Bypass capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv bypass Circuit Court yog hu ua bypass capacitor. Yog tias koj xav tau tshem tawm cov teeb liab hauv qee qhov zaus ntawm lub teeb liab hauv Circuit Court, koj tuaj yeem siv lub bypass capacitor circuit. Nyob ntawm qhov zaus ntawm lub teeb liab tshem tawm, muaj txhua hom bypass capacitor. Zaus domain (tag nrho AC signals) bypass capacitor circuits thiab high zaus bypass capacitor circuits.
Neutralizing capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv nruab nrab Circuit Court hu ua neutralizing capacitor. Hauv xov tooj cua high-frequency thiab intermediate-frequency amplifiers thiab TV high-frequency amplifiers, no neutralizing capacitor Circuit Court yog siv los tshem tawm nws tus kheej excitation.
Timing capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv lub sij hawm Circuit Court hu ua lub sij hawm capacitor. Timing capacitor circuits yog siv nyob rau hauv circuits uas xav tau lub sij hawm tswj los ntawm capacitor charging thiab tawm. Lub capacitor plays lub luag haujlwm hauv kev tswj lub sijhawm.
Integrating capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv lub integrating circuit hu ua integrating capacitor. Nyob rau hauv lub synchronization sib cais Circuit Court ntawm hluav taws xob muaj peev xwm teb scanning, no integrating capacitor Circuit Court yuav siv tau los extract lub teb synchronization teeb liab los ntawm lub teb composite synchronization teeb liab.
Differential capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv txawv Circuit Court yog hu ua txawv capacitor. Txhawm rau kom tau txais cov cim taw qhia ncov nyob rau hauv lub flip-flop Circuit Court, qhov sib txawv capacitance Circuit Court yog siv kom tau txais lub ncov mem tes taw qhia teeb liab los ntawm ntau hom (tsuas yog cov mem tes duab plaub).
Kev them nyiaj yug capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv cov nyiaj them nqi hluav taws xob yog hu ua them nyiaj capacitor. Hauv kev them nyiaj bass thaj tsam ntawm lub lawj, qhov kev them nyiaj tsawg zaus capacitor Circuit Court yog siv los txhim kho cov teeb liab tsawg zaus hauv cov teeb liab playback. Tsis tas li ntawd, muaj ntau zaus Compensation capacitor Circuit Court.
Bootstrap capacitor muaj nuj nqi: Lub capacitor siv nyob rau hauv bootstrap Circuit Court yog hu ua bootstrap capacitor. Feem ntau siv OTL fais fab amplifier tso zis theem circuits siv qhov bootstrap capacitor Circuit Court kom me ntsis nce qhov zoo ib nrab-lub voj voog amplitude ntawm lub teeb liab los ntawm kev tawm tswv yim zoo.
Kev ua haujlwm ntawm zaus faib cov capacitor: Lub capacitor nyob rau hauv lub zaus dividing Circuit Court hu ua zaus dividing capacitor. Nyob rau hauv tus hais lus zaus faib Circuit Court ntawm tus neeg hais lus, zaus dividing capacitor Circuit Court yog siv los ua lub tweeter ua hauj lwm nyob rau hauv lub high zaus band thiab lub mid-frequency speaker ua hauj lwm nyob rau hauv nruab nrab-frequency band. , lub subwoofer ua haujlwm nyob rau hauv qhov tsawg zaus band.
Load capacitance muaj nuj nqi: yog hais txog qhov zoo sab nraud capacitance uas txiav txim siab load resonant zaus ua ke nrog quartz siv lead ua resonator. Feem ntau siv cov qauv tsim nyog rau kev thauj khoom muaj peev xwm yog 16pF, 20pF, 30pF, 50pF thiab 100pF. Lub load capacitance tuaj yeem hloov kho kom haum raws li qhov xwm txheej tshwj xeeb.
