SMT Power Inductor
Ubwino:
1. Kugwiritsa ntchito tepi yonyamula katundu pa SMT
2. Odziwika kwambiri panopa, Low DCR.
3. Yoyenera reflow SMT Craft soldering.
4. Pangani kutsata kwa RoHS ndikuwongolera kwaulere
5. High machulukitsidwe pachimake zakuthupi ndi yaing'ono kukula
6. Machulukidwe mafunde mpaka 14 A
7.CD31/CD32/CD42/CD43/CD52/CD53/CD54/CD73/CD75/CD105/CD105 ilipo kuti musankhe.
8. Phukusi: Kuyika kwa tepi & Reel.
Kukula ndi makulidwe:
| A | B | C | D |
| 9.0±0.3 | 6.4±0.3 | Φ10.0±0.3 | 3.0±0.3 |
Mphamvu zamagetsi:
| ITEM | Chithunzi cha SPEC | KULERERA | TESI FREQUENCY | ZINTHU ZOYESA |
| INDUSTANCE | 3.0mH | ±10% | 100kHz / 0.25V | HP-4284A |
| Mtengo wa DCR | 7.2 Ω | Max. | pa 25°C | CH-502A |
| IDC | 0.32A | L0A*90% Mim. | 10kHz / 0.25V | CD106S+CD1320 |
Mapulogalamu:
1. Kusintha zowongolera zokhala ndi ma voltages otsika (makadi ojambula, Makhadi a PC ophatikizidwa, ma boardboard)
2.Integrated DC/DC converter
3.Kuwala kwa LED, Zida zoyankhulirana zam'manja,
4. Monitor, Kamera yonyamula, Kuyankhulana, zinthu za digito
Momwe mungasankhire chowongolera cha chip choyenera cha SMT chip processing?
1. Kuchuluka kwa chip inductor kuyenera kukhala kotsika kusiyana ndi kukula kwa inductor kuti apewe zinthu zowonongeka kwambiri kuti zisamapangitse kupanikizika kwambiri kuti zisinthe mtengo wa inductor pamene madzi atakhazikika.
2. Kulondola kwa ma chip inductors omwe amapezeka pamsika wogulitsa ndi ± 10%. Ngati kulondola kuli pamwamba kuposa ± 5%, muyenera kuyitanitsa msanga.
3. Ma chip inductors ena amatha kuwotcherera ndi ng'anjo ya reflow ndi soldering yoweyula, koma palinso ma inductors ena omwe sangathe kuwotcherera ndi ma wave soldering.
4. Pamene mukuwongolera, sizingatheke kuti m'malo mwa inductor ndi chip inductor ndi kuchuluka kwa inductor. Kuti mutsimikizire mawonekedwe ogwiritsira ntchito, ndikofunikira kumvetsetsa kuchuluka kwa ma frequency ogwiritsira ntchito ma chip inductors.
5. Mawonekedwe a maonekedwe ndi maziko a chip inductors ndi ofanana, ndipo mawonekedwe a mawonekedwe alibe chizindikiro chofunika kwambiri. Pamene mukugulitsa pamanja kapena mapepala opangidwa ndi manja, muyenera kusamala kwambiri ndipo musalakwitse kapena kunyamula mbali zolakwika.
6. Pakadali pano, pali ma inductors atatu odziwika bwino: mtundu woyamba, ma inductors apamwamba kwambiri otenthetsera ma microwave. Imagwira ntchito pama frequency osiyanasiyana kuzungulira 1GHz. Mtundu wachiwiri ndi high-frequency chip inductors. Ndi oyenera mndandanda resonance ulamuliro dera ndi pafupipafupi kusankha magetsi magetsi. Mtundu wachitatu ndi ma inductors othandiza. Nthawi zambiri amagwiritsidwa ntchito pamagawo amagetsi amakumi a megahertz.
7. Zogulitsa zosiyanasiyana zimagwiritsa ntchito ma diameter osiyanasiyana a maginito coils. Ngakhale muyeso womwewo wa inductor ukugwiritsidwa ntchito, muyeso wotsutsa womwe ukuwonetsedwa siwofanana. Muzowongolera pafupipafupi kwambiri, kuyeza kukana kumakhala kovulaza kwambiri pamtengo wa Q, chifukwa chake tcherani khutu popanga chiwembucho.
8. Zimaloledwa kukhala index index ya chip inductance malinga ndi kuchuluka kwakukulu kwapano. Pamene dera loperekera mphamvu liyenera kukhala ndi udindo pa kuchuluka kwazomwe zikuchitika, chiwerengero ichi cha capacitor chiyenera kuganiziridwa.
9. Pamene ma inductors amagetsi amagwiritsidwa ntchito mu otembenuza a DC / DC, kukula kwa inductors awo nthawi yomweyo kumawononga maganizo ogwirira ntchito a dera lamagetsi. Malinga ndi momwe zinthu zilili, njira yosinthira maginito coil nthawi zambiri ingagwiritsidwe ntchito kusintha ma inductors kuti akwaniritse zotsatira zabwino.
10. Ma inductors a mawaya ndi ofala pazida zoyankhulirana zomwe zimagwira ntchito pafupipafupi 150 ~ 900MHz. Mu ma frequency magetsi ozungulira 1GHz, ma inductors otenthetsera ma microwave ayenera kugwiritsidwa ntchito. Wogula akagwiritsa ntchito mtundu wa smt patch, inde, imafotokozedwanso mbali zosiyanasiyana. Chipani chokonzekera chokha chingatsimikizire kuti chikuphatikizidwadi mumsika wogulitsa pambuyo poganizira malamulo athunthu a kasitomala.
