World’s First 1 µF Capacitance 100 V Multilayer Ceramic Capacitor in a 1608M Size Commercialized

C A P A C I T O R

Murata Manufacturing Co., Ltd. (hereinafter, “Murata”) has developed and started mass producing the GRM188D72A105KE01 (hereinafter, “this product”), a 1608M (1.6 x 0.8mm) size multilayer ceramic capacitor with the world’s largest* capacitance of 1 µF and rated at 100 V for use in 48 V power supply lines in base stations, servers, and data centers. Samples are available.

*Murata findings as of November 20, 2023.

With the increasing adoption of 5G technology, mobile data traffic is projected to increase dramatically, requiring base station infrastructure to become smaller in size, more lightweight, and lower in power consumption in order to expand 5G network coverage. The number of circuit board components also continues to increase with the rise in multiple output power supply use, creating demand for device sizes to be maintained or made smaller and making it increasingly important for circuit boards to have higher component densities.

Murata’s proprietary thin layer technology has allowed for this product to be approximately 67% smaller in volume and 49% smaller in area than our 2012M size (GRM21BC72A105KE01) multilayer ceramic capacitors. This will allow the capacitor to take up less space on the circuit board.
