GRM1552C1H221JA01D

The GRM1552C1H221JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive components. This part belongs to Murata's GRM series, which is widely recognized across industrial and consumer electronics applications for consistent quality and reliable performance. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic circuit. They store electrical energy and are essential for filtering, decoupling, coupling, and signal conditioning applications. The GRM series is engineered to meet stringent performance requirements across automotive, industrial control, telecommunications, and consumer electronics segments. The part number structure indicates this is a surface-mount device in a compact 1552 case size (metric dimensions 4.0 x 3.2 mm), making it suitable for space-constrained PCB layouts where board real estate is at a premium. The 1552 package is a standard industry format that balances component footprint with mounting reliability and thermal characteristics, commonly specified in modern compact designs. Murata's GRM series capacitors are available across a wide range of specifications including various voltage ratings, capacitance values, and temperature coefficients. The "C1H" portion of this part number indicates specific electrical characteristics within the series. Engineers typically select from this family when they need predictable performance across temperature ranges common in industrial environments, including applications subject to thermal cycling or extreme ambient conditions. Key reasons an engineer might specify this exact part include the established reliability history of Murata's GRM components in production environments, consistent availability from multiple distribution channels, and qualification in many existing designs. The compact case size allows design flexibility without sacrificing electrical performance. Additionally, Murata maintains strict manufacturing controls and traceability standards, which is critical for applications requiring compliance with industry certifications or military specifications. The GRM series is particularly valued in applications requiring stable capacitance over time and temperature, making it suitable for precision analog circuits, power supply filtering, high-frequency signal conditioning, and impedance matching networks. In industrial control systems, telecommunications infrastructure, and automotive electronics, these capacitors provide the stability and longevity that end-users depend on for continuous operation. Engineers should consult Murata's technical documentation for this specific part number to verify capacitance value, voltage rating, temperature coefficient, and other performance parameters relevant to their application requirements, ensuring proper circuit design and regulatory compliance.
