Momwe mungakulitsire alumali moyo wa chip inductors?

Ponena za moyo wa alumali wa chip inductors, ndikukhulupirira kuti aliyense amadziwa, nthawi zambiri miyezi 6, malingana ndi njira yopangira ndi malo osungira.
Pankhani ya moyo wautumiki, choyamba tiyenera kuyamba ndi makhalidwe a maginito zipangizo. Nthawi zambiri, zinthu za ferrite zimaponyedwa pa kutentha kwambiri kuposa madigiri 1,000.
Choncho, ili ndi mphamvu zapamwamba ndipo ikhoza kutsimikiziridwa kwamuyaya. Ndiye ndi enameled mkuwa waya. Nthawi zambiri, posankha inductor, idzakhazikitsidwa pa inductance.
Kukaniza kwa DC DCR ndi IDC yaposachedwa ya DC kumawunikidwa. Pakali pano nthawi zambiri amakhala ndi theka. Zoonadi, kukana kochepa, kumakhala bwino.
Ngati magawo onse akwaniritsidwa, koyiloyo idzagwira ntchito mosavuta. Pamene inductor waikidwa pa bolodi PCB, izo zikhoza kutsimikiziridwa kwamuyaya. Inde, ngati imagwira ntchito m'malo ovuta kapena osagwiritsidwa ntchito monga momwe ikufunira, moyo wake udzachepetsedwa moyenerera.
Ma inductors a SMD, ma chip inductors amakhala ndi mitundu 4, yomwe ndi chilonda cha waya, ma multilayer, oluka komanso opyapyala amafilimu. Mitundu iwiri yamtundu wa mabala a waya ndi mtundu wa laminated amagwiritsidwa ntchito kwambiri.
ali ndi zabwino maginito chotchinga katundu, mkulu sintered kachulukidwe, ndi wabwino makina mphamvu. Kapangidwe kaphatikizidwe, kudalirika kwakukulu; zabwino kutentha kukana ndi solderability; mawonekedwe okhazikika, oyenera kuyika ndi kupanga mawonekedwe okha.
