Ndeipi basa rinoitwa neSMD inductor mumarambi ekuchengetedza simba re LED?
Sezvo chip inductors ichigona kuwedzera hupenyu hwesevhisi yevazhinji zvigadzirwa zvemagetsi zvevatengi, kuvandudza mhando yezvigadzirwa, hunhu husina kujairika, uye kuita, zvakaiswa mukushandiswa nevazhinji vagadziri.
Haisi kungoiswa kumagetsi emagetsi emagetsi chete, asiwo maodhiyo emidziyo, zvigadziriso zvemagetsi, midziyo yemumba uye zvimwe zvigadzirwa zvemagetsi nemagetsi, kuitira kuti masaini emagetsi arege kukanganiswa, uye panguva imwe chete, haipindire masaini kana. electromagnetic radiation inoburitswa nemimwe michina yakatenderedza. .
Marambi ekuchengetedza magetsi anoshandiswa zvakanyanya muhupenyu hwedu; uye marambi ekuchengetedza simba e LED anonyanya kuumbwa ne semiconductor light-emitting diodes; iwo rudzi rwechiedza chinopedza simba shoma uye ine hupenyu hurefu hwebasa.
Iyo yemukati yedunhu re LED rekuchengetedza simba rambi isimba redunhu substrate, iro rinonyanya kusanganisira electrolytic capacitors, resistors, simba inductors, ceramic capacitors, etc. Pakati pavo, nhamba shoma ndeye chip power inductors, uye basa rayo rinonyanya kukosha. .
inonyanya kuvharira AC uye DC, uye kuvhara yakakwira frequency uye yakaderera frequency (sefa). Ehe, dunhu remagetsi rinonyanya kuvhara AC uye DC. Zvinogona kuoneka kuti kuramba kweiyo chip simba inductor kuDC kunenge zero.
Pasi pemamiriro azvino ayo dunhu rinobvumira kupfuura, iyo chip inductance inotadzisa kupfuura kweiyo AC point, inodzivirira bhodhi redunhu kubva pakukuvadzwa, uye inowedzera zvakanyanya hupenyu hwebasa re LED.
