Resistors yog cov khoom siv hluav taws xob passive uas yog siv los tswj cov dej ntws ntawm cov tam sim no hauv ib lub voj voog los ntawm kev muab kev tiv thaiv.Lawv yog siv nyob rau hauv ntau yam ntawm hluav taws xob circuits, los ntawm yooj yim LED circuits mus rau complex microcontrollers.Lub luag haujlwm tseem ceeb ntawm tus resistor yog tiv thaiv qhov ntws ntawm tam sim no thiab ntsuas hauv ohms (Ω).
Hom ntawm resistors
Muaj ntau hom resistors ntawm kev ua lag luam, txhua tus muaj lawv tus kheej cov yam ntxwv thiab kev siv.Qee hom resistors feem ntau yog
Cov pa roj carbon sib xyaw ua ke: Cov resistors no yog tsim los ntawm cov khoom siv carbon thiab cov ntaub ntawv, yog molded rau hauv ib lub cylindrical zoo thiab coated nrog ib tug insulating khoom.Lawv yog cov tsis tshua muaj nqi thiab muaj ib tug siab kam rau ua rau kub variations.
Hlau zaj duab xis Resistors: Cov resistors no yog tsim los ntawm cov yeeb yaj kiab hlau uas tau tso rau ntawm cov khoom siv ceramic.Lawv muaj cov qib siab ntawm precision thiab ruaj khov, ua rau lawv haum rau siv nyob rau hauv precision circuits.
Wirewound Resistors: Cov resistors no yog tsim los ntawm cov hlau hlau qhov txhab ntawm ib tug ceramic los yog hlau core.Lawv muaj qhov ntsuas lub zog siab, ua rau lawv tsim nyog siv rau hauv cov ntawv thov tam sim no.
Surface Mount Resistors: Cov resistors no yog tsim los txuas ncaj qha rau saum npoo ntawm lub rooj tsav xwm luam tawm (PCB).Lawv yog cov me me thiab feem ntau yog siv hauv cov khoom siv hluav taws xob compact.
Resistor yam ntxwv
Cov yam ntxwv ntawm cov resistors sib txawv nyob ntawm seb hom resistor thiab daim ntawv thov.Qee yam tseem ceeb ntawm cov resistors muaj xws li:
Kuj:Qhov no yog tus yam ntxwv tseem ceeb tshaj plaws ntawm cov resistor thiab ntsuas hauv ohms (Ω).Tus nqi ntawm tus resistor qhov tsis kam txiav txim siab tus nqi tam sim no uas tuaj yeem dhau los ntawm nws.
Kev kam rau siab:Qhov no yog tus nqi ntawm qhov sib txawv ntawm qhov tseeb tsis kam ntawm tus resistor thiab nws tus nqi nominal.Kev kam rau siab yog qhia raws li feem pua ntawm tus nqi nominal.
Kev ntsuas fais fab:Qhov no yog lub siab tshaj plaws ntawm lub hwj chim ib tug resistor yuav dissipate yam tsis tau puas.Kev ntsuas hluav taws xob tau qhia hauv watts (W).
Kub Coefficient:Qhov no yog tus nqi ntawm qhov tsis kam ntawm ib qho resistor hloov nrog kub.Qhov kub coefficient yog qhia nyob rau hauv qhov chaw ib lab degrees Celsius (ppm / ° C).
Hauv cov ntsiab lus, cov resistors yog ib feem tseem ceeb ntawm cov hluav taws xob hluav taws xob thiab lawv cov yam ntxwv thiab hom yuav tsum tau ua tib zoo txiav txim siab thaum xaiv cov resistor tsim nyog rau ib daim ntawv thov.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom.Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Hauv kaum xyoo no, peb tus kheej tsim NeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 thiab lwm yam khoom siv SMT, uas muag zoo thoob plaws ntiaj teb.Txog tam sim no, peb tau muag ntau dua 10,000pcs tshuab thiab xa tawm mus rau ntau dua 130 lub teb chaws thoob ntiaj teb, tsim kom muaj lub koob npe nrov hauv kev ua lag luam.Hauv peb lub ntiaj teb Ecosystem, peb koom tes nrog peb tus khub zoo tshaj plaws los xa cov kev pab cuam muag khoom ntau dua, kev ua haujlwm siab thiab kev txhawb nqa zoo.
Peb ntseeg tias cov neeg zoo thiab cov neeg koom tes ua rau NeoDen yog ib lub tuam txhab zoo thiab tias peb txoj kev cog lus rau Innovation, Diversity thiab Sustainability kom ntseeg tau tias SMT automation yog siv tau rau txhua tus neeg nyiam nyiam nyob txhua qhov chaw.
