Carbide Resistor
Carbide resistors yog thaiv hom ua los ntawm cov khoom siv carbide uas tsim los ntawm kev sib xyaw cov hmoov carbon nrog hmoov ceramics lossis lwm yam khoom siv hluav taws xob kub-resistant hluav taws xob thiab cov organic binders. Cov hluav taws xob tam sim no ntws los ntawm lub vev xaib zoo li cov pa roj carbon monoxide uas sib cuag thoob plaws hauv cov khoom siv; los ntawm kev nce kev faib ua feem ntawm cov insulator siv, lub web conductive no ua finer thiab cov resistivity ntawm cov khoom nce. Cov piv txwv thaum ntxov tsuas yog ob lub xov hlau hluav taws xob ntawm lub tog raj kheej, uas tom qab ntawd pleev xim los qhia qhov tseem ceeb ntawm kev tiv thaiv thiab muab kev tiv thaiv qib. Cov piv txwv niaj hnub no feem ntau yog encapsulated nyob rau hauv phenolic resin vaj tsev uas muab lub mounting feature rau cov coj thiab ib lub thawv rau cov khoom carbide nrog cov yam ntxwv zoo ib yam li ib tug cwj mem.
Lawv tseem nyob hauv kev siv ntau xyoo nyob ib ncig ntawm 1960s rau tus nqi vim li cas, txawm hais tias qhov zoo dua tau ploj mus txij thaum ntawd los. Carbide resistors yog loj; niaj hnub no lawv tej zaum yuav muaj kaum npaug ntau dua li cov qib zoo sib xws hauv lwm cov thev naus laus zis. Lawv tsis meej. Cov piv txwv tam sim no muaj qhov kam rau ua tsawg li 5 feem pua, tab sis daim duab ntawd tsuas yog hais txog kev hloov pauv ntawm kev kam rau siab hauv kev tsim khoom. Nws tsis suav nrog lwm yam uas yuav cuam tshuam rau qhov ntsuas tus nqi ntawm cov khoom: av noo / av noo tuaj yeem ua rau muaj kev sib txawv ntawm qhov siab ntawm li 10 feem pua, thiab qhov kub thiab txias yuav ua rau muaj qhov sib txawv ntawm 10 feem pua. Vim yog cov rhiab heev, muaj qhov taw tes me me hauv kev sim kho lawv kom muaj nuj nqis thaum tsim khoom. Lawv yog cov siv thev naus laus zis ntau tshaj plaws thiab pom yuav luag tshwj xeeb hauv pob khoom los ntawm qhov. Cov pa roj carbon uas ua rau lawv cov muaj pes tsawg leeg yog flammable, yog li lawv feem ntau ntes hluav taws thaum lub sij hawm overloads los yog tsis ua hauj lwm, thiab lawv muaj ho txo qis siab tshaj plaws kev khiav hauj lwm kub dua li ntau lwm yam resistive technologies.
Txawm li cas los xij, vim lawv qhov thaiv kev tsim kho, carbide resistors yog cov khoom siv hluav taws xob zoo heev thiab zoo li tshwj xeeb rau kev siv siab, luv luv overload txheej xwm xws li electrostatic paug. Hauv qhov kev hwm no, carbide resistors feem ntau yog ib mus rau ob qhov kev txiav txim siab ntau dua li lwm cov thev naus laus zis. Nyob rau hauv qhov txwv ntawm lawv cov pob, lawv kuj muaj cov kab mob parasitic inductance tsawg, uas feem ntau xav tau nyob rau hauv cov xwm txheej cuam tshuam nrog kev hloov pauv sai. Rau cov kev siv tsawg uas cov kev ua tau zoo no muaj nuj nqis heev thiab lwm yam tsis xws luag tuaj yeem zam tau, cov pa roj carbon muaj pes tsawg leeg yog qhov kev xaiv tsim nyog. Txawm li cas los xij, feem ntau, lwm hom resistors yuav zoo dua rau daim ntawv thov.
Carbon Film Resistors
Carbon zaj duab xis resistors yog cov yeeb yaj kiab nyias ntawm cov khoom siv hluav taws xob uas tsim los siv cov pa roj carbon raws li cov khoom siv tiv thaiv. Ib qho kev txhim kho tseem ceeb ntawm carbide resistors yog tias: lawv tso qhov ntsuas hluav taws xob zoo txhawm rau txhim kho qhov tseeb, ruaj khov, miniaturization, thiab txhim kho cov yam ntxwv suab nrov tam sim no. Lwm cov yeeb yaj kiab nyias hom resistors yuav mus ntxiv rau hauv cov kev taw qhia no, lossis ua li ntawd thaum tau txais tus nqi zoo dua, uas tej zaum yuav yog qhov kev xaiv zoo tshaj plaws rau cov qauv tsim tam sim no. Ib feem ntawm qhov kev nyiam no kuj yog vim qhov tseeb tias cov pa roj carbon ntau yog flammable, thaum cov kev xaiv dav dav tsis tshua muaj hluav taws kub, thiab nws yog qhov zoo heev kom tsis txhob muaj hluav taws kub thaum muaj teeb meem nrog cov khoom.
Qhov nrov ntawm carbon zaj duab xis resistors zoo li yuav txo qis raws li qhov muaj koob meej ntawm cov hom los ntawm qhov nce. Thaum lub sij hawm tom kawg tseem siv, thiab lwm hom nyias zaj duab xis resistors tam sim no muaj nyob rau hauv cov pob los ntawm lub qhov, nto mount carbon zaj duab xis resistors yog tsawg.
Ceramic Resistor
Ceramic resistors yog raws li lawv cov kev siv cov resistors tsim los ntawm cov khoom siv ceramic los yog cov khoom siv ceramic, uas txawv ntawm lwm hom resistor uas yuav siv cov ntaub ntawv ceramic hauv lawv cov kev tsim kho, tab sis tsis yog cov khoom tseem ceeb los ntawm cov khoom tam sim no. Lawv yog cov block resistor zoo ib yam li carbide resistors, nrog cov mem tes-tiv taus, tsis yog inductive yam ntxwv. Qhov tseeb, txij li cov hmoov ceramics feem ntau yog siv los ua ib feem ntawm carbide resistors, muaj qhov sib tshooj ntawm ob qho tib si ntawm kev faib tawm. Txawm li cas los xij, kev sib txawv tuaj yeem ua raws li cov khoom siv hluav taws xob siv thiab txoj hauv kev uas cov khoom sib xyaw ua ke; carbide resistors tsuas yog siv cov pa roj carbon monoxide los ua cov khoom siv nruab nrab thiab tau koom ua ke siv cov organic binder, thaum cov khoom siv hluav taws xob tuaj yeem muaj lwm yam khoom siv xws li hlau lossis hlau oxides thiab tau koom ua ke los ntawm sintering lossis kub yaj txheej txheem. "Cermet" (hlau ceramic) yog lo lus feem ntau siv rau cov khoom siv hauv potentiometers. Ceramic resistors muaj peev xwm ua haujlwm ntawm qhov kub siab dua li cov carbide resistors lawv hloov, txawm hais tias lawv kuj zoo li pom qhov kub coefficient ntau dua; kev sib xyaw ua ke uas feem ntau txhais mus rau hauv kev sib txawv ntawm qhov sib txawv ntawm li 30 feem pua ntawm cov khoom lag luam. Yog li ntawd, lawv tsis tsim nyog rau kev siv cov teeb liab me me thiab yog li ntawd feem ntau yog siv rau hauv cov ntawv thov nrog lub zog ntsuas ntau dua li tsawg kawg 1 watt.
Hlau Element Resistor
Resistors nrog "hlau" tivthaiv siv cov khoom loj ntawm cov khoom siv hlau ua cov khoom siv tiv thaiv thiab feem ntau yog siv rau kev tiv thaiv zoo hauv qab 1 ohm. Lawv feem ntau yog siv rau hauv daim ntawv thov kev ntsuas tam sim no qhov twg qhov ruaj khov, paub tus nqi qis resistor tuaj yeem ntsuas qhov loj tam sim no yam tsis ua rau muaj hluav taws xob ntau dhau thiab lub zog poob. Feem ntau hu ua shunt resistors (shunt), lawv feem ntau muaj 4-lead txiav rau Kelvin-hom kev ntsuas, yog li tso cai rau qhov hluav taws xob tam sim no thoob plaws lub resistor ntsuas nrog tsawg cuam tshuam los yog yuam kev nrog lub interface resistor ntawm cov khoom sib txuas. taw tes.
Hlau zaj duab xis Resistors thiab nyias zaj duab xis Resistors
Hlau zaj duab xis resistors thiab nyias zaj duab xis resistors yog ua raws li cov txheej txheem tsim khoom zoo sib xws nyob rau hauv uas cov khoom tiv thaiv yog tsim los ntawm nyias (feem ntau micron-loj) txheej txheej ntawm cov hlau siv rau cov txheej txheem ceramic los ntawm cov txheej txheem vapor deposition thiab tom qab ntawd txiav mus rau qhov xav tau. tus nqi. "Qhov sib txawv ntawm cov yeeb yaj kiab hlau resistors thiab nyias zaj duab xis resistors zoo li yog ib qho ntsiab lus; nyob rau hauv lub qhov resistors, "hlau zaj duab xis" resistors zoo li ntau dua, qhov twg carbon zaj duab xis resistors yog lwm txoj kev, thaum nyob rau hauv nti hom resistors, "tuab. zaj duab xis" yuav yog ib qho kev hloov pauv, thaum "thin film" zoo li yog qhov kev xaiv zoo tshaj plaws. "Thin film" zoo li yog lub ntsiab lus nyiam rau cov khoom lag luam tsom, thaum "hlau zaj duab xis" zoo li feem ntau siv rau kev siv lub hom phiaj.
Piv nrog rau cov khoom siv carbon zaj duab xis, hlau zaj duab xis resistors / zaj duab xis resistors tau ua ntxiv mus rau qhov tseeb, ruaj khov thiab suab nrov ua haujlwm, uas feem ntau kuj txhais tau tias cov nqi ntxiv rau cov xwm txheej surge. Tag nrho cov khoom loj ntawm cov khoom tiv thaiv yog me me txaus los ua rau cov khoom zoo li no cuam tshuam rau kev puas tsuaj los ntawm electrostatic paug, thiab cov pob me me thiab cov txiaj ntsig zoo dua tuaj yeem ua rau muaj kev puas tsuaj ntawm electrostatically induced. Cov khoom me me no kuj ua rau nyias zaj duab xis resistors tshwj xeeb tshaj yog raug rau tshuaj tua kab mob, vim qhov poob ntawm cov khoom me me los yog los ntawm kev hloov tshuaj lom neeg ua rau tsis ua haujlwm. Zuag qhia tag nrho, nyias zaj duab xis / hlau zaj duab xis resistors yog cov thev naus laus zis ntawm kev xaiv rau cov ntawv thov uas xav tau qhov tseeb thiab qhov ntsuas kev ruaj ntseg ntawm tus nqi qis. Tshwj xeeb tshaj yog nyob rau hauv daim ntawv nto mount pob, lawv kuj nyiam rau lawv cov yam ntxwv inductance tsawg thiab feem ntau siv nyob rau hauv kev kub ceev circuits.
Zhejiang NeoDen Technology Co., Ltd. tau raug tsim thiab xa tawm ntau yam me me thiab qhov chaw tshuab txij li xyoo 2010. Ua kom zoo dua ntawm peb tus kheej muaj kev paub txog R&D, kev cob qhia zoo, NeoDen yeej lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
