The V3R9B0201C0G500NAT is a small, surface-mount multilayer ceramic capacitor (MLCC) manufactured by VIIYONG. It has a capacitance of 3.9 picofarads (pF) and a rated voltage of 50 volts, and is a 0201 sized part with a RoHS-compliant lead-free design. Its small size and high capacitance make it an ideal choice for applications such as filters, resonant circuits, signal integrity architectures, biomedical instruments, and so on. Furthermore, because of its robust structure and low profile, it is well-suited for use in surface-mount applications, such as printed circuit boards and other electronic components.
