GRM1552C1E820JA01D

The GRM1552C1E820JA01D is a multilayer ceramic chip capacitor manufactured by Murata, one of the world's leading producers of passive electronic components. This part belongs to the GRM series, which represents Murata's general-purpose ceramic capacitor line designed for mainstream industrial and commercial applications. Multilayer ceramic capacitors (MLCCs) like this component are fundamental passive elements found in virtually every modern electronic circuit. They store electrical energy temporarily, filter noise from power supplies, couple and decouple signals, and stabilize voltage levels in power distribution networks. The compact chip format makes them ideal for space-constrained applications where engineers need reliable capacitance in a minimal footprint. The 1552 designation in the part number refers to the component's physical package size, following the standard EIA metric naming convention. This mid-range case size offers a practical balance between capacitance value, voltage rating, and board space efficiency—large enough to achieve useful capacitance levels while remaining suitable for automated assembly in high-volume manufacturing environments. Murata's GRM series capacitors are widely specified in consumer electronics, industrial control systems, telecommunications equipment, automotive applications, and power management circuits. They serve in filtering stages of switching power supplies, as bulk capacitors near voltage regulators, in signal conditioning circuits, and throughout analog and digital signal processing stages where stable, predictable capacitance is essential. Engineers typically select this part number when they need a capacitor that combines proven reliability, consistent electrical performance, and ready availability from multiple distribution channels. Murata's manufacturing processes ensure tight tolerances and stable capacitance characteristics across operating temperature ranges, which is critical in precision instrumentation and industrial control applications where circuit performance cannot drift significantly over time or temperature. The C1 designation in the part number indicates this capacitor uses X7R or similar temperature-compensated ceramic dielectric material, which provides relatively stable capacitance across a broad temperature range—a key advantage over basic ceramic types when designing circuits intended for industrial or outdoor environments with variable conditions. This specific part number represents a production configuration that has been validated for reliability in high-volume applications. Designers and procurement engineers often prefer established part numbers within the GRM family because Murata maintains consistent quality standards and long-term availability, reducing the risk of redesign requirements or supply interruptions during product lifecycles.
