Sib sib zog nqus ntsaub mus rau ob hom
1. Cast -} ua yeeb yam fuses
Lub vas nthiv - Ua yeeb yam los qhib Circuit Court li sai tau thaum nws cov kev ntaus nqi tam sim no tau dhau mus.
Nws ua haujlwm li cas:Nws siv ib daim ntawv luv lossis luv ntawm cov khoom fuse. Thaum cov rated tam sim no tau dhau lawm, cov ntsiab lus no ua kom sov thiab melts yuav luag tam sim ntawd vim nws qhov qis thermal loj.
Cov yam ntxwv tseem ceeb: tsawg i²t.Tus "I²t" tus nqi sawv cev rau -}} los ntawm lub zog. Ib qho nqi qis txhais tau tias lub fuse kev txhaum sai heev, txwv qhov kev ua kom muaj zog uas mus txog hauv Downstream Cheebtsam.
Thaum xaiv lub vas nrawm - ua yeeb yam 3216 fuse:
Tiv thaiv cov khoom siv hluav taws xob rhiab:Koj tus naj npawb ib puas siv rooj plaub. Qhov no suav nrog:
Microcontrollers, FPGAS, ASICS
Fais fab tswj ics (pmics)
LED cov tsav tsheb thiab LED arrays(uas tuaj yeem ua kom puas los ntawm kev ua kom me dua).
Circuits nrog tsis muaj Inrush tam sim no:Nyob rau hauv cov roj teeb -} logic logic lossis digital logic circuits qhov twg cov haujlwm tam sim no yog ruaj khov thiab tsis muaj lub zog loj lossis lub cev ua rau pib ua haujlwm.
Qhov chaw ua txhaum yuav tsum nres tam sim:Txhawm rau tiv thaiv cov cascading swb uas ib qho tivthaiv tivthaiv qhov tsis ua kev puas tsuaj rau lwm tus.
Piv txwv li:Koj muaj cov tsheb ciav hlau 3.3V hluav taws xob pub rau microcontroller rhiab. MCU kos ib tug khov kho qib 100moos max. Koj yuav siv aCast - ua yeeb yam 3216 fuse rau 150mA lossis 200maYuav kom ntseeg tau tias nws blows tam sim ntawd yog tias luv luv tshwm sim hauv MCU, tiv thaiv tus so ntawm lub rooj tsavxwm 3.3V net.
2. Qeeb {{- tshuab (lub sijhawm -} qeeb) fuses)
Qeeb qeeb - tshuab fuse yog tsim los kom muaj kev tiv thaiv luv, thaum tseem muaj kev tiv thaiv kev tiv thaiv kev tawm tsam thiab luv luv.
Nws ua haujlwm li cas:Nws siv ib lub caij nyoog ntau dua, feem ntau yog lub caij nplooj ntoo hlav - zoo li qauv lossis cov khoom siv sib xyaw nrog cov cua sov {}}} nqus tau loj (nyiam sib xyaw). Cov surges luv tsis yog tsim kom muaj cua sov txaus kom yaj lub ntsiab lus, tab sis kev txhawb nqa ntau dua.
Cov yam ntxwv tseem ceeb: Siab I²t.Qhov siab siab cia -} los ntawm lub zog uas yog nws lub peev xwm los tiv thaiv cov spikes tam sim no.
Thaum twg los xaiv qeeb - tshuab tshuab 3216 fuse:
Circuits nrog siab inrush tam sim no:Qhov no yog qhov feem ntau vim li cas. Piv txwv li:
Lub cev muaj zog pib - up:DC Cov Motors muaj lub stall / pib tam sim no.
Capacitive loads:Loj loj cuam tshuam hluav taws xob ntawm cov khoom siv hluav taws xob kos cov kev tawm tsam kos ib qho kev nce qib uas lawv them. Yog tias tsis muaj qhov qeeb - tshuab fuse, lub Circuit Court yuav tsis tig rau.
Transformer cakeush:Thaum twg transformer yog thawj erergized, nws tuaj yeem kos lub caj dab tam sim no ntau zaus nws ua haujlwm tam sim no.
Inductive thauj khoom:Circuits nrog relays lossis solenoids uas tsim cov voltage spikes thaum muab tawm (tab sis TVs dodes desent kuj xav tau ntawm no rau kev voltage supression).
Piv txwv li:Koj muaj 12V tsheb ciav hlau muaj hwj chim kiv cua me me (ARC tsav). Tus kiv cua khiav ntawm 250mA tab sis muaj kev pib pib hauv 1.5A rau 50ms. Ib qho 400mA sai {{}} ua yeeb yam fuse yuav tshuab txhua zaus koj muaj hwj chim rau. Ibqeeb - tshuab 400ma 3216 fuseYuav muaj los ntawm kev pib tshaj tawm tab sis tseem muaj kev tiv thaiv yog tias lub cev muaj zog thiab rub cov 500mA txuas ntxiv.
Cov tseem ceeb tshaj plaws dhau kev nrawm (qhov tseem ceeb rau 3216 xaiv)
Rau 3216 hneev ko taw, chaw tsawg, yog li cov kev ntsuas yog qhov tseem ceeb:
1. Rated tam sim no (hauv):Tam sim no lub fuse tuaj yeem nqa tas mus li tsis muaj qhib.Tsis txhob tsis meej pem qhov no nrog hloov mus tam sim no!Txhua zaus yuav tsum tau - tus nqi me ntsis (piv txwv li, siv 100 fuse rau 800mA Max xav tau tam sim no).
2. Cov Ntsuas Hluav Taws Xob (AC & DC):Qhov ntau tshaj plaws hluav taws xob cov fuse yuav muaj kev cuam tshuam ruaj ntseg. Tshaj li qhov no tuaj yeem ua rau arcing thiab tiv thaiv kev fuse los ntawm kev tshem kom nyab xeeb. Xyuas kom koj lub dc rail voltage nyob qis dua cov ntaub ntawv fuse dc voltage ntsuas.
3. Breaking muaj peev xwm (cuam tshuam qhov ntsuas):Qhov kev txhaum ntau tshaj plaws tam sim no lub fuse yuav muaj kev cuam tshuam nyab xeeb. Rau me me 3216 fuses, qhov no feem ntau tsuas yog 50A. Yog tias koj lub zog siv hluav taws xob (zoo li roj teeb loj lossis AC / DC adapter) tuaj yeem xa ntau pua ntawm lub peev xwm tsis muaj peev xwm ua txhaum cai kom huv. Txheeb xyuas koj qhov peev xwm lub peev xwm luv- Circuit Court tam sim no.
4. I²t Rating Ntsuam Xyuas:Raws li tau sib tham, qhov no yog koj cov lej zoo tshaj plaws rau kev sib piv sawv kev muaj peev xwm. Qeeb qeeb -} tshuab fuse yuav muaj ib qho kev txiav txim siab muaj nuj nqis ntawm qhov ntau dua li kev ntaus nqi tib yam tam sim no.
5. Qhov kub thiab txias ua kom sov:Fuse cov kev ntsuas yog feem ntau muab ntawm 25 degree. Lawv txoj kev ncig ua si cov yam ntxwv hloov nrog qhov kub cua sov. Nyob rau hauv ib puag ncig kub (piv txwv li, sab hauv ib lub cim ntim), lub fuse yuav tawg ntawm qhov qis dua tam sim no dua li nws txoj kev ntaus nqi. Tham cov chaw tsim khoom siv cov kab nkhaus.
