CL03A104KQ3NNND

The CL03A104KQ3NNND is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable general-purpose capacitor commonly found in consumer electronics, industrial control systems, and telecommunications equipment. This component belongs to Samsung's CL series of ceramic capacitors, which are widely specified for applications requiring compact size, cost-effectiveness, and stable performance across standard operating conditions. Multilayer ceramic capacitors function as energy storage and filtering elements in electronic circuits. They are essential for power supply filtering, signal coupling and decoupling, noise suppression, and timing applications. The CL03A series specifically uses a 0402 metric package (1.0mm × 0.5mm), making it ideal for space-constrained designs where board real estate is at a premium. This compact footprint has made the 0402 package a standard choice in modern consumer and industrial electronics, from smartphone components to industrial IoT devices and automotive electronics. The designation in this part number indicates this is a ceramic capacitor with specific electrical characteristics suitable for general-purpose applications. Samsung's CL series capacitors are known for their consistent performance, low equivalent series resistance (ESR), and reliability across temperature variations encountered in typical industrial and consumer environments. These capacitors are RoHS compliant and meet international standards for electronic components, making them suitable for applications with environmental and regulatory requirements. Engineers typically specify this exact part number when they require a proven, cost-effective solution that meets established design requirements without over-specification. The CL03A series has extensive historical use in production electronics, meaning designers can reference proven circuit designs and manufacturing processes. Samsung's strong quality reputation and wide global availability ensure supply chain reliability for both prototype and production quantities. The 0402 package size of this capacitor makes it compatible with standard surface-mount assembly processes used in modern PCB manufacturing. Its small footprint allows for higher component density on circuit boards, reducing overall device size and weight—critical factors in portable electronics and space-limited industrial applications. When choosing between ceramic capacitor options, designers consider package size, voltage rating, capacitance value, temperature stability, and cost. The CL03A series represents a mature, well-established product line that balances these factors effectively for mainstream applications. This makes the CL03A104KQ3NNND a standard specification in countless production designs where reliable, compact energy storage and filtering are needed without specialized performance requirements.
