Best Transistors: BJTs
- 1 NPN – 2N3904. Koj tuaj yeem pom feem ntau NPN Transistors hauv qis-sab hloov circuits. …
- 2 PNP – 2N3906. Rau high-sab hloov circuits, koj xav tau PNP style BJT. …
- 3 Fais fab - TIP120. …
- 4 N-Channel (Logic Level) – FQP30N06L.
Koj xaiv lub transistor li cas rau kev hloov?
Nyob rau hauv xaiv qhov tsim nyog hloov transistor:
- Tus transistor qhov siab tshaj plaws cov khoom siv tam sim no yuav tsum siab tshaj qhov load tam sim no.
- Tus transistor qhov siab tshaj plaws tam sim no nce yuav tsum yog tsawg kawg 5 npaug ntawm qhov load tam sim no muab faib los ntawm qhov siab tshaj tawm tam sim no los ntawm IC.
Dab tsi yog qhov ceev tshaj plaws hloov transistor?
–IBM Corp. hnub no tshaj tawm txoj kev txhim kho tshiab silicon-germanium (SiGe) transistor, uas muaj peev xwm ncav cuag qhov nrawm ntawm 210 GHz thaum kos duab tsuas yog milliamp ntawm hluav taws xob tam sim no.. Raws li IBM, lub transistor yog lub ntiaj teb tus ceev tshaj plaws silicon-based ntaus ntawv tshaj tawm rau hnub tim.
Nyob hauv qhov xwm txheej twg transistor yuav ua haujlwm li hloov?
Nyob rau hauv ib qho kev hloov zoo tagnrho, lub transistor yuav tsum nyob hauv ib qho ntawm ob lub xeev: tawm lossis qhib. Lub transistor tawm thaum tsis muaj qhov tsis sib haum xeeb lossis thaum qhov kev tsis sib haum xeeb tsawg dua 0.7 V. Qhov hloov pauv yog nyob rau thaum lub hauv paus yog saturated kom cov khoom tam sim no tuaj yeem ntws yam tsis muaj kev txwv.
Qhov twg siv cov transistor feem ntau?
yog nyob deb ntawm cov transistor siv dav tshaj plaws rau ob qho tib si digital circuits thiab analog circuits, suav txog 99.9% ntawm tag nrho cov transistors hauv ntiaj teb. Lub bipolar hlws ris transistor (BJT) yav tas los yog qhov feem ntau siv transistor thaum xyoo 1950 txog 1960s.

Qhov twg yog qhov kev hloov pauv hloov kho kom muaj kev ntseeg siab rau kev ntseeg?
Tej zaum qhov kev yeej ua tiav tshaj plaws rau Kev Txhaum Cai Hloov Kho yog qhov kho dua ntawm Roman Catholic domination hauv Poland thiab hauv Hussite Bohemia. Thaum twg Catholic Counter-Reformation? Lub Rooj Sab Laj ntawm Trent yog pawg sab laj ecumenical ntawm lub Koom Txoos Roman Catholic uas tau sib tham los ntawm 1545 txog 1563.
Qhov twg yog qhov kev txiav txim siab rau kev tsis lees paub thiab rau kev ua kom muaj kev tawm tsam ntawm kev tawm tsam?
Kev qhuab ntuas tau siv los ntawm cov thawj coj loj hauv cov tub rog Romanrau txim rau cov koom haum lossis pab pawg loj ua txhaum cai, xws li kev ua phem, kev tawm tsam, kev tawm tsam, thiab kev tsis ncaj ncees, thiab rau lub pacification ntawm rebellious legions.
Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
Qhov kev tshwm sim hauv lub neej tseem ceeb ntawm kev ntsuas kev ntsuas kev sib raug zoo twg muaj tus lej ntau tshaj?
Qhov kev tshwm sim ntawm qib siab tshaj yog tuag ntawm tus txij nkawm(nrog tus nqi nruab nrab ntawm 100), txheeb ze rau kev sib yuav, nrog tus nqi nruab nrab ntawm 50, thiab, piv txwv, kev tuag ntawm tus phooj ywg ze, uas tau qhab nia 37. Qhov xwm txheej tseem ceeb ntawm lub neej ntawm Kev Hloov Kho Kev Ntsuas Kev Ntsuas Qhov Ntsuas puas muaj cov lej hloov pauv lub neej ntau tshaj?
