Iindaba zeShishini: Ii-Capacitors kunye nohlobo lwazo

Iintlobo zee-capacitors
1. Ii-capacitors ze-electrolytic

Ezi zii-capacitors ezi-polarized. I-anode okanye ii-terminals ezilungileyo zenziwe ngesinyithi kwaye ngokusebenzisa i-anodization, umaleko we-oxide uyadalwa. Ngoko ke lo maleko usebenza njenge-insulator. Kukho iintlobo ezintathu zee-capacitors ze-electrolytic ezisetyenziselwa izinto ezahlukeneyo. Kwaye ezi zinokuhlulwa ngolu hlobo lulandelayo.

Ii-capacitor ze-aluminium electrolytic
Ii-capacitor ze-electrolytic zeTantalum
Ii-capacitor ze-electrolytic ze-Niobium

A. Ii-capacitor ze-aluminium electrolytic

Kolu hlobo lwee-capacitors, i-anode okanye i-terminal ye-positive yenziwe nge-aluminium kwaye isebenza njenge-dielectric. Ezi capacitors zibiza kancinci kunezinye iintlobo zee-capacitors. Zinokunyamezela okukhulu kakhulu.

B. Ii-capacitor ze-electrolytic zeTantalum

Kwezi capacitors, isinyithi sisetyenziswa njenge electrode. Ezi ntlobo ziyafumaneka ngohlobo lwe lead kwaye zikwimo ye chip kwii capacitors zokufaka umphezulu ezinomthamo we (10 nf ukuya kwi 100 mf). Zisebenza kakuhle kakhulu. Zinokunyamezelana okuphantsi. Zizinzile kakhulu kwaye zithembekile.

C. Ii-capacitor ze-electrolytic ze-Niobium

Ezi azithandwa kakhulu njengee-capacitors ze-aluminium electrolytic kunye ne-Tantalum electrolytic capacitor. Zinexabiso eliphantsi kakhulu okanye zixabiso eliphantsi.

2. Ii-capacitor zeseramikhi

Ezi azithandwa kakhulu njengee-capacitors ze-aluminium electrolytic kunye ne-Tantalum electrolytic capacitor. Zinexabiso eliphantsi kakhulu okanye zixabiso eliphantsi.

•Iklasi I-Uzinzo oluphezulu kunye nelahleko ephantsi

1. I-capacitance echanekileyo kakhulu nezinzileyo
2.Uzinzo oluhle kakhulu lobushushu
3. ukunyamezelana okuphantsi (I 0.5%)
4.umthamo wokuvuza ophantsi
5.Izixhathisi kunye nezixhathisi

•Udidi lwesibini - ukuchaneka okuphantsi kunye nozinzo oluhambelana nee-capacitors zeklasi-I

1. ukusebenza kakuhle kwevolumu ephezulu kunee-capacitors zeklasi-I.
2. utshintsho olune-biasing voltage

3. Ii-capacitor zefilimu

♦ Kule mifanekiso ye-capacitors, ifilimu yeplastiki isetyenziswa njengesixhobo se-dielectric. Kukho iintlobo ezahlukeneyo ezifana ne-polyester poly propylene, i-polystyrene. Izinzile kakhulu kwaye ithembekile kakuhle, i-voltage yayo iphakathi kwe-IOU ukuya kwi-10 KV. Ezi zifumaneka kuluhlu lwe-PF kunye ne-MF.

4. I-Super capacitor

♦ Ikwaziwa ngokuba yi-ultra capacitor, zigcina inani elikhulu letshaja. Uluhlu lwe-capacitance luyahluka ukusuka kwi-farads ezimbalwa ukuya kwi-farads ezili-100. Umlinganiselo weVoltage uphakathi kwe-2.5 ukuya kwi-2.9

5. I-capacitor ye-Mica

♦ Ezi zichanekile kwaye zibonelela ngozinzo olufanelekileyo lobushushu. Zisetyenziswa kwizicelo zeRF kunye nakwiizicelo zevolthi ephezulu. Zibiza kakhulu yiyo loo nto ezi zithathelwa indawo zezinye ii-capacitor.

6. I-capacitor eguquguqukayo

♦ Ikwabizwa ngokuba yi-trimmer capacitor, zisetyenziselwa ukulinganisa izixhobo okanye ukwenza okanye ukulungisa. Kunokwenzeka ukutshintsha uluhlu oluthile. Kukho iintlobo ezimbini ze-trimmer capacitor.
♦ I-capacitor ye-ceramic kunye ne-air trimmer.
♦ I-capacitor encinci imalunga ne-0.5 PF, kodwa ingatshintshwa ukuya kuthi ga kwi-100PF.
Ezi capacitors ziyafumaneka ukuze zilinganiswe ngevolthi ukuya kuthi ga kwi-300v, ezi capacitors zisetyenziswa kwi-RF application oscillators kunye nee-tuning circuits.
