Abaphikisiasetshenziswa kakhulu kumasekhethi kagesi, adlala indima ebalulekile ekulawuleni ukugeleza kwamandla kagesi. Kunezinhlobo ezahlukene zokuphikisa emakethe, futhi kungakhathaliseki uhlobo lwazo, zonke zinama-coefficients azo okushisa athile, okusho ukuthi yonke into ephikisayo ithonywa izinga lokushisa. Kulesi sihloko, sizohlola umqondo kanye nokubaluleka kwama-coefficients okushisa e-Resistors.

Iyini I-Temperature Coefficient of Resistor?

I-coefficient yezinga lokushisa ye-resistor, ekhonjiswa uphawu α (alpha), iveza ukuthi ukumelana kushintsha kanjani ngezinga lokushisa. Ngokuvamile kucaciswa izingxenye ngesigidi ngedigri Celsius (ppm/°C). Kunezinhlobo ezimbili eziyinhloko zama-coefficients okushisa: okuhle nokubi.

I-Positive Temperature Coefficient (PTC): Izinto eziphikisayo ezine-coefficient yezinga lokushisa elihle zibonisa ukwanda kokumelana njengoba izinga lokushisa likhuphuka. Lokhu kuziphatha kuvamile ezintweni lapho conductivity kagesi ithuthuka ngamazinga okushisa aphezulu, njengama-metal oxides athile.

I-Negative Temperature Coefficient (NTC): Ngokuphambene, izimbangi ezine-coefficient yezinga lokushisa engalungile zihlangabezana nokuncipha kokumelana njengoba izinga lokushisa likhuphuka. Lokhu kuvame ukubonwa kuma-semiconductors nezinye izinto lapho ukuhanjiswa kwehla ngokukhuphuka kwamazinga okushisa.

Kungaphansi kwaziphi izimo okufanele i-coefficient yezinga lokushisa aisiphikisakucatshangelwe?

Ukucabangela i-coefficient yezinga lokushisa le-resistor ngokuvamile kubalulekile kulezi zimo ezilandelayo:

1. Indawo enezinguquko ezinkulu zokushisa: Uma isekethe noma idivayisi ye-elekthronikhi ibhekene nokuguquguquka okukhulu kwezinga lokushisa ngesikhathi sokusebenza, i-coefficient yezinga lokushisa le-resistor iba ebalulekile. Kulesi simo, ukukhetha i-resistor ene-coefficient yokushisa efanelekile kungaqinisekisa ukuthi isifunda sihlala sizinzile phezu kwamazinga okushisa ahlukene.

2. Amasekhethi anembayo: Kwamanye amasekhethi adinga amanani okumelana anembe kakhulu, ikakhulukazi ezinhlelweni zokusebenza ezifana nokulinganisa, izinzwa, nama-amplifiers anembile, i-coefficient yezinga lokushisa ye-resistor idinga ukucatshangelwa. Amasekhethi anembayo ngokuvamile adinga ukunikeza okukhiphayo okunembile nokuzinzile ngaphezu kwamazinga okushisa ahlukene.

3. Izicelo Zezimboni: Kwezinye izinhlelo zokusebenza zezimboni, izinto zokusebenza zingathintwa indawo yokushisa ephezulu noma ephansi. Kulesi simo, i-coefficient yokushisa ye-resistor iyipharamitha yokuklama ebalulekile ukuqinisekisa ukuthi ukusebenza kwesifunda akuthintwa ukushintsha kwezinga lokushisa.

4. Isinxephezelo sezinga lokushisa: Ezinye izinhlelo zokusebenza zidinga ukusetshenziswa kokumelana nesinxephezelo sokushisa ukuze kuqinisekiswe ukusebenza okuvamile kwesekethe ngaphansi kwezimo ezihlukene zokushisa. Kulokhu, kuyadingeka ukukhetha i-resistor ene-coefficient yokushisa efanelekile.

Ukukhethwa okufanele kwama-resistors kuqinisekisa ukuzinza nokusebenza kahle kwezinhlelo ze-elekthronikhi. Onjiniyela nabaklami kufanele bahlole ngokucophelela izici zokushisa zezibambiso ukuze bahlangabezane nezimfuneko ezithile zezinhlelo zabo zokusebenza futhi bakhe izixazululo eziqinile nezithembekile ze-elekthronikhi.

Uma ukhetha ukumelana, ulwazi lwe-coefficient yezinga lokushisa le-resistor ngokuvamile lungatholakala eshidini lemininingwane elinikezwe umenzi.

I-Shenzhen Zenithsun Electronics Tech. I-Co., Ltd inguchwephesheresistorsumkhiqizi, unesipiliyoni seminyaka engu-20, futhi unethimba lonjiniyela elichwepheshile elisiza abasebenzisi ukukhetha izimbangi ezifanele.
