Kodi Kuwombera Kwa Smd Inductor | KHALANI BWINO

Tsatirani akatswiri tchipisi inductor kuti akuuzeni,Kodi smd inductor kumulowetsa ndi chiyani?

Kodi mukudziwa kapangidwe ka inductor?

Inductor nthawi zambiri amakhala ndi chimango, kumulowetsa, chikopa, zokutira, pakati kapena pachimake, etc.

Mafupa amtunduwu amatanthauza ma coil oyimitsira ena. Makina ena akuluakulu osinthika kapena osinthika (monga ma coil osokonekera, ma baffles, ndi zina zambiri) amalunga waya wopindika (kapena waya wa gauze) kuzungulira mafupa, kenako ndikuyika maginito kapena pachimake mkuwa, chitsulo pachimake, ndi zina zambiri, mkatikati mwa mafupa, kuti muwonjezere kuchuluka kwa inductance. Thandizo limapangidwa ndi pulasitiki, bakelite, ceramic ndi zinthu zina, ndipo zimatha kupangidwa mosiyanasiyana malinga Masensa ang'onoang'ono (monga masensa ojambulidwa ndi mitundu) nthawi zambiri sagwiritsa ntchito sensa, koma amakulunga waya wopindika molunjika mozungulira maginito. Inductor yopanda pake (yomwe imadziwikanso kuti koyilo yokhotakhota kapena koyilo, yomwe imagwiritsidwa ntchito kwambiri Maseketi -frequency) sagwiritsa ntchito maginito, mafupa ndi chishango, ndi zina zambiri. M'malo mwake, chovalacho chimavulazidwa nkhungu isanachotsedwe, ndipo mtunda pakati pa koyilo lililonse umakulitsidwa pang'ono.

2.winding kumulowetsa amatanthauza ya koyilo ndi ntchito mwachindunji, ndiye chigawo chachikulu cha inductor.The kumulowetsa anawagawa monolayer ndi multilayer.There pali mitundu iwiri ya single-wosanjikiza kumulowetsa: pafupi bala (kumulowetsa waya kutembenukira kumodzi) ndikusokonekera (kumulowetsa waya uliwonse ndikutalikirana kwina); Makulidwe amitundu yambiri ali ndi kutsetsereka mosakhazikika, kumulowetsa mwachisawawa, zisa zisa ndi zina zambiri.

3.Maginito pachimake ndi maginito bar maginito pachimake nthawi zambiri amatenga faifi-zinc ferrite (NX mndandanda) kapena manganese zinc ferrite (MX mndandanda) ndi zida zina, kuphatikiza mawonekedwe a I, mawonekedwe, kapu, mawonekedwe a E, mawonekedwe amphika, ndi zina zambiri.

Zipangizo 4.core pachimake makamaka pakachitsulo zitsulo pepala, permalloy, etc., mawonekedwe ake ndi "E" mtundu.

5.Pofuna kupewa maginito omwe amapangidwa ndi ma inductors omwe amakhudza magwiridwe antchito azinthu zina, zida zotetezera zitsulo (monga coil oscillation wa semiconductor radio, etc.) zimawonjezeredwa pachikuto chotetezera. amatetezedwa, kutayika kwa koyilo kumawonjezeka ndipo mtengo wa Q umachepa.

6.Zida zonyamula zimaphatikizira ena inductors (monga ma code inductors amtundu, inductors amtundu wa utoto, ndi zina). Atatha kumulowetsa, koyilo ndi pachimake zimasindikizidwa ndi zinthu zopakira.Zinthuzo zimapangidwa ndi pulasitiki kapena epoxy resin.

Kodi cholinga cha bala inductor ndi chiyani?

Ntchito: Chogulitsachi chimagwiritsidwa ntchito kwambiri modemu ya XDSL ndi ma TV a cable, makompyuta, makamera a digito ndi ma TV ena ang'onoang'ono, LCD TV, kamera, VRC yonyamula, ma audio yamagalimoto, mawailesi opyapyala, ma TV, mafoni opanda zingwe, ndi zina zambiri.

Kodi muyenera kumvetsera chiyani mukamayendetsa tchipisi?

Malinga ndi zosowa za dera, njira yokhotakhota ya tchipisi imasankhidwa.

Mukamapanga dzenje, ngati malinga ndi zofunikira za dera, kukula kwa m'mimba mwake ndi kukula kwa mafupa a coil a inductance, njira yokhotakhota, pakati pa koyilo wokulirapo ndioyenera kugwiritsidwa ntchito pafupipafupi komanso pafupipafupi, kuchuluka kwake kumakhala kochepa kuposa nthawi 3-5, koma palibe mafupa, amatha kukhala ndi katundu wabwino, mtengo wapamwamba wa Q, amatha kufikira 150-400, kukhazikika kumakhalanso kwakukulu.

Chosanjikiza chimodzi chomangirizidwa bwino chimakhala choyenera pamafupipafupi komanso mafunde apakatikati, mtengo wake wa Q umatha kufikira 150-250, ndipo umakhala wolimba.

Ntchito ya bala inductor ndi chiyani?

Ntchito yayikulu ya bala la inductor: kusefa, oscillation, kuchedwa, notch, ndi zina zambiri.

M'mayendedwe amagetsi, pazomwe zimachitika pakadali pano za AC, iyo ndi resistor kapena capacitor imatha kupanga fyuluta yayikulu kapena yotsika, gawo losunthira gawo ndi dera lokhala ndi resonant; Transformer imatha kulumikiza AC, voliyumu yamagetsi, kusintha kwamakono ndi kutembenuka kwa impedance.

Udindo wa bala chigamba inductor zikuwoneka ngati penapake, tanena kuti capacitor ndi kudzera ndi mwa kukana molunjika, ndipo inductor ndi zosiyana, udindo wake ndi kudzera ndi mwa kukana mwachindunji, malangizo a maginito kwaiye zowongolera mwachindunji kudzera mu inductor ndizofanana, sizisintha.

Pamwambapa ndikumvetsetsa koyenera kwa inductor, ndikuyembekeza kukhala ndi thandizo lina kwa inu.Ndife ogulitsa chip kuchokera ku China, tilandireni kuti mutifunsire!
