GRM1555C1H161JA01D

The GRM1555C1H161JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This particular part belongs to 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 like this model function as energy storage and filtering elements in electronic circuits. They are essential for smoothing voltage ripple, decoupling power supplies, blocking DC while passing AC signals, and stabilizing circuit performance in countless applications. The GRM series is specifically designed for mainstream industrial and commercial use rather than specialized high-reliability or military applications, making it a cost-effective choice for volume production. The "1555" in the part number indicates the physical package size using the standard metric code. This compact form factor allows for space-efficient PCB layout, which is particularly valuable in modern electronics where board real estate is at a premium. The small footprint also contributes to lower parasitic inductance, which helps maintain capacitive performance at higher frequencies—an important consideration in switching power supplies and high-speed digital circuits. Murata's GRM family offers a range of voltage and capacitance ratings to accommodate diverse circuit requirements. These capacitors are typically specified in applications including power distribution networks, RF/microwave circuits, audio equipment, medical devices, and automotive electronics. Their reliability and consistency make them a standard choice for design engineers who need proven, off-the-shelf solutions that can be sourced reliably across multiple production runs. Engineers select this specific part number when their circuit design requires the exact combination of physical dimensions, voltage rating, capacitance value, and dielectric material that this variant provides. Rather than designing around alternative components, specifying this exact Murata part ensures compatibility with existing bill-of-materials standards, simplifies inventory management, and leverages the performance characteristics that the design validation phase has already confirmed. The GRM series represents a mature, well-established technology with extensive field history across multiple industries. This established track record, combined with Murata's manufacturing scale and quality control systems, makes these capacitors a dependable choice for applications where consistent performance and supply chain stability are important considerations alongside technical specifications.
