Kurwanyazikoreshwa cyane mumuzunguruko wa elegitoronike, zigira uruhare runini mugucunga imigendekere yumuriro wamashanyarazi. Hariho ubwoko butandukanye bwurwanya ku isoko, kandi tutitaye kubwoko bwabo, bose bafite coefficient yihariye yubushyuhe, bivuze ko buri résistoriste iterwa nubushyuhe. Muri iki kiganiro, tuzasesengura igitekerezo n'akamaro ka coefficient ya Resistors.
Ubwoko bwa ZENITHSUN
Coefficient ya Temperature ya Resistor ni iki?
Ubushyuhe bwubushyuhe bwa résistoriste, bwerekanwa nikimenyetso α (alpha), bugaragaza uburyo kurwanya bihinduka hamwe nubushyuhe. Ubusanzwe igaragara mubice kuri miriyoni kuri dogere selisiyusi (ppm / ° C). Hariho ubwoko bubiri bwingenzi bwubushyuhe: ibyiza nibibi.
Coefficient yubushyuhe bwiza (PTC): Kurwanya hamwe nubushuhe bwiza bwubushyuhe bugaragaza kwiyongera muburwanya uko ubushyuhe buzamuka. Iyi myitwarire isanzwe mubikoresho aho amashanyarazi atera imbere hamwe nubushyuhe bwo hejuru, nka okiside zimwe na zimwe.
Coefficient mbi yubushyuhe (NTC): Ibinyuranye, abarwanya ubukana bafite coeffisente yubushyuhe bubi bagabanuka mukurwanya uko ubushyuhe bwiyongera. Ibi bikunze kugaragara muri semiconductor hamwe nibindi bikoresho aho imiyoboro igabanuka hamwe nubushyuhe bwiyongera.
Igipimo cyo Guhindura Kurwanya Ukurikije Ubushyuhe (Urugero)
Ni ibihe bihe bigomba kuba coefficente yubushyuhe bwa arésistorgusuzumwa?
Urebye ubushyuhe bwubushyuhe bwa résistoriste ni ngombwa mubihe bikurikira:
1. Ibidukikije bifite ubushyuhe bunini: Niba umuzunguruko cyangwa igikoresho cya elegitoronike gihuye nihindagurika ryinshi ryubushyuhe mugihe gikora, coefficente yubushyuhe bwa résistor iba ingenzi. Muri iki gihe, guhitamo résistoriste hamwe nuburinganire bukwiye burashobora kwemeza ko umuzenguruko uguma uhagaze neza kubushyuhe butandukanye.
2 Inzira zuzuye zikenera gutanga umusaruro wuzuye kandi uhamye hejuru yubushyuhe butandukanye.
3. Inganda zikoreshwa mu nganda: Mubikorwa bimwe byinganda, ibikoresho birashobora guterwa nubushyuhe bwo hejuru cyangwa buke. Muri iki gihe, coefficente yubushyuhe bwa résistor ni ikintu cyingenzi cyerekana igishushanyo mbonera kugirango imikorere yumuzunguruko idaterwa nihindagurika ryubushyuhe.
4. Muri iki kibazo, birakenewe guhitamo résistoriste hamwe nuburinganire bukwiye.
Guhitamo neza kubarwanya byemeza ituze hamwe na sisitemu ya elegitoroniki. Ba injeniyeri n'abashushanya bagomba gusuzuma neza ubushyuhe buranga abarwanya kugirango bahuze ibyifuzo byabo kandi bashireho ibisubizo bikomeye kandi byizewe bya elegitoroniki.
Mugihe uhitamo résistoriste, amakuru yubushuhe bwubushuhe bwamakuru arashobora kuboneka mumpapuro zabugenewe zitangwa nuwabikoze.
Shenzhen Zenithsun Electronics Tech. Co, Ltd ni umunyamwugaabarwanyauwabikoze, afite uburambe bwimyaka 20, kandi afite itsinda ryubwubatsi bwumwuga kugirango rifashe abakoresha guhitamo neza.
