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: Dab tsi yog qhov txawv ntawm radial MLCC capacitor thiab radial ceramic disc capacitor?
A2: Radial MLCC capacitor: Stacked ceramic dielectric thiab sab hauv hlau electrodes (monolithic raug rho tawm haujlwm tub ntxhais), siab capacitance ceev (1pF txog 100μF) hauv pob THT compact.
Radial disc capacitor: Ib qho - txheej ceramic dielectric nrog rau sab nraud electrodes, tsawg capacitance ceev (1pF txog 100nF) thiab kev ua haujlwm tsawg.
Radial MLCCs yog qhov siab -kev ua tau zoo hloov kho rau THT circuits uas xav tau kev muaj peev xwm ntau dua li lub kaus mom disc tuaj yeem muab tau.
Q2: Puas yog radial MLCC capacitor polarized lossis tsis yog -polarized?
A2: Tag nrho cov radial MLCCs tsis yog -polarized. Lawv tsis muaj qhov zoo lossis qhov tsis zoo, tsis zoo li radial electrolytic lossis tantalum capacitors. Qhov no tshem tawm qhov kev pheej hmoo ntawm kev thim rov qab- qhov hluav taws xob puas thiab ua kom yooj yim rau PCB layout (tsis muaj kev taw qhia coj mus kuaj).
Q3: Dab tsi cov qauv txhuas qhov sib txawv thiab qhov loj me muaj rau BEC's radial MLCCs?
A3: Lead spacing (center-rau-center): 5mm, 7.5mm, 10mm ( haum universal breadboards, protoboards, thiab THT PCB hneev taw) - 5mm / 10mm yog qhov ntau tshaj.
Lead txoj kab uas hla: 0.5mm, 0.8mm (raws li tus qauv PCB los ntawm - qhov laum qhov ntau thiab tsawg: 0.8mm / 1.0mm).
Lead ntev: 10mm, 15mm (txiav- mus rau - ntev kev xaiv muaj rau kev txiav txim ntau ntau).
Q4: Vim li cas kuv thiaj li yuav tsum xaiv lub radial MLCC tshaj lub radial electrolytic / tantalum capacitor?
A4: Xaiv lub radial MLCC thaum koj xav tau:
Tsis yog-polarity: Tsis thim rov qab-voltage txaus ntshai (tseem ceeb rau cov kab hluav taws xob tsis raug cai).
Tsis muaj thermal runaway / leakage: Ceramic kev tsim kho (tsis yog -electrochemical) → tsis muaj electrolyte ziab (electrolytics) lossis kev puas tsuaj loj (tantalum nyob rau hauv overvoltage).
Kev khiav hauj lwm kub: -55℃~ +150℃(vs. electrolytics: feem ntau -40℃~+105℃).
Tsawg ESR: Rau siab -frequency ripple filtering (deb qis ESR tshaj electrolytics).
Radial electrolytics / tantalums tseem zoo dua rau qhov muaj peev xwm siab heev (mF ntau yam) lub zog ua kom du -pair radial MLCCs nrog lawv rau hybrid THT fais fab circuits.
