crydel Posted March 29, 2010 Share Posted March 29, 2010 Acum 2 zile am primit niste cdb uri la care nu am gasit nici un fel de datasheet cu goagalul si altele care habar nu am ce sunt sau ce fac ,rog daca aveti geva info sa-mi spuneti si mie cdb430e cdb410e cdb408e cdb409em(punct galben) cdb490e A723C BCII32 BCII33 BCII31 B7417 Robeert: vezi ca ti-am modificat titlul. Ar fi trebuit inchis topicul, dar hai... Link to comment
Mikrosha Posted March 29, 2010 Share Posted March 29, 2010 CDB-uri sunt circuite digitale in tehnologie bipolara, adica TTL. CDB4xx = SN74xx, adica: cdb430=SN7430, cdb410=SN7410 cdb408=SN7408, etc. Literele EM nu mai stiu ce relevanta au. A723 este LM723, stabilizator. BCII: B este Beta, indica fabricatie IPRS Baneasa. CII sunt tot niste coduri pentru CDB-uri: CII31 = CDB541 = SN7451 CII32=CDB440 = SN7440 CII33=CDB430 = SN7430. Cauta-le pe http://www.datasheetcatalog.com. К165ГФ3 din prima poza e ceva generator de impulsuri, nu stiu daca are echivalent. In a doua poza sunt niste transformatoare pe ferita, probabil pentru choppere miniaturizate. (ex. calculatoare cu VFD, etc) Link to comment

rimache Posted March 30, 2010 Share Posted March 30, 2010 Literele EM nu mai stiu ce relevanta au. E - capsula "dual-in-line"M- temperatura de lucru -55...+125 grade C Link to comment
