Another important design feature is the wide termination style of the MCW 0612 AT Series (and that of the smaller case size MCW 0406 AT which is also available) which results in several unique product properties. In general, heat dissipation from the component to the ambient is dominated (about 80 %) by conduction into the PCB. Wide terminations decrease the thermal resistance of the assembly and thus allow for significantly increased power ratings. Besides extraordinary high power rating, the thermal cycling robustness of wide terminated parts can be enhanced. As the 0406 case size uses the same distance between its electrodes as the smaller case size 0402, the MCW 0406 AT also handles up to 3000 cycles of “Rapid Change of Temperature” from -40°C to +125°C. Accordingly, for the MCW 0612 AT a thermal cycling capability equivalent to case size 0603 is expected, namely 2000 cycles (* evaluation currently under progress).
