Murata Develops World's Smallest Chip Inductor - 008004 size (0.25 x 0.125 mm)
Murata Manufacturing Co., Ltd. has developed the world's smallest 008004 -size (0.25 x 0.125 mm) chip inductor.* The volume of this new chip inductor is approximately 25% of the 01005 size (0.4 x 0.2 mm), the predominant chip inductor presently used in market-leading smartphones.
Background of Commercialization
The number of electronic components used in compact mobile devices such as smartphones continues to increase enabling multi-band capability and an increasingly larger number of advanced features. This is driving a growing need for ultra-small components that can support high-density mounting. 01005-size high-frequency chip inductors, which had been the smallest size commercialized to date, have seen increasingly widespread adoption, especially for use in high-frequency modules. However, Murata has mobilized its own cutting-edge micromachining technology to become the first company globally to produce prototypes of 008004 -size chip inductors, which are the world's smallest. Development is currently proceeding with plans to start shipping samples before the end of fiscal 2014.

Together with capacitors and resistors, they are basic components in electronic circuits, and are also known as coils. In terms of their main applications, they can be divided into two categories: signal-type inductors and power supply-type inductors. "High-frequency inductors" belong to the signal-type category and are used especially in high-frequency circuits, for example. In circuits that convey electrical signals, they are mainly used for impedance matching and as filters. Power supply-type inductors play noise suppression, smoothing and other roles in circuits that supply power to semiconductors.
