In PI Expert and PI Xls, what is “maximum terminations per pin?
PI Expertand PIXls both use multifilar windings in the transformer design. This means that rather than use one thick wire it uses two or three (or more) parallel stands of thinner wire. As more and more parallel wires are used, it becomes difficult to terminate all these wires onto a single pin especially if the wires are thick and the pin is thin as is the case with small bobbins. In this case it is better to split the wires between 2 or 3 different pins for the terminations. The “maximum terminations per pin” specifies how many wires can be terminated onto a single pin and the default is set to 4 wires per pin. For thinner wires this number may be as high as 6 and for thicker wires this number may be as low as 2.
