The MCEE1005 is part of the metal multilayer chip power inductor MCOI MC series, which uses a metallic magnetic material with a high DC bias characteristic for the smaller size. It is used as a power choke coil in power supply circuits for wearable devices, smartphones, and devices used in the Internet of Things (IoT). The inductor is over 60% smaller than the previous device, the MCFK1608 (1.6 x 0.8 x 0.6 mm).
Current smartwatch, wristband-type wearable devices and IoT designs such as 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. Each core in a high-speed multi-core processor will be driven by its own dedicated power supply circuit, which requires these small and thin power inductors with a large current capacity.
Production has started at subsidiary Wakayama Taiyo Tuden in Japan’s Wakayama prefecture at a rate of 10 million units per month.
