Features
- Compatible with 1000A or more
- Achieve high current with 2.0 mm or more thick copper
- Structure capable of high heat radiation (copper stack pin)
Development of a thick copper substrate compatible with high currents
Allowable current value calculation formula
-
I = kΔT0.44A0.725
I : Electric current (A)k : Constant (Outer layer : 0.048 Inner layer : 0.024)
ΔT : Temperature rise (°C)A : Conductor cross-sectional area (mil2)*1mil = 0.001 inch = 0.0254 mm
