm ceramic capacitors nrog lav zoo, tab sis kuj muaj kev txhawj xeeb tom qab muag.JEC cov chaw tsim khoom tau dhau ISO9001: 2015 kev tswj hwm kev tswj hwm daim ntawv pov thawj;JEC kev nyab xeeb capacitors (X capacitors thiab Y capacitors) thiab varistors tau dhau daim ntawv pov thawj ntawm ntau lub teb chaws;JEC ceramic capacitors, zaj duab xis capacitors thiab super capacitor yog nyob rau hauv txoj kab nrog qis carbon ntsuas.
