eu ma gandeam la cate 2 sau chiar 3 mj-uri (15003 sau 15024) pe ramura pentru ceea ce vreau sa fac (200w/8 Ohmi) , mi se pare corect sa am si o marja de siguranta pt comportarea reactiva a boxelor

 

in modul in care vreau sa realizez schema , puterea disipata atinge varfuri de 225W pe ramura (in cel mai rau caz : 8 Ohmi + Omega 8 , adik defazaj de 45 grade in sarcina) , asta ar fi usor de suportat de mj-urile respective fara a necesita o racire fortata sau un radiator extrem de mare , plus .... fiabilitate prin scaderea temperaturii de functionare a finalilor .... in caz k se intreaba cineva ce e cu asta exista pe situ-l ON Semiconductor un calculator pt evaluarea aproximativa a fiabilitatii in functie de temperatura de functionare a tranzistorului
