1. Hōʻike ʻia ka capacitor e ka "C" me nā helu ma ke kaapuni (e like me C13 ʻo ia ka capacitor helu 13). Hoʻokumu ʻia ka capacitor i ʻelua kiʻiʻoniʻoni metala kokoke i kekahi i kekahi, i hoʻokaʻawale ʻia e kahi mea insulating ma waena. ʻO nā hiʻohiʻona o ka capacitor ʻo ia ka DC i AC.

ʻO ka nui o ka mana capacitor ka nui o ka ikehu uila hiki ke mālama ʻia. ʻO ka hopena pale o ka capacitor ma ka hōʻailona AC i kapa ʻia ʻo capacitive reactance, e pili ana i ke alapine a me ka capacitance o ka hōʻailona AC.

ʻO ka mana XC = 1 / 2πf c (f hōʻike i ke alapine o ka hōʻailona AC, C ke hōʻike i ka mana)

ʻO nā ʻano capacitors maʻamau i hoʻohana ʻia i nā kelepona ʻo ia nā capacitors electrolytic, capacitors ceramic, chip capacitors, monolithic capacitors, tantalum capacitors a me polyester capacitors.

 

2. Keʻano o kaʻikeʻana:ʻO keʻano o kaʻikeʻana o ka capacitor e like me keʻano o kaʻikeʻana o ka mea pale, i māheleʻia iʻekolu mauʻano: keʻano maʻamau pololei, keʻano maʻamau kala a me keʻano maʻamau helu. Hōʻike ʻia ka ʻāpana kumu o ka capacitor e Farah (F), a ʻo nā ʻāpana ʻē aʻe: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).

Ma waena o lākou: 1 farad = 103 millifarad = 106 microfarad = 109 nanofarad = 1012 picofarad

Hoʻopili pololei ʻia ka waiwai capacitance o kahi capacitor nui-nui ma ka capacitor, e like me 10 uF / 16V.

Hōʻike ʻia ka waiwai capacitance o kahi capacitor me kahi liʻiliʻi e nā leka a i ʻole nā ​​helu ma ka capacitor

Ka helu palapala: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF

Hōʻike kikohoʻe: ʻO ka maʻamau, hoʻohana ʻia nā huahelu ʻekolu e hōʻike i ka nui o ka hiki, ʻo nā huahelu mua ʻelua e hōʻike ana i nā huahelu koʻikoʻi, a ʻo ka huahelu ʻekolu ka hoʻonui.

No ka la'ana: 102 'o ia ho'i 10 × 102PF = 1000PF 224 'o ia ho'i 22 × 104PF = 0.22 uF

3. Hapa papa o ka capacitance

Hoailona: FGJKLM

ʻAe ʻia ka hewa ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%

No ka laʻana: he capacitor seramika o 104J e hōʻike ana i kahi mana o 0.1 uF a me kahi hewa o ± 5%.
