Makhalidwe azinthu zama inductors amagetsi ndi kusiyana pakati pa ma inductors a chip ndi ma inductors a bala | KHALANI BWINO

Choyamba, kodi chowotchera mabala a waya ndi chiyani?

Pali mitundu yambiri ya inductors, monga: inductors mphamvu, laminated inductors, waya mabala inductors, etc. Lero, Gewei smd mphamvu chip inductors adzakuuzani za waya bala inductors.

Waya chilonda inductor ndi chimodzi mwa chip inductors. Ndi chilonda cha electromagnetic induction chigawo chokhala ndi mawaya otsekeredwa, komanso ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pamabwalo. Amagwiritsidwa ntchito kwambiri mu yaying'ono TV, LCD TV, kanema kamera, kunyamula VRC, zomvetsera galimoto, wailesi woonda, TV chochunira, foni yam'manja, etc.

Ma Wirewound inductors ali ndi zabwino zambiri:

1. Maonekedwe ndi kukula kwake zimagwirizana ndi EIA (Electronic Industry Association) miyezo, ndipo pali mitundu yambiri ya phukusi, yomwe ingagwiritsidwe ntchito pa matabwa ozungulira ndi zofunikira zosiyanasiyana.

2. Pamwamba phiri phiri mbali, kotero ali solderability wabwino, ndipo akhoza kupereka tepi ma CD kuti msonkhano basi.

3. Kukana kutentha.

4. Kutsika kwa maginito otsika, kutsika kwa DC, ndi kukana kwakukulu kwamakono.

5. Kulondola kwakukulu ndi kutayika kochepa (ndiko, mtengo waukulu wa Q).

6. Njira yopanga ndi yosavuta ndipo mtengo wake ndi wotsika.

Ntchito yayikulu ya winding inductance:

Kusefa, oscillation, kuchedwa, notch, etc., ingoikani: "pass DC, block AC".

Kapangidwe ka ma winding inductance:

Mapiritsi a inductance amakhala ndi chigoba, chopindika, maginito, ndodo ya maginito, ndi chitsulo pakati.

The maginito pachimake zakuthupi wa waya bala mphamvu inductor si okhazikika. Magnetic pachimake ali ndi maginito flux. Mitundu yosiyanasiyana ya maginito, maginito flux ndi yosiyana mwachilengedwe, yomwe imakhudzanso inductance ya chilonda cha waya. Kukwera kwamphamvu kwa maginito kwa maginito pachimake, kumapangitsanso kuti chiwongolero cha mabala a waya! Zida zosiyanasiyana zapakati zimapanganso ma inductances amabala a waya. Mwachitsanzo, inductance yathu ya China Gewei Electronics ili ndi waya bala chip ferrite. Ma inductors, waya chilonda Chip ceramic inductors, etc. Pali zida ziwiri pachimake pa waya bala inductor, ndipo zipangizo ziwirizi zimakhudzanso ntchito yaikulu ya waya chilonda inductor, ndiko kuti, maginito pachimake ndi waya. Xiaobian Jin Haode salankhula za waya, makamaka kuti aliyense afufuze momwe mphamvu ya maginito imagwirira ntchito pachilonda cha chilonda.

SMD power chip inductor

Kusiyanitsa pakati pa ma inductors a SMD laminated ndi ma inductors a mawaya kumawonekera makamaka muzinthu 5: Kusiyana pakupanga: Ma waya opangira ma chip inductors amatengera njira yachikhalidwe yopangira mabala a waya, yomwe imasintha ma inductors a plug-in kukhala ma SMD, komanso nthawi yomweyo Voliyumu ya inductor imachepetsedwa, ndipo kuyika ndi kugwiritsa ntchito ndikosavuta; Chip laminated inductor imapangidwa pogwiritsa ntchito makina osindikizira amitundu yambiri komanso njira yopangira laminated.

Kusiyanasiyana kwina: Kutentha kwa kutentha kwa SMD laminated inductor ndikwabwino kuposa kwa waya chilonda SMD inductor. kusiyana kwake. Mwachidule, ma inductors a SMD a laminated sangathe kuwona waya, ndipo mphamvu yoletsa kusokoneza, kutayika kwa kutentha, ndi kupulumutsa malo oyika ndikwabwino kuposa ma inductors a mawaya a SMD , koma ma inductors amabala amawaya ali bwino potengera kukana kwapano komanso mtengo wopangira inductance. Ndibwinoko pang'ono, ndipo mtengo wa ESR wa inductance yamabala a waya ndi wapamwamba kuposa wa chip laminated inductance.

M'mbuyomu tidanenanso kuti zida zosiyanasiyana zamaginito zimatsogolera ku inductance yosiyana ya ma inductance. M'malo mwake, kuwonjezera pa izi, phata la maginito limapangitsanso kugwiritsa ntchito ma inductance kukhala osiyana! Mitundu yosiyanasiyana ya maginito imakhala ndi machitidwe osiyanasiyana, ndi zina. Mwachitsanzo, ma inductors a chilonda cha chip ferrite ndi oyenera kugwiritsidwa ntchito ngati ma inductors amphamvu, ma coil otsamwitsa, ndi ma inductors osungira mphamvu. The mapindikidwe inductance wa chitsulo ufa pachimake chuma ali ndi mphamvu M makhalidwe, ndipo ndi oyenera kugwiritsidwa ntchito ngati fyuluta kuchepetsa kusokonezedwa electromagnetic. Palinso ma inductors a chip ceramic inductors omwe amagwiritsidwa ntchito kwambiri kupatula ma siginecha a AC, zosefera kapena kupanga ma resonant mabwalo okhala ndi ma capacitor ndi resistors!
