Tayada

Farqiga u dhexeeya HVC iyo kuwa kale ee Awoodaha Korantada Sare leh.

Tayada; safka ayaa noqon doona kuwa aadka u danaynaya badanaana walaac ka keena saaxiibo cusub oo halis ah!
Kuwa soo socdaa waa sharraxaad weyn oo loogu talagalay cabbirrada farsamo ee muhiimka ah:

Resistance madhxiyaama IR sida magaceedu ku taliyo waa iska caabin ka imaatinka hawada
waxay ka ilaalisaa qalabka korantada wareegga gaagaaban. Qiimaha guud ahaan waa mid aad u sarreeya marka la eego Mega-ohm ama Mohm.

Wehliyaha Heerkulkawaxay kuxirantahay hadba middaka loo yaqaan 'dielectric isClass 1orClass 2'. Xaraash
capacitor (gaar ahaan fasalka '2') badanaa wuxuu leeyahay cunsur sare, isku xirnaan sarreeya oo isdabajoog ah.

Cunsunka faafida (tan δ): ama DF waxaa lagu qeexaa inay yihiin saamiga ESR iyo fal-celinta kartida. Waa tan
Muranka kala-baxa ayaa sidoo kale loo yaqaanaa isku-dhefka xagasha luminta waxaana badanaa lagu muujiyaa boqolkiiba.
Jaangooyooyinka la aqoonsan yahay waxay muujinayaan qodobka kala-baxa ah ee loo yaqaan 'frequencies' gaar ahaan 120Hz Aluminium
qalabka korantada elektrolytic iyo Tantalum halka loogu talagalay kuwa awood u leh filimka waa 1 kHzand iyo 1 MHz ee loogu talagalay alwaaxa sibidhka.

Bixinta Qayb Ahaan (PD): waa dheecaan koronto ama iftiin keenaya qayb yar oo ka mid ah dahaarka
inta u dhaxaysa laba qabashada korantada.PD wuxuu ku dhici karaa meel kasta oo ka mid ah nidaamka korantada, meesha garoonka korantada
xoogga ayaa ka sarreeya xoog jabidda qaybtaas maaddada dahaarka ah
dahaar adag, dusha sare ee maaddada dahaarka waxyaabaha wasakhaysan ama cilad la’aan awgeed, gudaha gaasaska
dahaaridda dareeraha ama ku wareegsan gaaska ku shaqeeya gaaska (dhaqdhaqaaqa corona).

Qalabka Kala Duwan:

Tusaale ahaan, a Z5U capacitor wuxuu shaqeyn doonaa laga bilaabo +10 ° C illaa +85 ° C oo leh isbadal dhanka awooda ah ugu badnaan + 22% ilaa -56%. X7R capacitor wuxuu ka shaqeyn doonaa -55 ° C illaa +125 ° C oo leh isbadal dhanka awooda ah ugu badnaan ± 15%. HVC's N4700 Dielectric Material: oo la mid ah shirkad kale, koronto-yaqaan ayaa go'aamiya muuqaalka ugu weyn ee koofiyadaha. HVC waxay kubixisaa 3 sano iyo malaayiin $ ikhtiraac ah strontium titanate, oo ah nooca N4700.ThisN4700 waxeey siisaa muuqaal aad uwanaagsan oo heer sare ah, iska caabin heer sare ah oo dahaar weyn iyo cunsur yar yar ilaa 20 sano.
