Current carrying capacity of a via
WebOct 11, 2024 · termines the current carrying capacity of the trace--cross sectional area and environment. Looking first at the cross sectional areas, they are equal for both the via and the trace when: W1*T1 = p*(D2+T2)*T2 Using a little algebra, it can be shown that the cross sectional area of the trace and the cross sectional area of the via are equal when: WebInternal traces : I = 0.024 x dT0.44 x A0.725. External traces: I = 0.048 x dT0.44 x A0.725. Where I is maximum current in Amps, k is a constant, dT is temperature rise above ambient in °C, & A is cross sectional area of trace mils². The trace width can then be calculated by re-arranging this formula to determine the cross-sectional area that ...
