Thermosetting SB578F / AU4V110X ikurikirana ya solenoid valve coil

Ntabwo twakwirengagiza inductance ya parasitike, coil induction, coil electromagnetic

1. Byamenyekanye ko inductance ya parasitike idashobora kwirengagizwa ni kimwe cya kabiri cyinduction ya parasitike igomba kwitabwaho muri PCB hakoreshejwe igenamigambi.

Mugutegura imiyoboro yihuta yihuta ya digitale, ibyangiritse biterwa no kwinjizwa kwa parasitike ya vias mubisanzwe biruta ibyatewe nubushobozi bwa parasitike.Inductance ya parasitike yayo izagabanya umusanzu wa bypass capacitor hamwe ningaruka zo kuyungurura sisitemu yose itanga amashanyarazi.

2. Turashobora gukoresha formula ikurikira kugirango tubare hafi ya parasitike inductance ya a binyuze:

L = 5.08h.Birashobora kugaragara kuri formulaire ko diameter yumurongo unyuze mu mwobo idafite uruhare runini kuri inductance, ariko uburebure bwurwobo buciye bugira uruhare runini kuri inductance.Ukoresheje urugero rwavuzwe haruguru, induction yumwobo irashobora kubarwa nka: l = 5.08 x 0.050 [muri (4x0.050 / 0.010) +1] = 1.015 NH.Niba igihe cyo kuzamuka kwikimenyetso ari 1nS, impedance ihwanye ni XL = TL / T10-90 = 3.190.Ubu bwoko bwa impedance ntibushobora kwirengagizwa mugihe hari imirongo myinshi yumurongo.Ni ngombwa cyane cyane kumenya ko capacitor ya bypass ikeneye kunyura muri vias ebyiri mugihe uhuza urwego rwingufu na stratum, bityo induction ya parasitike ya vias iziyongera cyane.

Impamvu zo gushyushya inductance

Menyekanisha kandi usobanure impamvu yo gushyushya inductance.

1. Umugozi ni muto cyane, uzatera kwihanganira inductor kuba nini cyane.Mugihe ibintu byerekana ko agaciro keza kagezweho ari ibisanzwe, nibisanzwe ko pole ishyuha.

2, inductance iruzuye, kandi ubu bwoko bwumuriro nabwo burakwiriye cyane.

3. Hariho imbaraga nini zo kunyeganyega ku mpande zombi za inductor, bityo intangiriro ihinduka kugirango ibe nini, ishobora kugabanya umubare wimpinduka no kugabanya uburebure bwumurongo.Guhindura imbere, guhindagurika gato, gutakaza imbaraga za magneti, cyane cyane ubushyuhe bwo guhangana.
