Power Inductors for Wearables are 60% Smaller

Taiyo Yuden Co., Ltd. has announced the expansion of its line-up of the MCOIL™ MC series of metal multilayer chip power inductors, which uses a metallic magnetic material, as well as the commercialization of the world's smallest metal power inductor MCEE1005 (1.0 x 0.5 x 0.55mm, maximum height).

This power inductor is designed for uses as a power choke coil in power supply circuits for wearable devices, smartphones, and IoT devices.

Based on advanced material and multilayer construction techniques, this 1005-size metal power inductor, achieves a volume that is over 60% smaller than the previous-generation product, the MCFK1608 (1.6 x 0.8 x 0.6 mm), and will contribute to developing smaller and thinner mobile devices such as wearable devices.

Today's market for smartwatches, wristband-type wearable devices, and IoT devices like sensor network devices requires not only reduced size and thickness but also highly efficient power supply circuits for longer operating time. While smartphones are getting thinner, they use higher-speed processors for higher performance and multi-core processors for higher efficiency.

Since high-speed multi-core processors, which are driven by lower voltage and larger current, use appropriate cores in accordance with processor load, each core is equipped with a dedicated power supply circuit, which requires small and thin power inductors with a large current capacity.

To address this market need, Taiyo Yuden has commercialized its metal multilayer chip power inductor MCOIL™ MC series, which uses a metallic magnetic material with high dc bias characteristics and has the advantage of being small and thin.
