Litšobotsi tsa thepa ea li-inductors tsa matla a terata le phapang pakeng tsa li-inductors tsa chip le li-inductors tsa maqeba a terata | U FOLE

Pele ho tsohle, ke inductor ea maqeba a terata ke eng?

Ho na le mefuta e mengata ea li-inductors, tse kang: li-inductors tsa matla, li-inductors tsa laminated, li-inductors tsa terata, joalo-joalo Kajeno, Gewei smd power chip inductors e tla u bolella ka li-inductors tsa maqeba a terata.

Inductor ea maqeba a mohala ke e 'ngoe ea li-inductors tsa chip. Ke leqeba la motsoako oa motlakase le nang le mehala e kentsoeng, hape ke e 'ngoe ea likarolo tse sebelisoang hangata lipotolohong. E sebelisoa haholo ho micro TV, LCD TV, kh'amera ea video, VRC e nkehang, molumo oa koloi, seea-le-moea se tšesaane, sesebelisoa sa TV, mohala oa thekeng, jj.

Li-inductors tsa Wirewound li na le melemo e mengata:

1. Ponahalo le boholo li lumellana le litekanyetso tsa EIA (Electronic Industry Association), 'me ho na le mefuta e mengata ea liphutheloana, tse ka sebelisoang ho liboto tsa potoloho tse nang le litlhoko tse fapaneng.

2. Karolo e holim'a thaba, kahoo e na le solderability e ntle, 'me e ka fana ka liphutheloana tsa theipi bakeng sa kopano e ikemetseng.

3. Ho hanyetsa mocheso.

4. Phallo e tlase ea matla a khoheli, ho hanyetsa ha DC, le khanyetso e phahameng ea hona joale.

5. Ho nepahala ho phahameng le tahlehelo e tlaase (ke hore, boleng bo boholo ba Q).

6. Mokhoa oa tlhahiso o bonolo 'me litšenyehelo li tlaase.

Mosebetsi oa mantlha oa winding inductance:

Ho sefa, oscillation, ho lieha, notch, joalo-joalo, beha feela: "feta DC, thibela AC".

Sebopeho sa winding inductance:

The winding inductance e na le skeleton, matsoelintsoeke, mokokotlo oa makenete, molamu oa makenete, le mokokotlo oa tšepe.

Thepa ea mantlha ea matla a khoheli ea motlakase oa terata leqeba matla inductor ha e tsitsa. Mokotla oa makenete o na le phallo ea makenete. Lisebelisoa tse fapaneng tsa mantlha tsa makenete, phallo ea makenete e fapane ka tlhaho, e qetellang e ama inductance ea leqeba la terata. Ha matla a khoheli a kenella ka matla ho matla a khoheli, ho tla ba le ho hola ha leqeba la terata! Lisebelisoa tse fapaneng tsa mantlha li boetse li hlahisa li-inductances tse fapaneng tsa maqeba a terata. Mohlala, inductance ea China Gewei Electronics e na le ferrite ea leqeba la terata. Li-inductors, li-inductors tsa terata tsa leqeba la li-ceramic, joalo-joalo Ho na le lisebelisoa tse peli tsa mantlha ho inductor ea leqeba la terata, 'me lisebelisoa tsena tse peli li boetse li ama ts'ebetso ea motheo ea leqeba la terata, ke hore, mokokotlo oa khoheli le terata. Xiaobian Jin Haode ha e bue ka terata, haholo-holo hore motho e mong le e mong a sekaseke tšusumetso ea matla a khoheli ho inductor ea leqeba.

SMD power chip inductor

Phapang pakeng tsa li-inductors tsa SMD laminated le li-inductors tsa leqeba la terata li bonts'oa haholo-holo ka likarolo tse 5: Phapang ea ts'ebetso ea tlhahiso: Li-inductors tsa terata tsa leqeba li ipapisitse le mokhoa oa setso oa tlhahiso ea leqeba la terata, o fetolelang li-inductors tsa setso hore e be sephutheloana sa SMD, ka nako e ts'oanang Molumo oa inductor o fokotsehile, 'me ho kenya le ho sebelisoa ho bonolo haholoanyane; the chip laminated inductor e entsoe ka ho sebelisa thekenoloji ea khatiso ea li-multi-layer le mokhoa oa tlhahiso ea laminated.

Phapang tse ling: The mocheso dissipation ea SMD laminated inductor molemo ho feta ea terata leqeba SMD inductor. phapang. Ho akaretsa, li-inductors tsa laminated tsa SMD ha li khone ho bona terata, 'me matla a ho kena-kenana le li-anti-inductance, ho senya mocheso, le ho boloka sebaka sa ho kenya li molemo ho feta li-inductors tsa maqeba a SMD , empa li-inductors tsa maqeba a terata li molemo ho latela khanyetso ea hona joale. litšenyehelo tsa tlhahiso ea inductance. Ho molemo hanyenyane, 'me boleng ba ESR ba ho kenya leqeba la terata bo phahame ho feta ba chip laminated inductance.

Pejana re boletse hore lisebelisoa tse fapaneng tsa mantlha tsa makenete li lebisa ka kotloloho ho inductance e fapaneng ea li-winding inductance. Ha e le hantle, ho phaella ho sena, mokokotlo oa makenete o boetse o etsa hore tšebeliso ea matsoelintsoeke e fapaneng e fapane! Li-magnetic cores tse fapaneng li na le ts'ebetso e fapaneng, le likarolo tse ling. Mohlala, li-inductors tsa leqeba la ferrite li loketse ho sebelisoa joalo ka li-inductors tsa motlakase, li-coil tsa choke, le li-inductors tsa polokelo ea matla. The winding inductance ea iron powder core material e na le litšobotsi tse matla tsa M, 'me e loketse ho sebelisoa e le sefe ho fokotsa tšitiso ea motlakase. Ho boetse ho na le li-inductors tsa chip tsa ceramic tse sebelisoang haholo ho arola mats'oao a AC, sefa kapa ho theha li-circuits tse nang le li-capacitor le li-resistors!
