Abaxhathisizisetyenziswa kakhulu kwiisekethe zombane, zidlala indima ebalulekileyo ekulawuleni ukuhamba kombane. Kukho iintlobo ezahlukeneyo ze-resistors kwimarike, kwaye kungakhathaliseki ukuba luhlobo luni na, zonke zinee-coefficients zazo zokushisa ezikhethekileyo, oko kukuthi yonke into echasayo iphenjelelwa bubushushu. Kweli nqaku, siza kuphonononga ingcamango kunye nokubaluleka kwee-coefficients zokushisa kwe-Resistors.
ZENITHSUN eziphambili Iintlobo Resistors
Yintoni iTemperature Coefficient of Resistor?
I-coefficient yeqondo lokushisa le-resistor, echazwe ngesimboli α (alpha), ichaza indlela ukuchasana kutshintsha ngayo ubushushu. Ngokuqhelekileyo ichazwa ngamalungu kwisigidi ngeqondo lokukaCelsius (ppm/°C). Kukho iintlobo ezimbini eziphambili ze-coefficients zokushisa: ezilungileyo kunye nebi.
I-Positive Temperature Coefficient (PTC): I-Resistors ene-coefficient yokushisa efanelekileyo ibonisa ukwanda kokumelana njengoko ubushushu buphakama. Oku kuziphatha kuqhelekile kwizinto apho ukuhanjiswa kombane kuphucula ngamaqondo okushisa aphezulu, njengee-oxide zetsimbi ezithile.
I-Negative Temperature Coefficient (NTC): Ngokuchaseneyo, i-resistors ene-coefficient yeqondo lokushisa elibi namava ayancipha ukuchasana njengoko ubushushu bukhula. Oku kudla ngokubonwa kwii-semiconductors kunye nezinye izinto apho i-conductivity iyancipha ngokunyuka kwamaqondo okushisa.

Ngaphantsi kweziphi iimeko kufuneka i-coefficient yokushisa aisixhasikuqwalaselwa?
Ukuqwalasela i-coefficient yobushushu be-resistor ngokuqhelekileyo ibalulekile kwiimeko ezilandelayo:
1. Iindawo ezingqongileyo ezinokutshintsha okukhulu kweqondo lokushisa: Ukuba isiphaluka okanye isixhobo sombane sibonakaliswe kwiinguqu ezinkulu zeqondo lokushisa ngexesha lokusebenza, i-coefficient yokushisa ye-resistor iba yinto ebalulekileyo. Kule meko, ukukhetha i-resistor kunye ne-coefficient yokushisa efanelekileyo kunokuqinisekisa ukuba isiphaluka sihlala sizinzile kumaqondo okushisa ahlukeneyo.
2. Iisekethe ezichanekileyo: Kwezinye iisekethe ezifuna amaxabiso okumelana ngokuchanekileyo, ngakumbi kwizicelo ezifana nokulinganisa, i-sensor, kunye ne-amplifiers echanekileyo, i-coefficient yokushisa ye-resistor kufuneka ithathelwe ingqalelo. Iisekethe ezichanekileyo zihlala zifuna ukunika iziphumo ezichanekileyo nezizinzileyo kumaqondo obushushu ahlukeneyo.
3. Izicelo zoShishino: Kwezinye izicelo zemizi-mveliso, izixhobo zinokuchaphazeleka bubushushu obuphezulu okanye obuphantsi. Kule meko, i-coefficient yokushisa ye-resistor yi-parameter yoyilo olubalulekileyo ukuqinisekisa ukuba ukusebenza kwesiphaluka akuchaphazeli utshintsho lweqondo lokushisa.
4. Imbuyekezo yobushushu: Ezinye izicelo zifuna ukusetyenziswa kwe-resistors kwimbuyekezo yeqondo lokushisa ukuqinisekisa ukusebenza okuqhelekileyo kwesekethe phantsi kweemeko ezahlukeneyo zokushisa. Kule meko, kuyimfuneko ukukhetha i-resistor ene-coefficient yokushisa efanelekileyo.
Ukhetho olufanelekileyo lwabaxhathisi luqinisekisa ukuzinza kunye nokusebenza kweenkqubo zombane. Iinjineli kunye nabaqulunqi kufuneka bavavanye ngononophelo iimpawu zobushushu bezinto ezixhathisayo ukuhlangabezana neemfuno ezithile zezicelo zabo kunye nokudala izisombululo ezomeleleyo nezithembekileyo ze-elektroniki.
Xa ukhetha i-resistor, ulwazi lwe-coefficient yokushisa ye-resistor lunokufumaneka kwiphepha lenkcazo enikezelwe ngumenzi.
Shenzhen Zenithsun Electronics Tech. Co., Ltd yingcaliresistorsumenzi, uneminyaka engama-20 yamava, kwaye uneqela lobunjineli lobuchwephesha ukunceda abasebenzisi ukukhetha abachasi abachanekileyo.
