Ukuphikiswa okunembile kuyinto ebaluleke kakhulu kumadivayisi we-elekthronikhi, ikakhulukazi lapho ukunemba okuphezulu kubalulekile.Kabanzi, bahlukaniswa ngezinhlobo ezintathu: Abamelana bama-Metal Film, ukumelana nabayintambo, kanye nokuvinjwa okuvinjelwe, ngalinye linezimpawu ezihlukile kanye nezicelo.
1. I-Metal Film Resistor
Ukumelana kwe-Metal Film, uhlobo oluvame kakhulu lokuphikiswa okunembile, ukuqhosha coeffleeflicent encane yokushisa.Lokhu kusho ukuthi bagcina amanani wokumelana ezinzile naphezu kokuhlukahluka kokushisa, okwenza balungele imishini ye-elekthronikhi ephezulu.Kodwa-ke, ukuba sengozini yabo kulele kwingxenye yefilimu, kuthambekele ekulimaleni ngesikhathi sokusika ezinopheyiselweni kanye nezinqubo zokuqothuka.
2. I-Wirewond Resistor
Ukumelana ne-WirewondandBasebenzisa izinhlobo ezintathu eziphambili zokumelana nezinto zokwakha:
- IConstantan: Indabuko, ngokuvimbela ukushisa okuncomekayo.Phansi kwayo?Ukushisa okungaphansi kokungaphansi kwe-electromocial ye-electromotive ephakeme okuphezulu kwamandla we-electromotive aphezulu aphezulu ethusi, okungenzeka kube nomthelela ngokunemba.
- I-Manganese Copper: Ukukhetha okuthandwayo kokulinganisa kwayo okuncane okulinganiselwe kanye namandla aphansi we-electromotive we-electromotive kunethusi, naphezu kokuphikiswa okuphansi okuphansi uma kuqhathaniswa noConstantan.
- U-Evanohm: Kuhlanganisa i-nickel-chromium-aluminium-Copper alloy, inezinqumo ezincane kakhulu zokushisa.Kodwa-ke, ubulukhuni balo bubeka izinselelo e-welding.
3. Vimba Ukumelana
Vimba abaphikisayo, noma ukumelana kwensimbi, faka i-alloy yokumelana ne-alloy elandelwe i-ceramic substrate.Imikhiqizo efana neVishay ihola lesi sigaba, isebenzisa ama-alloys we-nickel-chromium ama-alloys kanye nezindawo zokuhlobisa isinxephezelo sokushisa.Lokhu kufezekisa ama-coefficients aphansi okushisa, kwesinye isikhathi ngaphansi kwe-1ppm / ℃.Emkhakheni wasekhaya, amamodeli afana no-RJ711, noma athuthukile, asathola i-niche yawo emakethe yendawo.
