Chip inductors, inozivikanwawo semagetsi inductors, ndechimwe chezvinhu zvinowanzoshandiswa muzvigadzirwa zvemagetsi, zvine miniaturization, high quality, high energy storage uye kushomeka kwekudzivirira.Inowanzotengwa mumafekitari ePCBA.Paunosarudza chip inductor, maitiro ekushanda (akadai se inductance, rated current, quality factor, etc.) uye chimiro chechimiro chinofanira kufungwa.
I. Iyo chip inductor performance parameters
1. The inductance of the smooth characters: inductor nekuda kwekushanduka kwekushisa kwezvakatipoteredza 1 ℃ yakagadzirwa ne inductance yekudzokorora kwe △ L / △ t uye yepakutanga inductance L kukosha kana ichienzaniswa nekukosha kweinductor tembiricha system a1, a1 = △ L / L△ t.Mukuwedzera kune inductor tembiricha coefficient kuti uone kugadzikana kwake, asi zvakare iva nechokwadi chekuteerera kune inductance ye mechanical vibration uye kukwegura kunokonzerwa nekuchinja.
2. Kupokana kusimba remagetsi uye humidity kudzivirira kuita: Kune inductive zvishandiso zvine kuramba kusimba remagetsi zvinoda kusarudza kushandisa pasuru zvinhu kurwisa kuomarara kwevoltage yakakwira, kazhinji ndiyo yakanyanya kunaka voltage resistance inductive zvishandiso, kudzivirira hunyoro kuita kuri nani zvakare. .
3. Inductance uye kutsauka kunobvumidzwa: inductance inoreva zita rezita re inductance rinoonekwa ne frequency inodiwa neiyo chigadzirwa tekinoroji standard.Iyo unit of inductance ndiHenry, millihen, microhen, nanohen, kutsauka yakakamurwa kuva: F level (± 1%);G level (± 2%);H mwero (± 3%);J level (± 5%);K nhanho (± 10%);L level (± 15%);M mwero (± 20%);P level (± 25%);N nhanho (± 30%);inonyanya kushandiswa iJ, K, M level.
4. Kuongorora nguva yakawanda: kunyatsoonekwa kwehuwandu hweinductor L, Q, DCR values, inofanira kutanga yawedzera kushandura ikozvino kune inductor iri kuedzwa maererano nezvinodiwa, iyo inoswedera pedyo nehuwandu hwemazuva ano kune chaiyo yekushanda frequency yeinductor iyi. , zvakanyanya kunaka.Kana iyo inductor kukosha kweyuniti iri diki seyero nahum, kuwanda kwemidziyo inoyerwa kunoda kuongororwa kuti isvike 3G.
5. DC kuramba: Kuwedzera kune simba inductor midziyo haiedzi DC kuramba, imwe imwe inductor midziyo zvichienderana nekudikanwa kwekutsanangura iyo yakanyanya DC kuramba, kazhinji idiki ndiyo inonyanya kudiwa.
6. Kushanda kukuru ikozvino: kazhinji kutora 1.25 kusvika 1.5 nguva yakatarwa ikozvino yeinductor seyakanyanya kushanda ikozvino, kazhinji inofanira kuderedzwa ne50% kushandisa kuti ive yakachengeteka uye yakavimbika.
II.Iyo chip inductor fomu chinhu
Sarudza ma inductors emagetsi anotakurika maapplication, iwo matatu akanyanya kukosha mapoinzi ekufunga ndeaya: saizi, saizi saizi, yechitatu kana saizi saizi.
Iyo yedunhu bhodhi nzvimbo yenharembozha yakasimba kwazvo uye yakakosha, kunyanya sezvo akasiyana maficha akadai seMP3 vatambi, TV uye vhidhiyo zvinowedzerwa pafoni.Iko kuwedzera kushanda kuchawedzerawo kushandiswa kwemazuva ano kwebhatiri.Nekuda kweizvozvo, mamodule akambofambiswa nemagetsi emagetsi kana akabatana zvakananga kubhatiri anoda mamwe magadzirirwo anoshanda.Nhanho yekutanga yekuenda kune imwe mhinduro inoshanda ndeye kushandiswa kwemagineti buck converter.Sezvinoreva zita, inductor inodiwa panguva ino.
Mamiriro makuru eiyo inductor, kunze kwehukuru, inductance kukosha pakuchinja frequency, DC impedance (DCR) yecoil, yakatarwa saturation ikozvino, yakayerwa rms ikozvino, AC impedance (ESR), uye Q-factor.Zvichienderana nekushandiswa, kusarudzwa kwemhando ye inductor - yakadzivirirwa kana isina kuvharwa - inokoshawo.
Chip inductors inotaridzika zvakafanana pakuonekwa, uye hazvigoneke kuona mhando.Muchokwadi, iwe unogona kuyera inductance ye chip inductors ine multimeter, uye iyo general inductance yehurombo hwemhando yepamusoro chip inductors haizadzise zvinodiwa, uye kukanganisa kuchave kwakakura.
