CL21A106MPCLQNC

# CL21A106MPCLQNC - Samsung Multilayer Ceramic Capacitor The CL21A106MPCLQNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely-used component in modern electronics. This capacitor belongs to Samsung's established line of general-purpose ceramic capacitors, designed to meet the demanding requirements of both consumer and industrial applications. Multilayer ceramic capacitors like this model are fundamental passive components found in virtually every electronic device and circuit board produced today. They serve critical functions including signal filtering, noise suppression, power supply smoothing, and AC coupling across a broad range of applications. Engineers rely on MLCCs for their compact size, reliability, cost-effectiveness, and high-frequency performance characteristics. The CL21A designation indicates this capacitor uses the 0805 metric package (also known as 2012 in imperial measurements), making it compatible with standard surface-mount technology (SMT) assembly processes. This compact package footprint allows for high-density PCB designs while remaining easy to handle and place using automated manufacturing equipment. The 0805 package represents an industry-standard size that has remained popular across decades, ensuring broad design flexibility and straightforward sourcing. As a ceramic dielectric capacitor, this component is ideally suited for applications requiring stable performance across temperature ranges and frequency bands typical in consumer electronics, telecommunications equipment, automotive systems, industrial control boards, and computer peripherals. The multilayer construction provides improved capacitance density compared to single-layer designs, delivering usable capacitance in a small physical footprint. Engineers typically specify capacitors like the CL21A106MPCLQNC when designs require compact surface-mount components with established performance history, reliable supply chains, and cost-effective manufacturing. The widespread adoption of this family means robust design resources, extensive reference circuits, and predictable long-term availability. The part's maturity in the market also means manufacturers have thoroughly characterized its behavior in real-world applications. The "MP" designation within the part number indicates specific performance characteristics within Samsung's product family, while the alphanumeric suffix denotes specific packaging and lead-finish specifications. For engineers selecting between alternatives, this particular variant may be chosen to match exact board assembly requirements, thermal performance needs, or existing supply-chain qualifications. This component integrates seamlessly into modern PCB designs and works effectively in both DC blocking applications and high-frequency filtering scenarios. Its reliability, proven track record, and standardized specifications make it a trusted choice for OEMs and design engineers across multiple industries seeking dependable passive component performance.
