Chitetezo cha Disk Varistor Electronics ESD
Mawonekedwe ndi Makhalidwe Aukadaulo
Kukula kochepa, mphamvu yothamanga kwambiri komanso kulolerana kwakukulu kwa mphamvu
Epoxy insulation encapsulation
Nthawi yoyankha: <25ns
Ntchito kutentha osiyanasiyana: -40 ℃～+85 ℃
Kukana kwa insulation: ≥500MΩ
Varistor voteji kutentha kokwanira: -0.5%/℃
Chip diameters: 5, 7, 10, 14, 20, 25, 32, 40mm
Kupatuka kovomerezeka kwa voliyumu ya varistor ndi: K± 10%
Kugwiritsa ntchito
Kutetezedwa kwamphamvu kwa ma transistors, diode, ICs, thyristors ndi semiconductor switching zinthu ndi zida zosiyanasiyana zamagetsi.
Mayamwidwe owonjezera a zida zapakhomo, zida zamafakitale, ma relay ndi ma valve apamagetsi
Electrostatic discharge ndi kuletsa chizindikiro chaphokoso
Kuteteza kutayikira, kusintha chitetezo cha overvoltage
Matelefoni, ma switch oyendetsedwa ndi pulogalamu ndi zida zina zoyankhulirana komanso chitetezo chambiri

FAQ
Kodi zoyambira za varistors ndi ziti?
(1) Makhalidwe achitetezo, mphamvu ya chiwopsezo cha gwero (kapena mphamvu yaposachedwa ya Isp=Usp/Zs) sichidutsa mtengo womwe watchulidwa, voteji yocheperako ya varistor saloledwa kupitilira mphamvu yolimbana ndi voltage (Urp) kuti chinthu chotetezedwa chingathe kupirira.
(2) Makhalidwe olimbana ndi mphamvu, ndiye kuti, varistor palokha iyenera kupirira mphamvu zomwe zatchulidwa panopa, mphamvu zowonongeka, ndi mphamvu zambiri pamene zovuta zambiri zimachitika chimodzi pambuyo pa china.
(3) Pali mikhalidwe iwiri ya moyo, imodzi ndi moyo wosalekeza wogwiritsa ntchito magetsi, ndiye kuti, varistor ayenera kugwira ntchito modalirika kwa nthawi yodziwika (maola) pansi pa kutentha komweku komanso kutentha kwamagetsi.Chachiwiri ndi moyo wokhudzidwa, ndiye kuti, kuchuluka kwa nthawi zomwe zingapirire modalirika zomwe zatchulidwa.
(4) Pambuyo pa varistor ikuphatikizidwa mu dongosolo, kuphatikizapo chitetezo cha "valve chitetezo", chidzabweretsanso zina zowonjezera, zomwe zimatchedwa "secondary effect", zomwe siziyenera kuchepetsa zachilendo. ntchito ya ndondomeko.
