CL21A226MQFNNNC

The CL21A226MQFNNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose applications across consumer electronics, industrial equipment, and telecommunications infrastructure. This component belongs to Samsung's CL series of capacitors, which are widely recognized for reliable performance in mainstream electronic applications. Multilayer ceramic capacitors like this unit are fundamental passive components used for energy storage, signal filtering, and noise suppression in electronic circuits. They are found in power supply circuits, signal conditioning stages, audio processing, and decoupling applications where stable capacitance over time and temperature is important. Engineers select MLCCs for their compact size, cost efficiency, and ability to handle high-frequency signals with minimal parasitic effects. The part designation itself encodes key information about this capacitor's characteristics. The "CL21A" prefix indicates this is a mid-range MLCC from Samsung's established portfolio, typically housed in a 0805 surface-mount package—a common form factor that balances ease of assembly with reasonable capacitance density. The alphanumeric suffix provides details about the capacitor's rated voltage, capacitance value, tolerance, and temperature coefficient, all of which affect how the component performs under varying operating conditions. Samsung's CL-series capacitors are engineered to meet the needs of equipment manufacturers who require consistent, proven component performance without premium pricing. These capacitors are particularly valued in cost-sensitive applications where high reliability remains essential. The series demonstrates stable electrical characteristics across typical industrial temperature ranges, making them suitable for both indoor consumer products and outdoor industrial installations. Engineers might specify this exact part number rather than alternatives based on several factors. First, established availability through distributor networks ensures consistent supply for volume production. Second, Samsung's reputation for quality control reduces the risk of field failures that could impact product reliability. Third, this component integrates seamlessly into existing designs that have already qualified against this specific part number, avoiding the time and expense of re-qualification with substitute components. Fourth, the 0805 package size offers good compatibility with standard automated assembly equipment found in most manufacturing facilities. For applications where circuit designers need a general-purpose, mid-voltage ceramic capacitor with proven long-term reliability, the CL21A226MQFNNNC represents a pragmatic choice backed by extensive market adoption across multiple industries.
