GRM1555C1E330JA01D

The GRM1555C1E330JA01D 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 represents a broad family of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors are among the most commonly specified passive components in modern electronics. They function as energy storage devices, filtering elements, and signal coupling/decoupling components in circuits. The GRM series specifically is designed to offer reliable performance across a range of industrial and commercial applications where cost-effectiveness and stable electrical characteristics are required. The part number structure reveals several key details about this component's specifications. The "1555" in the part number indicates the physical package size, which is a 0402-equivalent form factor—a very small surface-mount package measuring approximately 1.0 mm × 0.5 mm. This compact size makes it ideal for high-density PCB designs where space is at a premium, such as in mobile devices, IoT sensors, wearables, and compact industrial controllers. The "C1E" designation within the part number refers to the dielectric material and voltage rating class. Components with this rating are typically specified for general-purpose applications requiring moderate voltage withstand capability and stable capacitance across operating temperature ranges. Engineers typically specify this exact part when they need a small-footprint, reliable ceramic capacitor for standard decoupling, filtering, or bypass applications in consumer and industrial circuits. The GRM series reputation for consistency and availability makes it a preferred choice for design engineers who need to balance performance requirements with supply chain reliability and cost considerations. Murata's manufacturing quality and extensive testing ensure that parts like the GRM1555C1E330JA01D meet strict industry standards, making them suitable for applications where component failure could impact system reliability. The 0402 package size, combined with the GRM series' proven track record, makes this part particularly valuable for engineers designing compact equipment that cannot tolerate larger component footprints. This capacitor would be specified alongside other passive components in filtering networks, power supply circuits, high-frequency signal paths, and stabilization circuits throughout industrial and consumer electronic equipment. Its small size and established reliability make it a foundational choice in countless electronics designs worldwide.
