GRM1552C1H390JA01D

The GRM1552C1H390JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This part belongs to Murata's GRM series, which is widely recognized in industrial and consumer electronics applications for delivering reliable performance across demanding environments. Multilayer ceramic capacitors are fundamental passive components used to store electrical charge and manage signal integrity in electronic circuits. They serve critical functions including power supply filtering, decoupling, coupling, and noise suppression across a broad range of frequencies. The GRM series is engineered to provide consistent capacitance values while maintaining stable performance under varying electrical and thermal conditions, making these components suitable for applications where reliability and long-term stability are essential. Based on the part number structure, this particular component features a 1552 case size, which translates to compact dimensions that enable dense PCB layouts without sacrificing performance. This size category is popular in space-constrained applications where engineers must balance component density with electrical requirements. The designation indicates this is a ceramic capacitor optimized for general-purpose use in both consumer and industrial electronics. Murata's GRM series capacitors are commonly specified in power management circuits, audio equipment, telecommunications infrastructure, automotive electronics, medical devices, and industrial control systems. Their construction using multilayer ceramic technology provides high volumetric efficiency, meaning designers can achieve required capacitance values in minimal board space. This makes them particularly valuable in compact devices and high-density circuit boards where real estate is at a premium. Engineers typically select specific GRM series parts based on required capacitance value, voltage rating, tolerance, and temperature stability characteristics. The particular capacitance value encoded in this part number makes it suitable for specific filtering or coupling applications where standard values are required. Murata's manufacturing consistency and quality control make their capacitors a reliable choice for original equipment manufacturers and contract manufacturers who need components that meet stringent performance requirements across production runs. The ceramic material composition in these capacitors provides inherent advantages including low equivalent series resistance, relatively low equivalent series inductance compared to older technologies, and excellent frequency response characteristics. These properties make GRM series capacitors particularly effective in high-frequency applications and modern power distribution scenarios. For engineers evaluating this component, consideration should be given to the specific application requirements including voltage stress levels, operating temperature range, frequency of operation, and any specialized environmental conditions such as vibration or moisture exposure. Murata's extensive documentation and application notes support proper component selection and circuit design optimization.
