CL31C221JIHNMPE

The CL31C221JIHNMPE is a multilayer ceramic capacitor manufactured by Samsung, representing a reliable component choice for general-purpose electronic applications across industrial and consumer electronics sectors. This capacitor belongs to Samsung's established family of ceramic capacitors, which are fundamental passive components used to store electrical energy and filter signals in circuits. Multilayer ceramic capacitors like this model are among the most widely deployed passive components in modern electronics due to their compact size, cost-effectiveness, and consistent performance characteristics. The "CL31" designation indicates this part is from Samsung's general-purpose ceramic capacitor line, designed to meet standard industrial requirements without specialized performance demands. These capacitors are constructed using alternating layers of ceramic dielectric material and metallic electrodes, allowing manufacturers to achieve useful capacitance values in minimal physical space. The part number suffix provides information about the component's specifications. The "221" portion of the designation typically relates to the capacitor's capacitance value within Samsung's naming convention. The "J" designation generally indicates the component's tolerance class, while the "H" references the voltage rating category common in this product family. The "PE" suffix indicates the lead-free, RoHS-compliant termination finish, making this component suitable for modern manufacturing environments requiring compliance with environmental and safety regulations. This capacitor is commonly specified in applications including power supply filtering, signal coupling and decoupling, timing circuits, and general noise suppression across consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. Engineers choose multilayer ceramic capacitors for their reliability, temperature stability within specified operating ranges, and excellent high-frequency performance compared to alternative capacitor technologies. The CL31 series maintains consistent electrical characteristics across production batches, making it suitable for applications where component matching and predictable performance are important. These capacitors typically exhibit low equivalent series resistance and inductance, characteristics that make them effective for decoupling applications where rapid charge delivery is required to suppress voltage transients. When selecting the CL31C221JIHNMPE specifically, engineers benefit from Samsung's quality reputation and the widespread availability of this standardized component across multiple supply channels. The lead-free termination finish ensures compatibility with modern reflow soldering processes and long-term reliability in assembled circuits. This part represents a practical choice for designers seeking proven, standards-compliant ceramic capacitor solutions without requiring specialized or enhanced performance characteristics that would justify more expensive alternatives.
