QUALITY ikholomu izoba nesithakazelo kakhulu futhi ikakhulukazi ukukhathazeka ngamakhasimende amasha!
Ngezansi incazelo ezinkulu nemingcele ezibalulekile technical:
Resistance ukwahlukanisa noma i-IR njengoba igama liphakamisa ukuphikiswa kwalo
ukwahlukanisa. IR empeleni ivikela imishini kagesi kusuka kusifunda esifushane. Amanani we-IR
ngokuvamile ziphakeme kakhulu ebangeni leMega-ohm noma i-Mohm.
Temperature Coefficient kuya ngokuthi i-dielectric i-Class 1 noma i-Class 2. A ceramic
I-capacitor (ikakhulukazi isigaba 2) imvamisa inesici sokushabalalisa esiphakeme, imvamisa yokuphindaphindeka kokushabalalisa.
Isici sokusabalalisa (tan δ):noma i-DF ichazwa njengobungako be-ESR nokuphendula okusebenzayo. Yi-
isici sokusabalalisa saziwa nangokuthi i-tangent ye-angle yokulahleka futhi ivame ukuboniswa ngamaphesenti.
Izindinganiso ezaziwayo ziveza isici sokusabalalisa kumaza athile ikakhulukazi i-120Hz ye-Aluminium
ama-electrolytic ne-Tantalum capacitors ngenkathi ama-capacitors wamafilimu eyi-1 kHz ne-1 MHz yama-capacitor e-ceramic.
Ukuchitha esinqunyiwe (PD): kuyinto khulula kagesi noma inhlansi bridges ingxenye encane the ukwahlukanisa
phakathi ezimbili beqhuba electrodes.PD singenzeka nganoma yingasiphi ohlelweni ukwahlukanisa, lapho insimu kagesi
amandla idlula amandla ukuwohloka ukuthi ingxenye material.PD nangokuvikela kungavuka voids ngaphakathi
ukwahlukanisa okuqinile, ngaphesheya kwamanzi nangokuvikela impahla ngenxa contaminants noma semfene, ngaphakathi gas Bubbles
e ukwahlukanisa liquid noma eduze electrode e gas (corona umsebenzi).
