Kev taw qhia txog cov khoom siv hluav taws xob ntau (G)

2. Capacitor

C. Kev faib tawm ntawm capacitor

(1) Raws li cov qauv ntawm peb pawg: taag capacitor, qhov sib txawv capacitor thiab zoo tuning capacitor.
Hloov pauv capacitor: nws yog tsim los ntawm cov txheej txheem ruaj khov thiab cov phaj txav tau, nws lub peev xwm tuaj yeem hloov pauv tsis tu ncua nrog kev sib hloov ntawm cov phaj txav tau.Ob pawg ntawm cov capacitors sib txawv tau nruab ua ke coaxial kev sib hloov, hu ua ob qhov kev sib txuas.Cov xov xwm tsis sib xws yog cov pa thiab polystyrene.Cua nruab nrab kuj tsis paub meej capacitor yog loj nyob rau hauv ntim thiab me me nyob rau hauv poob, yog li nws yog siv nyob rau hauv lub valve xov tooj cua.Polystyrene dielectric variable capacitors ua los ntawm kev kaw, me me, siv nyob rau hauv transistor xov tooj cua.
Semi-variable capacitor: kuj hu ua trimmer capacitor.Nws yog ua los ntawm ob los yog ob txheej ntawm cov hlau me me shrapnel nrog rau nruab nrab ntawm.Hloov qhov kev ncua deb lossis thaj tsam ntawm ob daim ntawv thaum koj kho.Nws nruab nrab muaj cua, ceramic porcelain, mica, zaj duab xis thiab lwm yam.

(2) Raws li cov duab: plug-in hom, thaj hom (SMD).

(3) Raws li lub hom phiaj: high zaus bypass, tsawg zaus bypass, lim, tuning, siab zaus coupling, tsawg zaus coupling, me me capacitor.

(4) Raws li cov khoom siv dielectric muab faib ua: ceramic nruab nrab, mica, ntawv, zaj duab xis, electrolytic capacitor.

(5) Mica capacitor: lub capacitor nrog mica li dielectric.Kev ua tau zoo heev, siab stability, siab precision.

(6) Ceramic capacitor: cov khoom siv ceramic nrog siab dielectric tas li thiab poob qis, me me ntim thiab me me inductance.

(7) Paper capacitor: lub electrode ntawm daim ntawv capacitor yog ua los ntawm txhuas ntawv ci los yog tin foil, qhov nruab nrab ntawm rwb thaiv tsev yog wax-soaked ntawv, folded rau hauv lub tog raj kheej, coated nrog noo noo-pov thawj cov ntaub ntawv, qee zaum lub plhaub yog kaw nrog hlau ntawv, folded rau hauv lub tog raj kheej, coated nrog noo noo-pov thawj cov ntaub ntawv, qee zaum lub plhaub yog kaw nrog hlau plhaub los txhim kho cov dej noo.Tus nqi qis, muaj peev xwm loj.Plhaub los txhim kho noo noo tsis kam.Tus nqi qis, muaj peev xwm loj.

(8) Zaj duab xis capacitors: ntau yam capacitors ua los ntawm polystyrene, polytetrafluoroethylene los yog polyester organic films es tsis txhob ntawm cov ntawv xov xwm.Me me, tab sis loj poob, tsis ruaj khov.Zoo, ua los ntawm ntau hom capacitor.Me me, tab sis loj poob, tsis ruaj khov.

(9) Electrolytic capacitor: capacitor nrog txhuas, ncej, saw, titanium thiab lwm yam hlau oxide zaj duab xis raws li qhov nruab nrab.Muaj peev xwm loj, tsis muaj kev ruaj ntseg.(ua tib zoo saib rau polarity thaum siv) loj, tsis zoo stability.
