Murata Power Solutions’ first generation of surface mount packages for the low-power, unregulated converters was realized in the 1 W NTE series. The NTE package remains popular and has been adopted by several competitors. This series has a footprint that occupies 1.42 cm2 of board space. The MTU1 series represents the second generation of 1 W surface mount solutions with its innovative package that boasts a 50% reduction in footprint over the NTE and comparable competitive products. Now, the newest NXE1 series of surface mount solutions occupies slightly less board space than the NTE series, but shares the NTE’s pin configuration and can drop onto a board laid out for the NTE. While it occupies more board area that the MTU series, the new NXE1 series offers a lower profile for applications with a height constraint. Compared to the 6.6 mm height of the NTE series, and the 8.5 mm height of the MTU models, the NXE1 series is just 4.8 mm tall, or nearly 30% shorter than the NTE, and 44% shorter than the MTU.
