Salut,Pe o placa electronica ce inseamna U201, U202, U203?U201 = primul circuitU202 = al doilea circuitU203 = ...s.a.m.d??Multumesc

Sa zicem ca ai un aparat care pe o placa (sau mai multe) are diverse module (sa zicem preamplificator, amplificator, corector de ton, etc.). La modulul numarul 1 (preamplificator) notatia integratelor se face U101, U102... La modulul numarul 2 (corector) notatia se face U201, U202. Si tot asa. In acest fel se usureaza depanarea si citirea schemei, pe schema electronica se face referire la U201 (notat si pe placa U201) fiind mai usor decat codul in clar al piesei (LM741, sa zicem). Astfel stii exact despre ce piesa este vorba si pe ce modul il gasesti, mai ales daca sunt mai multe LM741 pe schema.
