Hais txog Resistors thiab nws Hom
Qhov tseem ceeb ntawm Resistor:
Qhov no yog ib qho passive ob-terminal hluav taws xob tivthaiv uas siv hluav taws xob tiv thaiv ntawm ib lub voj voog. Lawv yog siv rau hauv kev siv cua sov thiab teeb pom kev zoo. Lawv pab tswj tus nqi tam sim no hauv ib lub voj voog. Hluav taws xob circuits yog tsim los ntawm resistors, transistors, capacitors, inductors thiab diodes. Nrog rau tag nrho cov khoom sib koom ua ke, cov hluav taws xob hluav taws xob muaj peev xwm ua haujlwm nyuaj. Cov teeb liab tuaj yeem nthuav dav, suav tuaj yeem ua tau thiab cov ntaub ntawv tuaj yeem txav los ntawm ib qho mus rau lwm qhov. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob. Kev ua haujlwm siab txhais tau hais tias muaj tsawg dua tam sim no rau qhov muab hluav taws xob. Txoj kev ntawm txoj haujlwm no yog los ntawm kev xa hluav taws xob hluav taws xob mus rau hauv tshav kub. Txoj kev uas lawv muaj peev xwm tig tau cua sov rau hauv lub zog yog los ntawm kev sib tsoo ntawm cov electrons thiab ions hauv lawv thaum lawv nqa tam sim no. Lawv hloov hluav taws xob hluav taws xob mus rau hauv cov khoom siv hluav taws xob xws li hlau, toasters, cov khoom siv hluav taws xob, cov tshuab ziab plaub hau thiab yuav luag txhua hom kev tsim hluav taws xob.
Feem ntau thiab yooj yim muaj hom:
Muaj ntau ntau hom resistors tab sis cov resistors hauv qab no feem ntau:
Cov pa roj carbon resistor- Cov hom no feem ntau yog cov roj carbon resistors uas yuav luag siv rau txhua lub hom phiaj thiab tseem pheej yig. Lawv hu ua carbon resistors vim lawv yog tsim los yog ua los ntawm carbon. Lawv yog tsim nyob rau hauv txawv qhov ntau thiab tsawg thiab nrog txawv zog dissipation txwv. Feem ntau hom resistors muaj li ntawm 1 mus rau 1/8 watt.Zaj duab xis resistor- Lawv muaj kev kam rau siab dua li cov khoom sib xyaw ua ke. Lawv hnov mob ntau dua hauv cov khoom siv hluav taws xob uas lawv tau siv hauv. Qee qhov chaw tsim khoom uas nqa cov yeeb yaj kiab yog American Technical Ceramics, Arcola, BI Technologies, Bourns, Caddock, Panasonic thiab Parallax. Cov khoom sib txawv ntawm cov yeeb yaj kiab yog: Carbon film resistors, hlau zaj duab xis resistors, planar resistors, tuab zaj duab xis resistors, thiab nyias zaj duab xis resistors.Hlau khi resistors- Lawv zoo ib yam li zaj duab xis hom resistor. Lawv yog tsim los ntawm wrapping ib daim hlau hlau nyob ib ncig ntawm ib daim ntawm insulated ceramic. Kev siv cov hlau bound resistors yog rau qhov kub thiab txias ntawm lub zog siab.
Txhua yam yog xim coded ces nws ua rau nws yooj yim rau liab. Cov xim coding qhia tias qhov no yog cable ua dab tsi. Qhov loj dua uas muaj qhov kam rau ua tus nqi ntawm qhov tsis kam thiab qhov ntsuas ntawm wattage luam tawm ntawm sab. Cov resistors me me qhia tias lawv cable ua dab tsi los ntawm cov xim.
Koj tuaj yeem xauj hauv lub vev xaib rau tus thawj coj faib khoom ntawm txhua hom Resistors Parts los ntawm cov npe dav dav ntawm cov tuam ntxhab. Ntawm qhov chaw no uas koj tuaj yeem tau txais tus nqi qib 1 los ntawm cov tuam txhab lag luam uas tau xaiv cov nyiaj khaws cia rau koj.
