- 60 percent less volume and smaller footprint than existing products
- Very high current capability of 500 mA in a miniature 1005 size power inductor
Jul. 9, 2013
TDK Corporation has expanded its MLP series of multilayer power inductors with the new MLP1005M1R0D in case size IEC 1005. The new component measures in at a miniature 1.0 mm x 0.5 mm x 0.7 mm and is thus the world's smallest multilayer power inductor*. Both the footprint and the volume of the newly developed inductor are about 60 percent smaller than existing products with dimensions of 1.6 mm x 0.8 mm x 0.8 mm. The miniaturized multilayer power inductor offers a rated inductance of 1.0 µH and a rated current of 500 mA. The product is designed for use in the power supply circuits of smartphones, tablet PCs, digital cameras, and other mobile devices. Mass production begins in July 2013.
Thanks to TDK’s advanced structural design and materials technologies, the MLP1005M1R0D employs a particularly low-loss ferrite material. As a result, the new multilayer power inductor features electrical characteristics that allow its application in power supply circuits rated for up to 500 mA, which is very high for a 1005 size inductor.
The need for power inductors in mobile devices is growing rapidly. These devices are often used continuously in modes that involve large-volume, high-speed communications, leading to higher power consumption. Moreover, the trend toward multi-functionality requires multiple power supply configurations with a higher number of inductors. As a result, battery life and space restrictions on power supply circuits are becoming increasingly challenging design issues. The new MLP1005M1R0D provides advantages on both fronts, enabling smaller dimensions and higher power supply efficiency.
With the addition of the new type, TDK’s very broad lineup of multilayer power inductors now covers high-performance components in case sizes from 2520 (2.5 mm x 2.0 mm) to 1005, including case sizes 2016 ( 2.0 mm x 1.6 mm), 2012 ( 2.0 mm x 1.2 mm), and 1608 (1.6 mm x 0.8 mm) with rated currents up to 2300 mA and rated inductances up to 10 µH.
