Intshayelelo yamacandelo e-elektroniki aqhelekileyo (E)

1. Abaxhathisi (5)

E. Thermistor
I-Thermistor: Isixhasi senzwa esinokumelana nokwahluka ngokweqondo lobushushu.Ngokwee-coefficients zeTemperature ezahlukeneyo, zinokwahlulwa zibe yi-Positive Temperature Coefficient Thermistor (PTC, oko kukuthi, i-Positive Temperature Coefficient Thermistor) kunye neThermistor engalunganga ye-Temperature Coefficient Thermistor (NTC, i-Negative Temperature Coefficient Thermistor).I-coefficient thermistors ye-coefficient thermistors, enokuthi ukuchasana kwayo kunyuke ngokunyuka kweqondo lokushisa, kunye ne-thermistors ye-coefficient ye-coefficient, ukuxhatshazwa kwayo kuncipha ngokunyuka kweqondo lokushisa, zombini zizixhobo ze-semiconductor.

F. resistors Photosensitive
Ukumelana ne-Photosensitive: ekwaziwa ngokuba ityhubhu ye-photoconductive, izinto ezisetyenziswa ngokuqhelekileyo ukuveliswa kwe-cadmium sulfide, ngaphezu kwe-selenium, i-aluminium sulfide, i-lead sulfide, i-bismuth sulfide kunye nezinye izinto.Ezi zixhobo zinepropati yokunciphisa ngokukhawuleza ukuchasana phantsi kwee-wavelengths ezithile zokukhanya.Oku kungenxa yokuba abathwali bentlawulo abaveliswa kukukhanya babandakanyeka ekuqhubeni nasekuqhubeni phantsi kwesenzo sentsimi yombane esetyenzisiweyo.Ii-electron zibaleka kwipali elungileyo yonikezelo lwamandla, kwaye imingxuma ibaleka kwipali engalunganga yonikezelo lwamandla, ukuze ixabiso lokumelana ne-photosensitive resistor lehla ngokukhawuleza.Ngokweempawu ze-spectral ze-photoresistors, zinokwahlulwa zibe ziintlobo ezintathu ze-photoresistors: i-ultraviolet photoresistors, i-infrared photoresistors kunye ne-photoresistors yokukhanya ebonakalayo.

G. Metal Film Resistors
IMetal Film Resistors: Enye yeeFilimu Resistors.Yamkela itekhnoloji yokugquma i-vacuum ephezulu yobushushu ukuncamathisela i-nickel-chromium okanye i-alloy efanayo kumphezulu wentonga ye-porcelain ukwenza ifilimu yesikhumba.Emva kokusika kunye nokulungelelanisa ixabiso lokumelana, ixabiso lokugqibela lokuchasana ngokuchanekileyo liphunyeziwe.Emva koko, ukudibanisa okufanelekileyo kongezwa ukusika kwaye umphezulu ugqunywe ngokhuseleko lwe-epoxy resin seal.Ngenxa yokuba kukunganyangeki okukhokelayo, ukufakela kunye nokugcinwa kwencwadi elula, esetyenziswa kwizixhobo ezininzi zekhaya, unxibelelwano, izixhobo kunye neemitha.Ukumelana nokushisa kwayo, amandla engxolo, i-coefficient yeqondo lokushisa, i-voltage coefficient kunye nezinye iimpawu zombane zingcono kune-carbon film resistors.Xa kuthelekiswa ne-carbon film resistor, le resistor inomthamo omncinci, ingxolo ephantsi, ukuzinza okulungileyo, kodwa ixabiso eliphezulu.Ihlala isetyenziswa ngokubanzi njengento echanekileyo kunye nozinzo oluphezulu, kwaye isetyenziswa ngokubanzi kwiirediyo ezahlukeneyo kunye nezixhobo zombane.I-resistor yefilimu yensimbi iboniswe kumzobo ongezantsi.
