K-AVX Unveils MLCC Delivering Industry-Highest 47μF Capacitance in 0402 Case Size

K-AVX has successfully developed the world’s first compact, high-capacity multilayer ceramic chip capacitor (MLCC) with an industry-leading capacitance value of 47µF in the 0402-inch size (1.0mm x 0.5mm). Mass production scheduled to start in December 2025.

Why is high capacitance required in a small case size?

The rapid evolution of artificial intelligence (AI) technology is driving a surge in demand for smartphones equipped with generative AI and AI servers. Additionally, as data processing technology becomes more advanced, the number of integrated components is increasing. Consequently, there is a growing need for ultra-compact components that allow for efficient component mounting within limited board space.

In the case of MLCCs, which are extensively used in these electronic devices, there is a strong expectation for further miniaturisation and increased capacitance. At the same time, there is a demand for high reliability in components used in harsh temperature environments due to heat generation and other factors.

K-AVX KGM05 Series

The ‘0402-inch size’ MLCC developed by K-AVX is the most widely adopted size for smartphones and wearable devices. Through K-AVX’s unique material and process technologies, they have achieved further thinning of the dielectric and internal electrodes, successfully expanding the capacitance per unit by approximately 2.1 times compared to our previous product (22μF) of the same size.

This contributes significantly to securing the necessary capacitance and reducing the number of components. Moreover, high heat resistance up to +105°C ensures high reliability in harsh temperature environments, such as AI servers.
