Yuav ua li cas xaiv cov pa roj hmab zoo ua yeeb yaj kiab tiv thaiv koj txoj kev lag luam
Kev nyiaj tau
Kev ua siab rau yog hais txog kev sib cav uas muaj peev xwm los ntawm lub resistor tus nqi nominal. Kev thev taus ntau yam los ntawm ± 0.1% rau ± 10%. Thaum koj xaiv lub resistor, cov kev tsim tawm tau cuam tshuam tau ntau yam kev ua tau zoo thoob plaws hauv kev tiv thaiv hauv koj lub Circuit Court. Daim ntawv thov precision yuav tsum tau qis dua qib.
Cov Kev Ntsuas Hluav Taws Xob
Powe ntaus nqi qhia txog qhov siab tshaj plaws lub zog tiv thaiv kev tiv thaiv tuaj yeem cuam tshuam yam tsis muaj kev puas tsuaj. Qhov no feem ntau ntsuas hauv watts (w). Rau cov ntawv thov heev, koj xav tau resistors nrog kev ntsuas hluav taws xob ntau dua.
Kub Coefficient
Ntsuas cov ntsuas kub yog ntsuas qhov tseem ceeb npaum li cas cov nqi tiv thaiv kev hloov pauv nrog qhov kub thiab txias. Yuam kev cuam tshuam nrog tsawg-kub coefficients yog qhov zoo rau ib puag ncig nrog kev hloov chaw kub.
Kuj muaj nqi
Lub txiaj ntsig tsis kam txiav txim siab qhov tseem ceeb tshaj plaws uas hla dhau ntawm Circuit Court. Xaiv qhov tseeb Kuj tus nqi tsis tshua muaj txiaj ntsig tias koj cov hluav taws xob ua haujlwm raws li npaj siab.
Xam tiv thaiv
Ohm txoj cai (v=ir) los xam cov nqi tiv thaiv raws li Circuit Court qhov chaw voltage thiab cov kev qhia tam sim no.
Tus nqi resistor
Yuam kev tawm los ntawm cov qauv tseem ceeb, yog li xaiv qhov ze tshaj plaws muaj tus nqi rau koj qhov kev thov tau xam hauv Ohms. Txiav txim siab siv ntau yam tsim tawm hauv koob los yog sib piv kom ua tiav qhov lus nug tsis kam. Txoj hauv kev no tuaj yeem pab koj ua tiav cov nqi ncaj qha ntawm tus resistor uas yuav tsis muaj nyob ua ib chav tsev.
Oxidation
Oxidation yog ib qho kev sib raug uas muaj kev cuam tshuam ntev. Cov txheej txheem oxidation pib txij ntawm qhov chaw ntawm lub resistor thiab maj tob rau sab hauv. Tus nqi tsis kam nce nce ntxiv tom qab oxidation. Thiab cov thinner cov yeeb yaj kiab kuj yog, qhov tseem ceeb tshaj plaws cov nyhuv oxidation yuav yog. Yog tias cov khoom siv organic (plastics, resins, thiab lwm yam) yog siv rau txheej lossis potting txheej, cov txheej txheem tiv thaiv yuav yog huab cua permeable lossis tau ntub. Txawm hais tias cov ntaub ntawv no tuaj yeem ua lub luag haujlwm hauv kev ncua oxidation lossis adsorbing roj, lawv tseem yuav nqa qee cov kev laus tshiab cuam tshuam nrog cov organic tiv thaiv txheej.

Yog tias muaj ntau ntawm noo noo nyob rau hauv ib puag ncig, qhov tsis muaj zog ntawm cov duab carbon uates yuav kuj oxidize, ua kom cov kua nplaum nyias thiab nce cov nqi tiv thaiv, thiab txawm qhib Circuit Court.
Roj Adsorption Thiab DeRorption
Thaum lub tshuab decomposed falbon firsted ua rau hauv lub tshuab nqus tsev ua haujlwm ncaj qha, nws yuav adsorb ib feem mus ncaj qha rau cov roj ib puag ncig, uas yuav ua rau tus nqi tiv thaiv cua. Yog tias cov khoom ua tiav ua tiav uas tsis tau ua tiav yog preset nyob rau lub sijhawm ua haujlwm nyob rau hauv ib txwm muaj siab, lub zog ruaj khov ntawm cov khoom lag luam uas ua tiav lawm.
Ntxeem tau (reflowed) carbon film
Cov yeeb yaj kiab yog tsis xws luag lossis poob qis, lossis muaj mobile ions zoo li na, k, cl, uas ua rau cov txheej tiv thaiv yog qhov tsis zoo.
Ua haujlwm ntawm cov pa roj carbon resors
Thaum tsim hluav taws xob hluav taws xob lossis hluav taws xob Circuit rau qee lub hom phiaj, qhov tseeb ntawm kev tiv thaiv kab ke hauv Circuit Court Board yuav tsum yog ntxias. Nws yog ua tiav los ntawm kev siv cov roj carbon resistors, uas yog cov khoom me me. Cov khoom siv no yog cov pob ntawv me me ntawm kev tiv thaiv uas tau txuas nrog lub Circuit Court kom txwv qhov ntws los ntawm tus nqi tshwj xeeb.
Cov pa roj carbon tau muab tso rau hauv cov tub ntxhais kab ke hauv cov carbon resistor. Cov pa roj carbon tso tawm yog etched nyob rau hauv ib tug kauv, uas hloov nws mus rau hauv ib lub coamer coiled rau ntawm ceramic core ceramic. Lub suab, lub cheeb, thiab ntev ntawm cov kab mob carbon kauv sib txawv raws li qhov yuav tsum tau ua. Nickel lub kaus mom txuas nrog ob qho kawg ntawm cov tseem ceeb kom ntseeg tau tias cov pa roj carbon thiab cov hmoov txhuas tau sib cuag zoo heev.
Cov Khoom Siv Yooj Yim: Carbon
Nyob rau hauv lub plawv ntawm txhua tus neeg siv hluav taws xob tiv thaiv yog nws cov khoom tseem ceeb: carbon. Cov ntsiab lus no yog muab tso rau hauv daim nyias nyias, txuas ntxiv ua yeeb yaj kiab ntawm qhov tsis-conductive substrate (feem ntau ceramic). Cov pa roj carbon cov khoom sib txawv ua rau nws zoo rau kev tswj tsis tau.Carbon muaj ntau qhov zoo raws li cov khoom siv tiv taus. Nws muaj lub siab melting taw tes thiab tsis muaj zog tshaj tawm, ua rau nws ruaj khov tshaj li ntau qhov kub.

Substrate
Substrate cov khoom siv feem ntau siv 96% ntawm lub alumina trioxide ceramic. Lub substrate yuav tsum muaj hluav taws xob hluav taws xob zoo nyob rau hauv tas li ntawd rau cov zoo thermal conductivity ntawm qhov kub. Cov khoom hluav taws xob thiab tshuab muaj zog thiab lwm yam ntxwv. Nws tseem raug tsim nyog tias lub substrate yog tiaj thiab yog scribed. Txheem rau siab ua kom pom kev. Hluav Taws Xob Muab Luam Ntawv Tso Rau Hauv Qhov Chaw.
Resistive Film
Luam tawm nrog cov tshuaj txhuam tiv thaiv nrog qee yam tiv taus mus rau cov ceramic substrate, thiab ces sintereded. Cov tshuaj txhuam tiv thaiv feem ntau yog ua los ntawm ruthenium dioxide.
Tiv thaiv zaj duab xis
Cov zaj duab xis tiv thaiv yog them rau ntawm cov yeeb yaj kiab tiv taus, feem ntau los tiv thaiv lub cev tiv taus. Nws plays lub luag haujlwm kho tshuab ntawm ib sab tes, thiab ua rau lub npoo resistor lub cev insulating rau lwm txhais tes kom tsis txhob ua tiav ntawm lub resistor los ntawm cov neeg nyob sib ze nrog kev sib koom ua ke nrog cov neeg nyob sib ze. Nyob rau hauv cov txheej txheem ntawm electro-kev hloov chaw nruab nrab hluav taws xob hluav taws xob, nws kuj txwv tsis pub cov yaig ntawm cov kua hluav taws xob uas ua rau qhov ua kua hluav taws xob uas ua rau muaj kev cuam tshuam ntawm kev ua tau zoo. Cov yeeb yaj kiab tiv thaiv feem ntau yog feem ntau melting point iav muab tshuaj txhuam, sintereded los ntawm luam ntawv.
Khoom siv hluav taws xob
Nws yog kom ntseeg tau tias lub resistor muaj zoo soldoldability thiab kev ntseeg tau. Feem ntau, ib qho txheej txheem electrode yog saws: sab hauv txheej, txheej nruab nrab txheej, thiab txheej sab nraud. Sab hauv txheej electrode yog sab hauv hluav taws xob txuas nrog lub cev tiv thaiv lub cev. Cov khoom siv hluav taws xob yuav tsum tau raug xaiv nrog cov khoom siv uas muaj kev sib chwv nrog ceramic tsis kam, thiab yog ib qho yooj yim ua cov haujlwm electroplating. Nws yog feem ntau ua los ntawm cov nyiaj-palladium alloy los ntawm kev luam ntawv thiab sintering. Qhov nruab nrab electrode yog ib txheej npib tsib xee, tseem hu ua ib txheej barrier. Nws muaj nuj nqi yog txhawm rau txhim kho cov cua sov ua kom tsis txhob ua rau muaj cov duab hluav taws xob tiv thaiv kab ke, thiab tiv thaiv cov khoom sib tsoo Lub sab nraud hluav taws xob tin-txhuas txheej tseem tau hu ua cov txheej singleable. Nws txoj haujlwm yog ua kom cov electrode muaj zoo solderability thiab txuas ntxiv kev pabcuam lub neej ntawm electrode. Nws yog feem ntau plated nrog tin-coj alloy.
