Thermosetting SB578F/AU4V110X moʻo alakaʻi solenoid valve coil

ʻAʻole e haʻalele ʻia ka inductance parasitic, inductance coil, electromagnetic coil

1. Ua hoʻolauna ʻia ʻo ka inductance parasitic hiki ʻole ke mālama ʻia ʻo ia ka hapalua o ka inductance parasitic pono e noʻonoʻo ʻia ma PCB ma o ka hoʻolālā ʻana.

I ka hoʻolālā ʻana i nā kaapuni kikohoʻe kiʻekiʻe, ʻoi aku ka nui o ka pōʻino i hana ʻia e ka inductance parasitic o vias ma mua o ka mea i hana ʻia e ka capacitance parasitic. E hoʻonāwaliwali kāna inductance inductance i ka hāʻawi ʻana o ka capacitor bypass a me ka hopena kānana o ka ʻōnaehana lako mana holoʻokoʻa.

2. Hiki iā mākou ke hoʻohana i kēia ʻano kumu no ka helu ʻana i ka inductance parasitic kokoke o kahi ma:

L=5.08h[In(4h/d)+1] kahi l e pili ana i ka inductance o ka via, h ka loa o ka via, a o d ke anawaena o ka puka waena. Hiki ke ʻike ʻia ma ke ʻano ʻano he liʻiliʻi ka hopena o ke anawaena o ka puka ma ka inductance, akā ʻo ka lōʻihi o ka puka ma ka hopena nui loa i ka inductance. Me ka hoʻohana ʻana i ka laʻana i luna, hiki ke helu ʻia ka inductance o ka puka: l = 5.08 x 0.050 [in (4x0.050/0.010)+1] = 1.015 NH. Inā ʻo 1nS ka manawa piʻi o ka hōʻailona, ​​ʻo ka impedance like ʻo XL=TL/T10-90=3.190. ʻAʻole hiki ke mālama ʻia kēia ʻano impedance inā loaʻa ke alapine kiʻekiʻe. He mea nui ia e hoʻomaopopo pono e hele ka capacitor bypass i ʻelua vias i ka wā e hoʻopili ai i ka papa mana a me ka stratum, no laila e piʻi nui ka inductance parasitic o nā vias.

Nā kumu o ka wela inductance

E hoʻolauna a wehewehe i ke kumu o ka hoʻomehana inductance.

1. He lahilahi loa ka uwea, e nui loa ai ke ku e o ka inductor. Ma lalo o ke kūlana i maopopo ka waiwai kūpono o ke au, he mea maʻamau ka wela o ka pou.

2, ua piha ka inductance, a ua laha loa keia ano kuni.

3. Loaʻa ka uila vibration nui ma nā ʻaoʻao ʻelua o ka inductor, no laila ua hoʻololi ʻia ke kumu i ʻoi aku ka nui, hiki ke hoʻemi i ka helu o nā huli a hoʻopōkole i ka lōʻihi o ka laina. Huli i mua, liʻiliʻi liʻiliʻi liʻiliʻi, liʻiliʻi liʻiliʻi hoʻoheheʻe magnetic, ʻoi aku ka nui o ka wela.
