Resistorsanoshandiswa zvakanyanya mumaseketi emagetsi, achiita basa rakakosha mukudzora kuyerera kwemagetsi. Kune marudzi akasiyana-siyana ezvipikisi pamusika, uye zvisinei nerudzi rwavo, ivo vese vane yavo chaiyo tembiricha coefficients, kureva kuti yese resistor inokonzerwa nekushisa. Muchikamu chino, tichaongorora pfungwa uye kukosha kweResistors tembiricha coefficients.

Chii chinonzi Temperature Coefficient of Resistor?
Iyo tembiricha coefficient yeanopikisa, inoratidzwa nechiratidzo α (alpha), inoratidza kuti kuramba kunoshanduka sei nekupisa. Inowanzo kutsanangurwa muzvikamu pamiriyoni padhigirii Celsius (ppm/°C). Kune miviri miviri mikuru yetembiricha coefficients: yakanaka uye yakaipa.
Positive Temperature Coefficient (PTC): Resistors ine yakanaka tembiricha coefficient inoratidza kuwedzera kwekupokana sezvo tembiricha inokwira. Aya maitiro akajairika mumidziyo iyo magetsi ekufambisa anovandudza nepamusoro tembiricha, senge mamwe simbi oxides.
Negative Temperature Coefficient (NTC): Mukupesana, zvinopikisa zvine tembiricha yakashata coefficient chiitiko kudzikira mukupokana sezvo tembiricha inowedzera. Izvi zvinowanzoonekwa mune semiconductors uye zvimwe zvinhu uko conductivity inoderera nekukwira kwekushisa.
Resistance Change Rate Kubva pane Tembiricha ( Muenzaniso)
Mumamiriro ezvinhu api anofanira kupisa coefficient aresistorkurangarirwa?
Kufunga nezve tembiricha coefficient ye resistor inowanzokosha mune anotevera mamiriro:
1. Mamiriro ekunze ane shanduko huru yekushisa: Kana dunhu kana chigadziriso chemagetsi chinoratidzwa nekushanduka kukuru kwekushisa panguva yekushanda, iyo tembiricha coefficient ye resistor inova yakakosha. Muchiitiko ichi, kusarudza resistor ine yakakodzera tembiricha coefficient inogona kuvimbisa kuti dunhu rinoramba rakagadzikana pane akasiyana tembiricha.
2. Precision maseketi: Mune mamwe maseketi anoda kurongeka kwakanyatso kupikisa, kunyanya mumashandisirwo akadai seyero, masensa, uye amplifiers echokwadi, tembiricha coefficient ye resistor inoda kutariswa. Precision maseketi kazhinji anoda kupa kwakaringana uye kugadzikana kubuda pamusoro petembiricha dzakasiyana.
3. Zvishandiso zveMaindasitiri: Mune mamwe maindasitiri ekushandisa, zvishandiso zvinogona kukanganiswa nepamusoro kana yakaderera tembiricha nharaunda. Muchiitiko ichi, iyo tembiricha coefficient ye resistor ndiyo yakakosha dhizaini parameter kuona kuti kuita kwedunhu hakukanganisike nekushanduka kwekushisa.
4. Tembiricha muripo: Mamwe maapplication anoda kushandiswa kweanopikisa muripo wetembiricha kuti ive nechokwadi chekushanda kwakajairika kwedunhu pasi pemamiriro ekushisa akasiyana. Muchiitiko ichi, zvinodikanwa kusarudza resistor ine yakakodzera tembiricha coefficient.
Kusarudzwa kwakakodzera kwevanopikisa kunovimbisa kugadzikana uye kubudirira kwemaitiro emagetsi. Mainjiniya nevagadziri vanofanirwa kunyatso ongorora tembiricha hunhu hwevanopikisa kuti vasangane nezvinodiwa zvekushandisa kwavo uye kugadzira akasimba uye akavimbika emagetsi mhinduro.
Paunenge uchisarudza chinopikisa, ruzivo rwekushisa coefficient ye resistor inowanzowanikwa mune yakatarwa pepa rakapihwa nemugadziri.
Shenzhen Zenithsun Electronics Tech. Co., Ltd inyanzviresistorsmugadziri, ane makore makumi maviri echiitiko, uye ane nyanzvi yeinjiniya timu yekubatsira vashandisi kusarudza izvo zvinopikisa.
