The Murata Production Institute of Corporation has successfully developed a multi-layer ceramic capacitor "GRM188D72A105KE01" for 48V lines in base stations, servers, and data centers, and has been put into mass production. This product is available at 1608M (1.6 × 0.8mm) size and rated voltage of 100V can achieve 1 μ F's super large electrostatic capacity (according to Murata survey data as of November 20, 2023). GRM188D72A105KE01 (0603 1uF 100V X7R 10%) This model uses high-temperature resistant material X7T, with a temperature environment of -55 ℃~125 ℃, and a durability testing environment of (125 ℃ rated voltage * 150% 1000 hours)。
With the development of 5G technology, it is expected that the demand for mobile traffic will sharply increase. The infrastructure of base stations needs to meet the requirements of miniaturization, lightweight, and low-power consumption to expand the coverage of 5G networks. In addition, although multiple output leads to an increase in the number of installed components, it requires the maintenance or even reduction of mechanical dimensions, making high-density circuit boards even more important.
This product applies the thin-layer technology independently developed by Murata. Compared to the 2012M size (GRM21BC72A105KE01) multilayer ceramic capacitor, it has achieved a volume reduction of about 67% and an area reduction of about 49%. This helps reduce circuit board space.
