El nou TAC per fer estudis coronaris de … Tīmeklis2024. gada 10. jūl. · Q1) Yes you can, if we assume the mounting base to be at 50°C, then using 4 W dissipation and 0.55 K/W (max value) thermal resistance of junction to base we get: Tj = 50°C + (4 W * 0.55 °C/W) = 52.2°C. Q2) Yes, the method of calculation is the same as above and the "starting point" will be the ambient …
