Phapang lipakeng tsa inductor le inductor e tloaelehileng| U FOLE

Metsoalle e utloisisang li-inductors e tseba hore ho na le mefuta e 'meli ea li-inductors ka har'a sehlopha sa li-inductors: li-inductors tse sirelelitsoeng le li-inductors tse sa sireletsehang. Sehloohong se fetileng, re boetse re boletse mefuta ena e 'meli ea li-inductors, empa ha rea ​​ka ra e bapisa hammoho. Kajeno, baetsi ba inductor tla le uena ho utloisisa phapang pakeng tsa li-inductors tse sirelelitsoeng le li-inductors tse sa sireletsehang.

Phapang pakeng tsa li-inductors tse sirelelitsoeng le li-inductors tse sa sireletsehang

U nahana hore li-inductors tsohle tse potileng ke li-inductors tse sirelelitsoeng? Inductor e sirelelitsoeng ke inductor e pota-potiloeng ke mokokotlo oa makenete. Ha se li-inductors tsohle tse pota-potiloeng ke li-cores tse nang le li-inductors tse sirelelitsoeng, tse kang li-inductors tsa GNL, tseo le tsona li pota-potiloeng ke li-cores empa li sa sireletseha. Ke habohlokoa ho khetholla li-inductors tse sirelelitsoeng le tse sa sireletsehang ka ntle ho fumana hore na inductor e pota-potiloe ke motsoako oa magnetic. Sekhahla sa tlhaselo ea inductance

Ka kakaretso, terata e sa sireletsehang ea enameled e pepesoa ka ntle ntle le sekoaelo sa tšireletso ea makenete; Inductor e sireletsang e nang le tšireletso ea makenete, khanyetso e ntle ea EMI, e fokotsa tšitiso ea motlakase ea inductor ho ea lefats'eng le kantle, e fokotsa tšitiso ea lebala la motlakase le hlahisoang ke potoloho ho likarolo tse ling.

Ha e le hantle, ho na le phapang e kholo pakeng tsa inductance e sirelelitsoeng le inductance e sa sireletsehang ke hore inductance e sirelelitsoeng ke potoloho e koetsoeng ea makenete, athe inductance e sa sireletsehang ke potoloho e bulehileng ea makenete. Seo ho thoeng ke potoloho ea makenete e koetsoeng e bolela hore potoloho eohle ea makenete e koetsoeng e entsoe ka lisebelisoa tsa makenete, athe potoloho e bulehileng ea khoheli e bolela hore ho na le lekhalo le hlakileng la moea ho potoloho ea makenete. Sekhahla sa theko ea thepa ea Inductor Co

Ha li fapane feela, empa ho na le ho tšoana ho itseng. Bolumo ba bona ka kakaretso bo nyane, bokaholimo bo bonolo ho khomarela, bo loketse tlhahiso ea othomathiki, ho latela litlhoko tse fapaneng tsa bareki ho hlahisa litlhaloso tse fapaneng tsa boholo ba bareki ho khetha. Ha re bua ka mokhoa o leka-lekaneng, inductor e sa sirelelitsoeng e na le khanyetso e ntle ea welding le mocheso o hanyetsanang le mocheso, o loketseng bakeng sa ho tjheseletsa ka kakaretso le ho tjheseletsa reflow, ka theko e tlaase.

Inductor e kopantsoeng le phapang e tloaelehileng ea inductor

Ho nepahala ha inductor e kopaneng e phahame hanyane ho feta ea inductor e tloaelehileng. Ka kakaretso, li-inductors tse kopaneng li nepahetse ka 20% feela, athe li-inductors tse ling li nepahetse ka 10%. Le li-inductors tse ling li na le ho nepahala ho betere, joalo ka 5%, ha li bapisoa le 20% bakeng sa li-inductors tse kopaneng. Kaha ho nepahala ha inductor e kopantsoeng ho fokola, ke hobane'ng ha u nka karolo e kholoanyane ea 'maraka?

Lebaka ke hobane li-inductors tse kopantsoeng li na le melemo ho latela litekanyetso tsa inductance. E na le mefuta e mengata e patisaneng ea litekanyetso tsa ho utloa. Ka kakaretso, boleng ba eona ba inductance bo ka tlase ho 100uH, 'me mefuta e meng ea li-inductors e kopantsoeng e ka fihlela boleng ba inductance ka tlase ho 1uH. E qotsitse sekgahla sa ho tlanya

Rea tseba hore inductance e kopantsoeng le inductance e tloaelehileng ka kutloisiso ea lipalo, phapang pakeng tsa motlakase o kopantsoeng oa motlakase o moholoanyane, haeba kutloisiso ea bona ea palo e le 10 er, motlakase o kopantsoeng oa motlakase o ka etsa lintho tse ngata, karolelano ea hona joale ea inductor e nyenyane, kahoo ba bang. lihlahisoa tsa litlhoko tsa linomoro ha li phahame, empa tabeng ea hona joale e kholo, ho sebelisoa ha inductance e kopantsoeng ho feta, joalo ka k'homphieutha le masimo a mang.

Ena ke kenyelletso ea li-inductors, haeba u batla ho tseba haholoanyane ka li-patch inductors, ka kopo ikopanye le li-inductor.
