Ib qho axial/lead MLCC capacitor uas tsim los ntawm BEC yog ib hom tshwj xeeb ntawm multilayer ceramic capacitor tsim nrog radial leaded terminations (ob lub hlau lead txuas los ntawm qhov opposite xaus ntawm lub cev ceramic - tawm ntawm qhov chaw-mount (SMD) chip format of standard MLCCs (uas muaj kev sib txuas ntawm cov khoom sib txuas rau PC2). cov core stacked ceramic dielectric/electrode qauv ntawm MLCCs nrog rau ntawm - qhov radial lead tsim ntawm cov tsoos discrete capacitors rau choj SMD MLCC kev ua tau zoo thiab dhau los ntawm - qhov sib dhos ua ke MLCC yog tsis tshua pom tam sim no, tab sis nws tseem tuaj yeem pom hauv qee qhov kev siv tsawg.

Yam ntxwv
Kub Coefficient of Capacitance (TCC)
Ib qho tseem ceeb tshaj plaws metric rau qhov kub thiab txias, txhais los ntawm dielectric:
C0G/NP0 (Class 1 dielectrics): Zero -zero TCC (± 30ppm /℃los ntawm -55℃rau +125} degree), ultra-ruaj khov capacitance tsis muaj qhov tseem ceeb drift hla kub.
X7R/X5R (Class 2 dielectrics): Kev ruaj ntseg nruab nrab (X7R: -55℃~ +150℃, ΔC/C Tsawg dua lossis sib npaug ± 15%; X5R: -55℃~ +85℃, ΔC / C Tsawg dua lossis sib npaug ± 15%).
Y5V/Z5U (Class 2 low-stability dielectrics): Tsis zoo kub stability (Y5V: -}30℃~+85℃, ΔC/C Tsawg dua los yog sib npaug rau +20}%/-80%)-siab tshaj capacitance ntom, tsis tshua muaj nqi hluav taws xob.
Dav dav:0.1pF (RF precision) mus rau 100μF (siab-cap decoupling) - deb dua capacitance ceev tshaj radial ceramic disc capacitors (tso rau qis nF) thiab sib tw nrog me me radial electrolytics.
Dielectric{0}} nyob ntawm qhov ceev:Chav kawm 2 dielectrics (X7R / X5R) xa cov peev txheej siab tshaj plaws (μF ntau) hauv cov pob khoom THT compact; Chav Kawm 1 (C0G/NP0) muaj peev xwm tsawg (pF/nF) tab sis ultra-stability.
DC bias effect:Tam sim no nyob rau hauv chav kawm 2 dielectrics (X7R/X5R) - capacitance txo nrog siv DC voltage (xws li, 10μF/16V X7R yuav poob mus rau 5μF ntawm 8V DC bias); negligible rau C0G/NP0 (tsis muaj kev xav tsis zoo).

FAQ
Q1: Nws txawv ntawm radial MLCC li cas?
A1: Axial: Leads los ntawm qhov sib txawv (xws li ib qho kev tiv thaiv), thaum radial hom nrog ob qho tib si coj los ntawm tib kawg (zoo li feem ntau electrolytics)
Feem ntau ntawm - qhov MLCCs yog radial; axial hom tsis tshua muaj tab sis siv qhov sib txawv ntawm cov hlau lead / orientation teeb meem.
Q2: Puas axial MLCC capacitors raug kev txom nyem los ntawm DC bias nyhuv zoo li chips?
A2: Yog lawm. Qhov no yog ib tug tseem ceeb misconception. DC kev tsis ncaj ncees yog cov khoom vaj khoom tsev, tsis yog cov khoom ntim khoom. A Chav Kawm 2 (X7R, X5R, Y5V) axial MLCC yuav poob lub peev xwm nrog cov hluav taws xob siv hluav taws xob ib yam li nws cov chips counterpart. Tsuas yog Class 1 (C0G/NP0) xwb thiaj tsis muaj zog.
Q3: Puas axial MLCC capacitors tawg zoo li nti MLCC capacitors?
A3: Tsawg dua tab sis tseem ua tau. Kev pheej hmoo tawg yog qis dua vim ua rau muaj kev ntxhov siab
Tseem zam dhau board flexing. Tsis txhob khoov coj txoj cai ntawm lub cev. Siv lub zog kom zoo nyob rau hauv siab -ib puag ncig kev co
Q4: Kuv tuaj yeem paub cov cim li cas?
A4: Txheem 3-tus lej code. Thawj ob tus lej: Cov lej tseem ceeb. Tus lej thib peb: Tus lej sib npaug (tus lej zeros). Tsab ntawv: Kev kam rau siab (J=± 5%, K=± 10%, M=± 20%) Voltage: Feem ntau luam tawm (piv txwv li, "1K"=1000V). Piv txwv li: "104K 1K"=10 × 10⁴ pF=100,000pF=0.1µF, ± 10%, 1000V ntsuas
