CMKD-1770A Series yog qhov loj tshaj plaws thiab muaj zog tshaj SMD Moulded Inductor hauv CMKD kab. Nws yog tsim los ntawm 17.15 mm × 17.15 mm hneev taw thiab yog tsim los rau qhov muaj peev xwm tshaj plaws tam sim no thiab qhov ceev tshaj plaws tam sim no.

Qhov siab -kev ua tau zoo SMD Moulded Inductor yog tsim los rau cov kev siv fais fab uas xav tau tshaj plaws, muab qhov tshwj xeeb saturation tam sim no (Isat) txog li 85.5A thiab inductance ntau txog 100µH. CMKD-1770A's ib-daim, thaiv kev tsim cov hlau nplaum ua kom tsis muaj EMI thiab cov tub ntxhais poob qis, ua rau nws qhov kev daws teeb meem zoo tshaj plaws rau siab - zog, siab zaus (txog 5MHz) server VRMs. Cov qauv no yog qhov zoo tagnrho rau cov kev cai fais fab inductor tov ua nyob ib ncig ntawm qhov kev ua tau zoo tshaj plaws, thiab CMKD-1770A ua raws li kev ntseeg siab DC fais fab inductor hauv cov tshuab nyuaj.
