GRM155R61A333KA01D

The GRM155R61A333KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components that store electrical charge and are essential in virtually every modern electronic device. The GRM series capacitors are designed for mainstream applications requiring reliable performance at competitive cost points. These capacitors consist of multiple layers of ceramic dielectric material interleaved with internal electrodes, enabling high capacitance values in compact packages. The "155" designation in the part number indicates this capacitor uses a 0402 metric package size (1.0mm × 0.5mm), making it suitable for high-density printed circuit board layouts. This compact form factor is particularly valuable in space-constrained applications such as mobile devices, portable instrumentation, and modern automotive electronics where PCB real estate is at a premium. Despite the small size, MLCCs in this package deliver meaningful capacitance values, making them extremely versatile. The "R61" portion of the part number identifies the voltage rating class for this component. Murata's alphanumeric coding system allows engineers to quickly identify key electrical characteristics during component selection. The "A333" segment specifies the capacitance value within the standard E12 or E24 series progression, typical for industrial component standardization. Engineers specify this exact part number when they need the combination of compact packaging, reliable performance, and the specific electrical characteristics defined by Murata's GRM155R61A series. These capacitors are frequently used in decoupling applications near integrated circuits, filtering in power supply circuits, and AC coupling in signal conditioning stages. The ceramic dielectric material provides stable performance across temperature ranges encountered in industrial and consumer environments, though capacitance may vary slightly with temperature and applied voltage—characteristics inherent to ceramic technology. Murata's manufacturing quality and consistency make GRM series capacitors a trusted choice for engineers designing everything from simple consumer products to complex industrial control systems. When design specifications call for a proven, widely-available ceramic capacitor in a 0402 package with specific voltage and capacitance characteristics, the GRM155R61A333KA01D provides a reliable, cost-effective solution that meets the needs of volume production.
