Dab tsi yog qhov sib txawv ntawm NTC thermistor chips nrog kub electrodes thiab nyiaj electrodes, thiab lawv cov ntawv thov kev lag luam txawv li cas?

NTC (Negative Temperature Coefficient) thermistor chips nrog kub electrodes thiab nyiaj electrodes muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm thiab kev lag luam kev lag luam, feem ntau vim yog lub cev thiab tshuaj lom neeg ntawm cov khoom siv electrode. Hauv qab no yog cov ncauj lus kom ntxaws sib piv:

I. Kev ua tau zoo sib txawv

1. Kev coj ua thiab kev tiv thaiv kev sib cuag

• Kub Electrodes:
  • Zoo conductivity, txawm tias me ntsis qis dua nyiaj (kub kub: ~ 2.44 μΩ·cm vs. nyiaj: ~ 1.59 μΩ·cm).
  • Ntau ruaj khov tiv thaiv vim kub tsis kam mus rau oxidation, kom ntseeg tau tias tsawg kawg kuj tsis dhau lub sij hawm.
• Silver Electrodes:
  • Superior conductivity, tab sis nws yooj yim rau deg oxidation (tshwj xeeb tshaj yog nyob rau hauv high-kub los yog humid ib puag ncig), ua rau muaj zog tiv thaiv thiab teeb liab instability.

2. Oxidation thiab Corrosion Resistance

• Kub Electrodes:
  • Tsis tshua muaj tshuaj lom neeg ruaj khov; resistant rau oxidation thiab corrosion (xws li, acids, alkalis), zoo tagnrho rau hnyav ib puag ncig (high humidity, corrosive gases).
• Silver Electrodes:
  • Reacts nrog sulfur thiab oxygen los tsim nyiaj sulfide / oxide, degrading kev ua tau zoo nyob rau lub sij hawm thaum raug huab cua.

3. Kev ruaj ntseg kub

• Kub Electrodes:
  • Kev ruaj ntseg kub kub zoo heev (nrog rau> 150 ° C), haum rau kev lag luam lossis kev siv tsheb (xws li, cav compartments).
• Silver Electrodes:
  • Oxidation accelerates ntawm qhov kub thiab txias; Feem ntau txwv rau ≤100 ° C yam tsis muaj kev tiv thaiv ntim.

4. Solderability

• Kub Electrodes:
  • Tau tshaj cov solders (xws li, tin paste), kom ntseeg tau tias muaj kev ruaj ntseg soldering rau automated SMT txheej txheem.
• Silver Electrodes:
  • Yuav tsum tau tiv thaiv oxidation solder los yog nitrogen-tiv thaiv soldering los tiv thaiv oxidation-induced defects (xws li, txias pob qij txha).

5. Lub neej ntev thiab kev ntseeg tau

• Kub Electrodes:
  • Lub neej ntev, zoo tagnrho rau cov ntawv thov kev ntseeg siab (xws li, cov khoom siv kho mob, aerospace).
• Silver Electrodes:
  • Lub neej luv dua tab sis txaus rau qhov chaw me me (piv txwv li, cov khoom siv hauv tsev).

      

II. Kev ua lag luam sib txawv

1. Kub Electrode Chips

• High-End Industrial & Automotive Electronics:
  • Cav tswj units (ECU), roj teeb tswj systems (BMS), muaj sensors nyob rau hauv high-kub / vibration ib puag ncig.
• Cov cuab yeej kho mob:
  • Kev ntsuas kub hauv kev kho mob, saib xyuas tus neeg mob (yuav tsum tau biocompatibility thiab stability).
• Aerospace & Kws muaj txuj ci:
  • Kev ntsuas kub hauv cov xwm txheej huab cua (kua hluav taws xob, thermal cycling ceev).
• Cov cuab yeej Precision:
  • Cov khoom siv hauv chav kuaj, qhov tseeb siab thermal tswj tshuab.

2. Nyiaj Electrode Chips

• Consumer Electronics:
  • Roj teeb kub tiv thaiv hauv smartphones, laptops (nqi-sensitive, ib puag ncig me me).
• Cov Khoom Siv Hauv Tsev:
  • Kev tswj qhov kub thiab txias hauv cov cua txias, tub yees, lub tshuab cua sov.
• Teeb pom kev zoo & LED:
  • Kev tiv thaiv overheat nyob rau hauv cov nqi-sensitive teeb pom kev zoo.
• Low-End Industrial Equipment:
  • Ib puag ncig tsis xav tau (piv txwv li, lub cev muaj zog me, lub zog hloov hluav taws xob).

III. Nqi thiab Supply Chain Considerations

• Kub Electrodes:Cov khoom siv siab (kub yog ~ 70-80 × pricier dua nyiaj), tab sis cov txheej txheem ruaj khov thiab cov txiaj ntsig siab pom zoo rau lawv siv hauv cov ntawv ntim qis, muaj txiaj ntsig zoo.
• Silver Electrodes:Cov khoom siv qis dua, tsim nyog rau kev tsim khoom loj, tab sis yuav xav tau cov txheej txheem tiv thaiv oxidation (xws li, npib tsib xee plating), ntxiv kev tsim khoom nyuaj.

IV. Cov ntsiab lus thiab cov lus pom zoo

• Xaiv Kub Electrodesrau: Kub-kub, corrosive, los yog kev ntseeg siab-tseem ceeb daim ntaub ntawv (automotive, kho mob, aerospace).
• Xaiv Silver Electrodesrau: Nqi-sensitive, me me-ib puag ncig daim ntawv thov nrog ib tug nruab nrab lifespan yuav tsum (cov khoom siv hluav taws xob, khoom siv).

Los ntawm kev ntsuas qhov kev xav tau ntawm kev ua tau zoo, ib puag ncig, thiab kev txwv nyiaj txiag, hom electrode zoo tuaj yeem xaiv rau koj daim ntawv thov.
