Li-inductors tsa chip, tse tsejoang hape e le li-inductors tsa matla, ke e 'ngoe ea likarolo tse sebelisoang ka ho fetesisa lihlahisoa tsa elektronike, tse nang le miniaturization, boleng bo phahameng, polokelo e phahameng ea matla le khanyetso e tlase.E atisa ho rekoa ka lifeme tsa PCBA.Ha u khetha chip inductor, litekanyetso tsa ts'ebetso (tse kang inductance, rated current, quality factor, joalo-joalo) le sebopeho sa sebopeho se lokela ho nkoa.
I. Mekhahlelo ea ts'ebetso ea chip inductor
1. Inductance ea litšobotsi tse boreleli: inductor ka lebaka la mocheso oa tikoloho liphetoho 1 ℃ e entsoeng ke inductance ea tokiso ea △ L / △ t le boleng ba pele ba inductance L bapisoa le boleng ba tsamaiso ea mocheso oa inductor a1, a1 = △ L / L△ t.Ho phaella ho inductor mocheso coefficient ho fumana botsitso ba hae, empa hape ba bonnete ba hore ho ela hloko inductance ea thothometsa mechine le botsofali bakoang ke phetoho.
2. Ho hanyetsa matla a motlakase le ts'ebetso ea thibelo ea mongobo: Bakeng sa lisebelisoa tse kenyang matla tse hanyetsanang le matla a motlakase li hloka ho khetha ho sebelisa thepa ea sephutheloana ho hanela boima ba motlakase o phahameng, hangata lisebelisoa tse loketseng tsa ho hanyetsa motlakase, ts'ebetso ea ho thibela mongobo le eona e betere. .
3. Inductance le ho kheloha ho lumelletsoeng: inductance e bua ka data ea lebitso la inductance e bonoang ka makhetlo a hlokoang ke maemo a theknoloji ea sehlahisoa.Sehlopha sa inductance ke Henry, millihen, microhen, nanohen, ho kheloha ho arotsoe ka: F level (± 1%);Boemo ba G (± 2%);Boemo ba H (± 3%);Boemo ba J (± 5%);Boemo ba K (± 10%);Boemo ba L (± 15%);M boemo (± 20%);Boemo ba P (± 25%);Boemo ba N (± 30%);e sebelisoang haholo ke J, K, M level.
4. Maqhubu a ho lemoha: ho lemoha ka nepo palo ea litekanyetso tsa inductor L, Q, DCR, e tlameha ho qala ka ho eketsa motlakase o mong ho inductor e ntseng e lekoa ho ea ka litokisetso, ho atamela haufi le nako ea hona joale ho ea ho nako ea sebele ea ho sebetsa ea inductor ena. , e loketseng haholoanyane.Haeba yuniti ea boleng ba inductor e le nyane joalo ka boemo ba nahum, khafetsa ea lisebelisoa tse lokelang ho lekanyetsoa e hloka ho hlahlojoa ho fihlela 3G.
5. DC ho hanyetsa: Ho phaella ho lisebelisoa tsa motlakase oa motlakase ha li leke ho hanyetsa ha DC, lisebelisoa tse ling tsa inductor ho ea ka tlhokahalo ea ho hlakisa boholo ba khanyetso ea DC, hangata e nyenyane ho feta e lakatsehang.
6. Mosebetsi o moholo oa hona joale: hangata o nka 1.25 ho makhetlo a 1.5 ho feta tekanyo ea hona joale ea inductor e le palo e phahameng ea ho sebetsa hona joale, ka kakaretso e tlameha ho fokotsoa ke 50% ho sebelisa ho sireletseha le ho tšepahala haholoanyane.
II.The chip inductor form factor
Khetha li-inductors bakeng sa lits'ebetso tsa motlakase tse nkehang, lintlha tse tharo tsa bohlokoa tseo u ka li nahanang ke: boholo ba boholo, boholo ba boholo, boholo ba boraro kapa boholo.
Sebaka sa boto ea potoloho ea liselefouno se thata haholo ebile se bohlokoa, haholo-holo kaha likarolo tse sa tšoaneng tse kang libapali tsa MP3, TV le video li kenngoa fonong.Ts'ebetso e ntseng e eketseha e tla eketsa ts'ebeliso ea hona joale ea betri.Ka lebaka leo, li-module tseo pele li neng li tsamaisoa ke li-linear regulators kapa tse hokahaneng ka ho toba le betri li hloka tharollo e sebetsang haholoanyane.Mohato oa pele o lebisang ho tharollo e sebetsang haholoanyane ke ho sebelisa mochine oa magnetic buck.Joalo ka ha lebitso le bolela, ho hlokahala inductor ntlheng ena.
Litlhaloso tse ka sehloohong tsa inductor, ntle le boholo, ke boleng ba inductance ha u fetola frequency, DC impedance (DCR) ea coil, rated saturation current, rated rms current, AC impedance (ESR), le Q-factor.Ho itšetlehile ka kopo, khetho ea mofuta oa inductor - e sirelelitsoeng kapa e sa sireletsehang - e bohlokoa hape.
Li-inductors tsa chip li shebahala li tšoana ka ponahalo, 'me ha ho khonehe ho bona boleng.Ha e le hantle, o ka lekanya inductance ea li-inductors tsa chip ka multimeter, 'me ho kenngoa ka kakaretso ha li-inductors tsa boleng bo tlaase ho ke ke ha finyella litlhoko,' me phoso e tla ba kholoanyane.
