Pakati pe zvigadzirwa zvemagetsi zvakaongororwa mune ino blog pane atove akati wandei marudzi ema transistors, ese bipolar uye munda mhedzisiro. Ino ndiyo nguva yekuwedzera imwe kuchinyorwa, sezvazviri iyo 2n3904, inova imwe yeanonyanya kushandiswa muhuwandu hwemagetsi emagetsi. Mune ino kesi iri imwe BJT, kana bipolar, asi iine mamwe maitiro anonakidza aunofanira kuziva.
Pano iwe uchazoziva kuti chaizvo chii, pinout yayo, kupi kwekuwana madhata emidziyo, sei kutenga imwe yadzo, uye yakareba etc.
Chii chinonzi transistor 2n3904?
El 2N3904 transistor Iyo mhando ye bipolar transistor, BJT mhando yechiratidzo chidiki (yakaderera simba uye yakaderera simba, iine epakati voltages). Rudzi rwe transistor iyi NPN, uye ine zvimwe zvinonakidza hunhu, sekumhanyisa switching (inogona kushanda nemhando yepamusoro), yakadzika yekuzadza magetsi, uye inokodzera kutaurirana nekusimudzira.
Unogona kuona mukati zvigadzirwa zvemazuva ese senge materevhizheni, mawairesi, vhidhiyo kana ekuridza odhiyo, mawartz equartz, mwenje we fluorescent, nhare, nezvimwe.
Iyi transistor chishandiso yakajairika. Zvanga zviri bvumidzwa ne Motorola Semiconductor muma60s, pamwe nePNP 2N3906 (shamwari yayo). Kutenda kwaari, kugona kwakawedzerwa. Uyezve, yakachipa, ine TO-92 package nhasi, sekutsiva yako yekare simbi package.
Kana zvakadaro mbambo yako, iwe unogona kuzviona mumufananidzo wekare, kuti sezvazvinowanzoitika mumashandisirwo, une mapini matatu akaverengerwa achisiya chikamu chakatenderedzwa chepakeji akananga kumashure, ndiko kuti, kududzira dhizaini uye kuenderana neyawakabata muruoko ikozvino , unofanirwa kuisa chikamu chakadzika pamberi pako.

Kwokutenga 2N3904
Para tenga transistor Pakati pehunhu uhwu, unogona kushandisa akasiyana masevhisi ezvitoro zvine hunyanzvi mumagetsi, kana mumapuratifomu akadai seAmazon. Semuenzaniso, heano mamwe mazano:
- Bojack bhegi rine 250 zvidimbu. Transistors emhando dzakawanda, pakati payo pane 2n3904.
- Hapana zvigadzirwa zvakawanikwa. Iyo zvakare ine iyi pack yemakumi mashanu emayuniti e50n2.
- TooGoo Iyo zvakare inopa imwe kurongedza zvishoma yakachipa uye ine makumi maviri nemaviri mayuniti e25n2.
