cum se imperecheaza tranzistorii?

Recommended Posts

vreau sa fac un ampliicator cu tranzistori bipolari si nu stiu cum se imperecheaza tranzistorii :(la cei mici,merg testati cu aparatul de masura,si ii aleg pe aceea cu un factor de amplificare cat mai apropiat,nu?dar la cei in capsula to3 sau to220 ce fac? ca in soclul ala nu incap :(banuiesc ca daca sunt din acelasi lot,au parametrii apropiati,dar daca sunt mai putin originali nu se stiema gandeam la 3 fire cu crocodili la capat,pt masurarea acestor tranzistori,dar poate aparatul de masura sa masoare factori de amplificvare asa de mici?si tranzistorii se imperecheaza doar dupa factorul de amplificare,sau mai exista si alt criteriu?astept sugestiims

Eu folosesc 3 fire cu cleme crocodil la capete ca sa masor Beta la trz cu capsule care nu incap in soclul aparatului de masura. Cele 3 fire poti sa le infigi in soclu sau sa le lipesti definitiv in interiorul aparatului.
