Lub capacitor yog ib qho khoom siv hluav taws xob tsim los khaws cov nqi hluav taws xob thiab lub zog teb. Muaj ntau ntau hom capacitor thiab lawv cov qauv tsim. Hauv tsab xov xwm no, peb yuav tham txog ceramic capacitors ntawm KM hom. Capacitors ntawm hom no yog siv rau hauv cov khoom siv hauv kev lag luam, hauv kev tsim cov cuab yeej ntsuas siab, xov tooj cua transmitters, nrog rau hauv kev lag luam tub rog.
KM ceramic capacitor muaj qhov ruaj khov, lawv tau tsim los ua haujlwm hauv cov hom mem tes, nrog rau hauv AC thiab DC circuits. Lawv yog cov yam ntxwv los ntawm siab adhesion ntawm daim hlau rau ceramics, raws li zoo raws li qeeb aging, uas ua kom ib tug tsawg coefficient ntawm capacitive kub instability. KM capacitors, nrog qhov me me me, muaj lub peev xwm siab (nce txog 2.2 microfarads). Txawm li cas los xij, qhov kev hloov pauv ntawm tus nqi capacitance nyob rau hauv kev khiav hauj lwm kub ntau rau KM ceramic capacitors ranges ntawm 10 mus rau 90%.
KM pawg H capacitor feem ntau siv hauvRaws li kev hloov pauv, thaiv, thiab lwm yam. Niaj hnub nimno KM ceramic capacitors yog tsim los ntawm kev nias nyob rau hauv siab rau hauv ib qho monolithic thaiv ntawm nyias metallized ceramic daim hlau. Vim yog lub zog siab ntawm cov khoom hais, nws tuaj yeem siv cov khoom nyias nyias, vim li ntawd, lub peev xwm ntawm cov capacitors tau txais, proportional rau chav tsev ntim, nce sharply.
KM hom capacitors kuj txawv ntawm lwm cov capacitors hauv lawv cov nqi siab. Qhov laj thawj yog vim li cas lawv siv cov hlau muaj txiaj ntsig hauv qab no (thiab lawv cov khoom sib xyaw) ua cov phaj dielectric: Ag, Pl, Pd. Feem ntau, palladium yog siv, thiab qhov no yog qhov tseeb uas txiav txim siab lawv tus nqi. Hauv qhov no, tsis yog tsuas yog cov khoom tshiab yog qhov xav tau zoo, tab sis kuj siv thiab txawm tias cov khoom siv tsis tau. Cov hlau zoo nkauj muaj nyob hauv KM3-6 hom capacitor. Lawv muab faib ua ob hom: palladium (KM H90) thiab platinum (KM H30). Muaj lwm cov subspecies ntawm KM capacitors ntawm pawg H30 - qhov no yog KM5 D, uas txawv ntawm H30 nyob rau hauv uas muaj ntau tsawg platinum nyob rau hauv lawv. Cov ntsiab lus ntawm precious hlau nyob rau hauv KM H90 yog 46.5 g ntawm palladium thiab 2.5 g ntawm platinum ib kilogram ntawm capacitors. Thiab nyob rau hauv capacitors ntawm KM H30 hom, nws yog 50 g ntawm platinum ib kilogram ntawm capacitors.
KM D pawg capacitors (ntsuab) muaj 40 gr. platinum, uas yog, 20% tsawg dua nyob rau hauv capacitors ntawm pawg H30 (ntsuab). Capacitors ntawm KM hom H90 pawg, muaj tsab ntawv V hauv lawv cov cim,muaj 10% cov hlau muaj txiaj ntsig ntau dua li cov capacitors ntawm pawg H90. Nyob rau hauv txoj kev xav, xws li capacitors yuav tsum tau kim dua lwm yam ceramic capacitors ntawm H90 ntsuab pawg. Thiab me me capacitors yuav tsum pheej yig dua. Hauv kev xyaum, tag nrho KM capacitors ntawm H90 ntsuab pab pawg raug nqi tib yam. Tus nqi ntawm KM capacitors ncaj qha nyob ntawm tus nqi ntawm cov hlau muaj txiaj ntsig, nrog rau cov nqi ntawm cov nqi refining. Feem ntau KM ceramic capacitors (daim duab qhia pom cov tsos ntawm KM hom capacitors) yog KM capacitors ntawm H90 pawg ntawm cov xim ntsuab thiab txiv kab ntxwv.
