Smallest 1 Microfarad MLCC Claimed By Murata


Murata contributes to the continuing miniaturization and sophistication of mobile electronics by claiming the world’s first 05025M size (0.5 × 0.25 × 0.25 mm) monolithic ceramic capacitor (MLCC) with a capacitance value of 1 μF (X5R characteristics, 6.3 V rated voltage) in the world’s smallest component volume. Applications include decoupling of mobile electronics (smartphones, tablets, notebooks), wearable devices, and related modules.

“The smallest product with a capacitance value of 1 μF (X5R characteristics, 6.3V rated voltage) used to be the 0603M size (0.6 × 0.3 mm). The 05025M size (0.5 × 0.25 mm) cuts the component volume ratio by approximately half, achieving the world’s smallest component volume for a monolithic ceramic capacitor of the same characteristics.”

Operating temperature range for the capacitor is specified from -55 to 85℃. The capacitor complies to the 1 X5R characteristic which refers to a temperature characteristic in which the capacitance change rate is ±15% when the operating temperature range is -55°C to 85°C.

Featuring an aspect ratio of 2:1, the capacitor enables high-density mounting on the substrate. An aspect ratio of 2:1 is most efficient when components are arranged lengthwise and crosswise on the substrate. This ratio enables high production efficiency in the manufacturing process, stable supply and future cost reductions.


The capacitor has started mass production. For further details, view the full Press release.
