Nkhani Zamakampani: Ma Capacitor ndi mtundu wawo

Mitundu ya ma capacitor
1. Ma capacitor amagetsi

Izi ndi ma capacitor ozungulira. Ma anode kapena ma positive terminals amapangidwa ndi chitsulo ndipo kudzera mu anodization, gawo la oxide limapangidwa. Chifukwa chake gawoli limagwira ntchito ngati insulator. Pali mitundu itatu ya ma electrolytic capacitors omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana. Ndipo awa akhoza kugawidwa m'magulu awa:

Ma capacitor a electrolytic a aluminiyamu
Ma capacitor a Tantalum electrolytic
Ma capacitor a electrolytic a Niobium

A. Ma capacitor a electrolytic a aluminiyamu

Mu mtundu uwu wa ma capacitor, anode kapena positive terminal imapangidwa ndi aluminiyamu ndipo imagwira ntchito ngati dielectric. Ma capacitor awa ndi otsika mtengo kwambiri kuposa mitundu ina ya ma capacitor. Ali ndi kulekerera kwakukulu.

B. Ma capacitor a Tantalum electrolytic

Mu ma capacitor awa, chitsulo chimagwiritsidwa ntchito ngati electrode. Mitundu iyi imapezeka mumtundu wa lead komanso mu mawonekedwe a chip kuti ma capacitor oyika pamwamba akhale ndi mphamvu (10 nf mpaka 100 mf). Ili ndi mphamvu zambiri za voliyumu. Ili ndi kulekerera kochepa. Ndi yokhazikika komanso yodalirika.

C. Ma capacitor a Niobium electrolytic

Izi sizitchuka kwambiri monga ma capacitor a Aluminium electrolytic ndi Tantalum electrolytic capacitor. Zili ndi mtengo wotsika kwambiri kapena mtengo wake ndi wotsika.

2. Ma capacitor a ceramic

Izi sizitchuka kwambiri monga ma capacitor a Aluminium electrolytic ndi Tantalum electrolytic capacitor. Zili ndi mtengo wotsika kwambiri kapena mtengo wake ndi wotsika.

•Kalasi I - Kukhazikika kwakukulu ndi kutayika kochepa

1. capacitance yolondola kwambiri komanso yokhazikika
2.kukhazikika kwabwino kwambiri kwa kutentha
3. kulekerera kochepa (I 0.5%)
4.kutsika kwa kutayikira kwamakono
5. Wosagonja komanso wosasunthika

•Kalasi II - kulondola kotsika komanso kukhazikika komwe kumayenderana ndi ma capacitor a kalasi I

1.mphamvu yochuluka ya volumetric kuposa ma capacitor a kalasi I.
2.kusintha ndi mphamvu yamagetsi yozungulira

3. Ma capacitor a filimu

♦ Mu ma capacitor a filimuyi, filimu ya pulasitiki imagwiritsidwa ntchito ngati zinthu zamagetsi. Pali mitundu yosiyanasiyana monga polyester poly propylene, polystyrene. Ili ndi kukhazikika kwakukulu komanso kudalirika kwabwino, mphamvu yake yamagetsi ndi IOU mpaka 10 KV. Izi zimapezeka mu PF ndi MF.

4. Super capacitor

♦ Imadziwikanso kuti ultra capacitor ndipo imasunga mphamvu zambiri. Mphamvu zake zimasiyana kuyambira ma farad ochepa mpaka ma farad 100. Voltage rating ndi pakati pa 2.5 mpaka 2.9.

5. Kachipangizo ka Mica

♦ Izi ndi zolondola ndipo zimapereka kukhazikika kwa kutentha kwabwino. Zimagwiritsidwa ntchito mu ma RF applications komanso ma high voltage applications. Ndi okwera mtengo ndipo izi zimasinthidwa ndi ma capacitor ena.

6. Kampakitala wosinthika

♦ Imadziwikanso kuti trimmer capacitor. Imagwiritsidwa ntchito poyesa zida kapena kupanga kapena kukonza. N'zotheka kusintha mtundu winawake. Pali mitundu iwiri ya trimmer capacitor.
♦ Capacitor ya Ceramic ndi Air trimmer.
♦ Capacitor yocheperako ndi pafupifupi 0.5 PF, koma imatha kusinthidwa mpaka 100PF.
Ma capacitor awa amapezeka kuti azitha kugwiritsa ntchito mphamvu yamagetsi mpaka 300v, ma capacitor awa amagwiritsidwa ntchito mu ma RF application oscillators ndi ma tuning circuits.
