While the current product offering from 1 to 3 W is well known, there have been some significant developments and capability improvements. The SM Series is being designed into several new applications where a higher power rating in a smaller package is needed. The SM 3A is a low profile device with low resistance values. It is a 3 W rated part in the same package as the SM 2 A, which is a 2 W device. By improving the materials and using special processing, Stackpole is able to create devices that outperform most similar competitive devices. Stackpole has also begun development of a larger 4 W SMD device in an 8035 size package. With improvements in materials and a slightly larger body size, the SM 5 is also in development. Stackpole has the ability to change the characteristics of the SM series and any other wirewound product to suit any customer need; whether it is a fusing characteristic, high inductance, low inductance, non-inductive or higher power in smaller packages.
