Imashanyarazi ya SMT
Ibyiza:
1. Gutwara imashini itwara imashini ikoreshwa kuri SMT
2. Umuyoboro mwinshi cyane, DCR yo hasi.
3. Bikwiranye no kugurisha SMT Ubukorikori.
4. Kubaka kubahiriza RoHS no kuyobora kubuntu
5. Kwuzura kwinshi ibintu byingenzi nubunini buto
6. Imiyoboro yuzuye igera kuri 14 A.
7.CD31 / CD32 / CD42 / CD43 / CD52 / CD53 / CD54 / CD73 / CD75 / CD105 / CD105 irahari kugirango uhitemo.
8. Ipaki: Gupakira Tape & Reel.
Ingano n'ibipimo:
| A | B | C | D |
| 9.0 ± 0.3 | 6.4 ± 0.3 | Φ10.0 ± 0.3 | 3.0 ± 0.3 |
Ibikoresho by'amashanyarazi:
| INGINGO | SPEC. | TOLERANCE | TESI KUBUNTU | IBIKORESHO BY'IKIZAMINI |
| INDUCTANCE | 3.0mH | ± 10% | 100kHz / 0.25V | HP-4284A |
| DCR | 7.2Ω | Icyiza. | kuri 25 ° C. | CH-502A |
| IDC | 0.32A | L0A * 90% Mim. | 10kHz / 0.25V | CD106S + CD1320 |
Porogaramu:
1. Guhindura ibiyobora hamwe na voltage ikora (amakarita ashushanyije, yashyizwemo PC-Ikarita, imbaho nyamukuru)
2.Ihindura DC / DC ihindura
3.Kumurika LED, ibikoresho byitumanaho bigendanwa,
4. Gukurikirana, Kamera igendanwa, Itumanaho, ibicuruzwa bya digitale
Nigute ushobora guhitamo inductor ibereye yo gutunganya chip ya SMT?
1. Ubugari bwuzuye bwa chip inductor igomba kuba munsi yubugari bwuzuye bwa inductor kugirango wirinde ibikoresho byo kugurisha birenze urugero bitera guhangayika bikabije kugirango uhindure agaciro ka inductor mugihe amazi akonje.
2. Ubusobanuro bwibikoresho bya chip biboneka ku isoko ryo kugurisha ahanini ± 10%.Niba ibisobanuro birenze ± 5%, ugomba gutumiza hakiri kare.
3. Induction zimwe za chip zirashobora gusudwa nitanura ryerekana no kugurisha imiraba, ariko hariho na inductor zimwe na zimwe zidashobora gusudira no kugurisha imiraba.
4. Iyo ivugurura, ntibishoboka gusimbuza inductor hamwe na chip inductor gusa kubwinshi bwa inductor.Kugirango tumenye ibiranga imikorere, birakenewe kandi gusobanukirwa urwego rwimikorere ya chip inductors.
5. Igishushanyo mbonera nigisobanuro cyibanze cya chip inductors birasa, kandi igishushanyo mbonera ntigifite ikimenyetso gikomeye.Mugihe kugurisha intoki cyangwa intoki zakozwe n'intoki, ugomba kwitonda cyane kandi ntukore amakosa cyangwa ngo utore ibice bitari byo.
6. Kuri iki cyiciro, hari indimu eshatu zisanzwe: ubwoko bwa mbere, inductors nyinshi cyane zo gushyushya microwave.Irakoreshwa kumurongo wa porogaramu hafi ya 1GHz.Ubwoko bwa kabiri ni chip-inductors nyinshi.Irakwiranye na seriveri ya resonance igenzura umuzenguruko hamwe ninshuro zitoranya amashanyarazi.Ubwoko bwa gatatu ni inductors zifatika.Mubisanzwe bikurikizwa kumashanyarazi ya megahertz mirongo.
7. Ibicuruzwa bitandukanye bikoresha ibipimo bitandukanye bya magnetiki.Nubwo ingano ya inductor ikoreshwa, igipimo cyo kurwanya cyerekanwe ntabwo ari kimwe.Mumurongo mwinshi wo kugenzura, gupima kurwanya ni bibi cyane kuri Q agaciro, bityo rero witondere mugihe utegura gahunda.
8. Biremewe kuba indangagaciro yagaciro ya chip inductance ukurikije umubare munini wubu.Iyo amashanyarazi atangwa agomba kuba ashinzwe ubwinshi bwumuyaga, iyi ndangagaciro agaciro ka capacitor igomba kwitabwaho.
9. Iyo amashanyarazi akoreshwa mumashanyarazi ya DC / DC, ingano yindimu zabo ihita ibangamira imyifatire yakazi yumuzunguruko.Ukurikije uko ibintu bimeze, uburyo bwo guhindura imashini ya magnetique burashobora gukoreshwa muguhindura inductors kugirango tugere kubisubizo bifatika.
10. Inductors-ibikomere bikunze kugaragara mubikoresho byitumanaho bikorera mumurongo wa 150 ~ 900MHz.Mumurongo wumurongo wumurongo wa 1GHz, microwave ishyushya inductor nyinshi igomba gukoreshwa.Iyo umukiriya akoresheje ubwoko bwa smt patch, birumvikana ko nayo iteganijwe mubice bitandukanye.Gusa ishyaka ritunganya rishobora kwemeza ko ryinjijwe mumasoko yo kugurisha nyuma yo gusuzuma amabwiriza yuzuye yumukiriya.
