The CL05C221JB51PNC from Samsung is a high-precision, surface-mount technology (SMT) Multilayer Ceramic Capacitor (MLCC). It is designed to offer a stable 220 picofarads (pF) capacitance value with a tight tolerance of ±5%, ensuring precise performance in critical circuit segments. Operating at a voltage rating of 50 volts, this capacitor features the C0G (NP0) temperature coefficient, one of the most stable and reliable over temperature and applied voltage, making it perfect for timing, tuning, and filtering applications where low losses and stability are essential. The small 0402 package size is particularly beneficial for miniature and high-density electronic devices, including smartphones, IoT devices, and medical instruments, where space is at a premium and performance cannot be compromised.
