Lub lauj kaub Core
Cov tub ntxhais tseem qhwv ib ncig ntawm tus ncej thiab windings, muab EMI tiv thaiv zoo heev. Lub lauj kaub cores ua raws li IEC cov qauv, tso cai rau kev sib hloov tau zoo thaum tsim khoom. Lawv muab cov kev xaiv thav duab yooj yim (tsis muaj pins) nrog rau PCB-mountable thav ntawv (nrog pins). Vim lawv tsim, lub lauj kaub cores kim dua piv rau lwm cov cores ntawm qhov loj me. Txawm li cas los xij, lawv cov duab tsis zoo rau kev siv hluav taws xob zoo, yog li tsis tsim nyog rau cov ntawv thov hluav taws xob siab.
RM Core
Piv rau lub lauj kaub cores, RM cores muaj symmetrical sab txiav tawm, uas txhim kho cov cua sov dissipation thiab pab txhawb cov hlau lead loj dua. Lawv txuag kwv yees li 40% ntawm qhov chaw teeb tsa piv rau lub lauj kaub cores. RM cores tuaj nyob rau hauv ob qho tib si pinless thiab pinned thav duab xaiv thiab tuaj yeem ntsia tau siv ib khub clips. Lawv tuaj yeem ua tau zoo li lub tiaj tus (tsim rau cov transformers tiaj tus los yog ncaj qha mounting ntawm PCBs nrog pre-tsim windings). Txawm hais tias lawv cov nyhuv thaiv tsis zoo li lub lauj kaub cores, nws tseem yog qhov tsim nyog.
EC, ETD, thiab EER Cores
Cov hom tseem ceeb no txuas qhov sib txawv ntawm E cores thiab pot cores. Zoo li E cores, lawv muab qhov chaw txaus rau cov xaim loj loj, ua rau lawv tsim nyog rau qhov tsis tshua muaj hluav taws xob siab tam sim no hloov-hom hluav taws xob hloov pauv. Cov cores no kuj ua tau zoo nyob rau hauv tshav kub dissipation. Lawv cylindrical center ncej txo qhov ntev winding thiab tooj liab poob, tso cai rau ntau zog tso zis. Lub cylindrical ncej tsim tshem tawm txoj kev pheej hmoo ntawm kev puas tsuaj ntawm cov hlau thaiv thaum lub sij hawm winding, tsis zoo li cov npoo ntse ntawm cov duab plaub.
PQ Core
PQ cores yog tsim tshwj xeeb rau cov khoom siv hluav taws xob inductors thiab transformers. PQ cov duab optimizes qhov sib piv ntawm cov tub ntxhais ntim, thaj chaw saum npoo, thiab qhov chaw winding. Qhov kev tsim no tso cai rau cov cores tsawg los muab qhov siab tshaj plaws inductance thiab winding cheeb tsam siv. Nws ua kom tau txais qhov siab tshaj plaws tso zis hluav taws xob hauv qhov tsawg tshaj plaws transformer ntim thiab qhov hnyav thaum nyob hauv qhov chaw PCB tsawg. Kev teeb tsa tuaj yeem ua tiav siv cov clips, ua kom muaj kev ruaj ntseg haum. Cov qauv tsim tau zoo kuj ua kom muaj kev sib nqus sib nqus ntau dua, ua rau muaj tsawg dua hotspots piv rau lwm cov qauv tseem ceeb.
EP tub ntxhais
EP core nta ib puag ncig hauv nruab nrab kem uas tag nrho qhwv cov windings tshwj tsis yog qhov kawg ntawm kev sib cuag nrog PCB, muab kev tiv thaiv zoo heev. Cov duab tshwj xeeb no txo qis qhov cuam tshuam ntawm qhov sib txawv tsim thaum lub sij hawm sib dhos ntawm ob lub ntsiab lus thiab muab ntau dua ntim-rau-qhov chaw siv piv.
Toroidal Core
Rau cov tuam txhab, toroidal cores yog qhov kev xaiv pheej yig tshaj plaws, nrog cov nqi qis dua ntawm cov tub ntxhais sib piv. Kev siv tus ncej tshem tawm cov nqi sib dhos ntxiv. Lawv haum rau lub tshuab winding thaum tsim nyog thiab muab cov khoom tiv thaiv zoo.
