Uyini umehluko phakathi kobuhlalu bamagnetic ne-inductor | ULULAME

Umehluko phakathi kobuhlalu bamagnetic ne-inductor ukuthi i-inductor iyithuluzi lokugcina amandla, kuyilapho ubuhlalu bukazibuthe bungumshini wokuguqula amandla (ukusetshenziswa). esetshenziswa kakhulu kuma-circuits wesiginali, ikakhulukazi i-EMI.Ngaphansi, abakhiqizi be- chip inductorbazokhuluma ngomehluko phakathi kobuhlalu bamagnetic kanye nabangenisi.

I-chip inductor

Izingxenye ezifakwayo kanye nezinto zokuhlunga ze-EMI zisetshenziswa kakhulu kumjikelezo we-PCB wemishini ye-elekthronikhi.Izinto lezi zifaka i-chip inductors kanye ne-chip ubuhlalu bamagnetic. Izici zalawa madivayisi womabili zichazwe ngezansi futhi izinhlelo zazo ezijwayelekile kanye nezicelo ezikhethekile ziyahlaziywa.

Izinzuzo zokusebenzisa ama-chip inductors:

Izinzuzo zezinto ezingaphezulu kokuphakama ngosayizi wazo omncane wephakeji namandla abo okuhlangabezana nezidingo zesikhala sangempela.

Chip ubuhlalu kazibuthe

Umsebenzi oyinhloko wobuhlalu be-chip magnetic ukuqeda umsindo we-RF ekwakhiweni kolayini wokudlulisa (isifunda se-PCB) .Ubuhlalu be-sheet kazibuthe benziwe ngezinto ezithambile zikazibuthe ze-ferrite futhi zakha isakhiwo se-monolithic esinokuphakama kwevolumu ephezulu. Ukulahleka kwamanje eddy kulingana nesikwele semvamisa yesiginali.

Izinzuzo zokusebenzisa ubuhlalu be-chip magnetic:

I-miniaturization nokukhanya.I-impedance ephezulu ebangeni lemvamisa yomsindo we-RF isusa ukuphazanyiswa kwamandla kagesi emigqeni yokudlulisela.Isakhiwo sesekethe kazibuthe, ukuqeda kangcono isignali crosstalk.Excellent magnetic shielding structure.Redual the DC resistance to avoid attenuation over of the useful signal.

Izizathu zokusebenzisa ubuhlalu be-chip kanye ne-chip inductors:

Ukuthi usebenzise ubuhlalu be-chip noma i-chip inductors kuncike kakhulu kuhlelo lokusebenza.Izinsimbi ze -hip ziyadingeka kumasekethe anezikhala.Uma udinga ukuqeda umsindo we-EMI ongadingeki, ukusebenzisa i-chip magnetic bead kuyisinqumo esingcono kakhulu.

Okuqukethwe okungenhla kuhlelwe futhi kwanyatheliswa abahlinzeki be-chip inductor.Uma ungazi ukuthi wenzeni, sicela useshe i- " Inductorchina.com ".
