Kev nqa khoom ntawm PCB nyob ntawm cov hauv qab no: LINE davth, kab tuab (tooj liab tuab), tso cai kub nce siab.

Raws li peb txhua tus paub, qhov dav ntawm PCB taug, qhov ntau dua cov peev xwm nqa tau tam sim no.

Piv txwv tias nyob rau hauv tib txoj kev mob, ib kab ntawm 10 lab yuav tiv taus 1A, cov neeg hlau loj npaum li cas? Puas yog 5A?

Cov lus teb, ntawm chav kawm, yog tsis muaj. Nyeem saib cov ntaub ntawv hauv qab no los ntawm cov thawj coj thoob ntiaj teb:

Chav tsev ntawm Kab Dav:Nti (1inch = 2.54cm = 25.4 hli)

Cov ntaub ntawv cov ntaub ntawv:MIL-STD-275 Luam Ntawv Xov Tooj Rau Cov Khoom Siv Hluav Taws Xob
