Mai shi ne Electrolytic Capacitor?

Mi ce Electrolytic Capacitor?

Takaitaccen capacitor

Capacitors su ne karamin kuli da tafkin kuli. Wanda yake na dama ya kunshi wata dama, ko kuma littattafai na kuli da aka fuskantar dangane da wata damar tana guduwa a cikin littattafan na kuli.

Tsarin mafiya na capacitor

Sayuwar capacitor

Kuli da tafki a kan kula na iya karama da zara a kan damar, yawanci a kan indaktar don samun LC oscillating circuit. Sayuwar capacitor shine ina bukatar zara zuwa liti, idan akwai matsala a kan damar, yana sauke zara zuwa liti kuma yana bukatar zara zuwa damar, wanda yake da shi a kan karamin zara.

Abubuwan da suka da muhimmanci a cikin capacitor

• Nominal capacitance: Yana nuna capacitance a cikin capacitor.

• Rated voltage: Mafi yawan DC voltage da za a iya karshen da ita a cikin capacitor a kan tsohon hawa mai girma da rated ambient temperature.

• Insulation resistance: Ratio ta DC voltage da aka karshen da ita a cikin capacitor don samun leakage current.

• Loss: Tafkin da capacitor ya karkashin da tsaye a kan lokacin da aka karkashin electric field.

• Frequency characteristics: Idan capacitor ya yi aiki a cikin frequency da ke da ita, yana da capacitance; idan yana kawo wannan frequency, yana da inductance.

Formula ta kalkulawa

Aiki na capacitor

• Coupling

• Filtering

• Decoupling

• High-frequency vibration suppression

Tsarin capacitor

• Aluminum electrolytic capacitor

Muhimman abubuwa: Karamin mafi yawa, yana iya da pulsating current mai yawa.

Na'urori: Mafi yawan karamin mafi yawa, mafi yawan leakage current.

• Tantalum electrolytic capacitor

Muhimman abubuwa: Mafi yawan adadin lokaci, mafi yawan tsari, mafi yawan karamin mafi yawa

Na'urori: Ba da takamfi da pulsating current, idan an kiranta, yana da kyau a faruwa

• Porcelain capacitor

Muhimman abubuwa: Lead inductance ita ce, frequency characteristics suna da kyau, dielectric loss ita ce

Na'urori: Adadin karamin mafi yawa da aka saka da vibration
