NTC golide ndi siliva electrode chip ntchito ndi kuyerekezera ntchito

Kodi pali kusiyana kotani pakati pa tchipisi ta NTC thermistor yokhala ndi maelekitirodi agolide ndi maelekitirodi asiliva, ndipo ntchito zawo zamsika zimasiyana bwanji?

NTC (Negative Temperature Coefficient) ma thermistor tchipisi okhala ndi maelekitirodi agolide ndi maelekitirodi asiliva amawonetsa kusiyana kwakukulu pamagwiridwe ndi kagwiritsidwe ntchito ka msika, makamaka chifukwa chachilengedwe komanso mankhwala azinthu zamagetsi. Pansipa pali kuwunika kofananiza mwatsatanetsatane:

I. Kusiyana kwa Kachitidwe

1. Conductivity ndi Contact Resistance

• Gold Electrodes:
  • Mayendedwe abwino, ngakhale otsika pang'ono kuposa siliva (kukana kwa golide: ~2.44 μΩ·cm vs. siliva: ~1.59 μΩ·cm).
  • Kukhazikika kokhazikika kolumikizana chifukwa cha kukana kwa golide ku oxidation, kuwonetsetsa kuti kukana kumayenda pang'onopang'ono pakapita nthawi.
• Silver Electrodes:
  • Kuwongolera kwapamwamba, koma kumakonda kukhala ndi okosijeni pamtunda (makamaka m'malo otentha kwambiri kapena onyowa), zomwe zimapangitsa kuti pakhale kukana kukhudzana ndi kusakhazikika kwazizindikiro.

2. Oxidation ndi Corrosion Resistance

• Gold Electrodes:
  • Chokhazikika kwambiri pamankhwala; kugonjetsedwa ndi makutidwe ndi okosijeni ndi dzimbiri (monga ma asidi, alkalis), yabwino kumadera ovuta (chinyezi chachikulu, mpweya wowononga).
• Silver Electrodes:
  • Imasanganikirana ndi sulfure ndi okosijeni kupanga silver sulfide/oxide, kuonongeka pakapita nthawi ikakhala pamlengalenga.

3. Kukhazikika kwa Kutentha

• Gold Electrodes:
  • Kukhazikika kwapamwamba kwambiri kwa kutentha (kupirira> 150 ° C), koyenera kumafakitale kapena magalimoto (mwachitsanzo, zipinda za injini).
• Silver Electrodes:
  • Oxidation imathandizira pa kutentha kwakukulu; nthawi zambiri amangokhala ≤100 ° C popanda kuyika zoteteza.

4. Solderability

• Gold Electrodes:
  • Imagwirizana ndi ma solders wamba (mwachitsanzo, phala la malata), kuwonetsetsa kuti ma soldering odalirika pamachitidwe a SMT.
• Silver Electrodes:
  • Pamafunika anti-oxidation solder kapena nitrogen-protected soldering kuti mupewe zolakwika zobwera chifukwa cha okosijeni (mwachitsanzo, mafupa ozizira).

5. Moyo wonse ndi Kudalirika

• Gold Electrodes:
  • Kutalika kwa moyo wautali, koyenera pamapulogalamu odalirika kwambiri (mwachitsanzo, zida zamankhwala, zakuthambo).
• Silver Electrodes:
  • Kutalika kwa moyo waufupi koma wokwanira kumalo ocheperako (mwachitsanzo, zida zapakhomo).

      

II. Kusiyana kwa Kugwiritsa Ntchito Msika

1. Gold Electrode Chips

• Zamagetsi Zapamwamba Zamakampani & Zagalimoto:
  • Magawo owongolera injini (ECU), makina owongolera ma batri (BMS), masensa am'mafakitale m'malo otentha kwambiri / kugwedera.
• Zida Zachipatala:
  • Kuwunika kwa kutentha mu kujambula kwachipatala, oyang'anira odwala (kufuna biocompatibility ndi kukhazikika).
• Zamlengalenga & Chitetezo:
  • Kuzindikira kutentha muzochitika zovuta kwambiri (ma radiation, kuthamanga kwapang'onopang'ono).
• Zida Zolondola:
  • Zida za labotale, machitidwe owongolera matenthedwe apamwamba kwambiri.

2. Silver Electrode Chips

• Consumer Electronics:
  • Chitetezo cha kutentha kwa batri mu mafoni a m'manja, ma laputopu (osakwera mtengo, malo ocheperako).
• Zida Zanyumba:
  • Kuwotcha kutentha mu air conditioners, firiji, zotenthetsera madzi.
• Kuwala & LED:
  • Kutetezedwa kwa kutentha kwambiri m'makina owunikira otsika mtengo.
• Zida Zamakampani Zotsika:
  • Malo osafunikira (mwachitsanzo, ma mota ang'onoang'ono, ma adapter magetsi).

III. Kuganizira za Mtengo ndi Katundu

• Gold Electrodes:Mtengo wamtengo wapatali (golide ndi ~ 70-80 × pricier kuposa siliva), koma njira zokhazikika ndi zokolola zambiri zimatsimikizira kugwiritsidwa ntchito kwawo muzogwiritsira ntchito zochepa, zamtengo wapatali.
• Silver Electrodes:Kutsika mtengo kwazinthu, koyenera kupanga zambiri, koma kungafunike zokutira zotsutsana ndi okosijeni (mwachitsanzo, kupaka faifi tambala), kuonjezera kupanga zovuta.

IV. Chidule ndi Malangizo

• Sankhani Gold Electrodeskwa: Kutentha kwambiri, kuwononga, kapena kudalirika kofunikira (zagalimoto, zamankhwala, zakuthambo).
• Sankhani Silver Electrodeskwa: Mapulogalamu osakwera mtengo, ocheperako okhala ndi zofunikira pa moyo wapakatikati (zamagetsi ogula, zida zamagetsi).

Mwa kulinganiza zosowa za magwiridwe antchito, momwe chilengedwe, komanso zovuta za bajeti, mtundu woyenera wa electrode ukhoza kusankhidwa kuti mugwiritse ntchito.
