Gen anpil kalite kondansateur, ak diferan kalite kondansateur gen fonksyon diferan. Senaryo aplikasyon kondansateur komen sitou gen ladan sa ki annapre yo:
1. Energy storage. Since the energy that can be stored by the electrolytic capacitor is relatively large, it can be used as a backup power source after the system is powered down to ensure the integrity of the system's stored data.
2. Filtrage. Kondansateur nan kapasite diferan gen enpedans diferan nan siyal nan frekans diferan. Lè w chwazi kondansateur nan kapasite ki apwopriye, siyal entèferans ak siyal bri yo ka filtre soti pou fè ekipman pou pouvwa a pi estab ak siyal la douser.
3. Couplage. Sèvi ak karakteristik nan kondansateur a separe DC a ak AC, eleman DC nan siyal la ka efektivman filtre ak eleman nan AC kenbe, pou ke siyal la ka transmèt nan pwochen sikwi nivo -.
4. Akor. Kous la sonan LC ka pwodwi yon sèten fòm ond frekans, ak chanje gwosè a nan valè a kondansateur ka chanje gwosè a nan frekans nan sonorite reyalize frekans siyal nou bezwen an.
5. Reta. Chaje a ak egzeyat nan kondansateur a gen yon sèten tan. Pi gwo kapasite a, se pi long tan an chaje ak egzeyat. Dapre prensip sa a, yon senp fonksyon reta sikwi ka reyalize.
6. Analiz echèk. Echèk kondansateur sitou gen ladan twa kalite: sikwi louvri, kous kout ak drift paramèt. Kout kous se fenomèn echèk komen nou an, espesyalman nan aplikasyon sikwi pouvwa. Kondansateur kout sikwi trè danjere epi li ka fasilman lakòz aksidan chalè ak dife, kidonk li nesesè fè bon pwoteksyon tablo sikwi ak derating itilizasyon paramèt kondansateur.
7. Howling analysis. In the application of MLCC capacitors, the phenomenon of capacitor whistling sometimes occurs. This phenomenon is called "electrostriction". This phenomenon is due to the mechanical deformation of the ferroelectric ceramic material of the MLCC capacitor under the action of voltage. The deformation is very small, usually 1pm1nm. The deformation is transmitted to the circuit board and causes the substrate to vibrate. If the vibration frequency is just within the audible range of the human ear, it can be heard by us, as if the capacitor is whistling. Same. One of the solutions is to replace capacitors with low dielectric constant materials, because the lower the dielectric constant of the capacitor, the smaller the "electrostrictive" effect.
